Definitions

  • the invention relates to a device for incinerating waste comprising rows of secondary air nozzles.
  • the invention relates to a method for controlling several parameters of secondary air injection including at least one of the parameters: flow, speed, turbulence, volume, composition and temperature, for optimizing the incinerating process in an incineration system.
  • the invention relates to a method for controlling primary air injection.
  • the invention also relates to an incineration equipment, functioning in accordance with said methods enabling the control of primary and secondary air injection.
  • the combustion process of waste is a rather complex one because homogeneous and heterogeneous reactions take place, not only on the incineration grate, but also above the grate.
  • the furnace-boiler part comprising a combustion chamber and a post-combustion chamber is a critical part of an incineration installation and needs to be designed with great care.
  • the most important properties for this type of furnace-boiler are good performance, high flexibility, good availability and reliability with an acceptable lifetime of the different pressure parts. Flexibility is of utmost importance, due to the variability of the waste characterized by e.g. its composition and calorific value.
  • the furnace-boiler must be able to perform under these permanent changing conditions and produce steam or heat, in an as stable as possible way.
  • the terms displacement body, bluff body and prism body are used interchangeably.
  • one of the main problems of obtaining an efficient combustion is the good mixing of the secondary air.
  • the introduction of secondary air is difficult to fine-tune.
  • adequate mixing of the secondary air with the combustible waste gases is not achieved, resulting in an incomplete combustion.
  • the introduced secondary air is often not properly conditioned to take immediately part in the post-combustion process when injected in the furnace-boiler. Consequently, it will take a longer time for the post-combustion process to reach a complete burnout of the flue gases, and injection of non-conditioned secondary air in the furnace-boiler may even slow down the post-combustion process.
  • Another problem is that the temperature throughout a cross-section of the post-combustion chamber is not constant; pockets of flue gases are sometimes hotter or cooler than the optimum temperature causing undesirable side effects such as corrosion, slagging and fouling.
  • the present invention provides a new device comprising an improvement on the primary air and secondary air injection systems, a method for controlling several parameters of the secondary air, including flow, speed, turbulence, volume, composition and temperature, and a method for controlling primary air injection.
  • a new device comprising an improvement on the primary air and secondary air injection systems, a method for controlling several parameters of the secondary air, including flow, speed, turbulence, volume, composition and temperature, and a method for controlling primary air injection.
  • the device as described above may provide secondary air via secondary air supply ducts ending in injection nozzles, passing through the front- and rear- wall of said device as well as through the membrane-wall of the displacement body.
  • the device as described above may incorporate inner front and rear walls bent in such shape that, together with the outline of the displacement body, two venturi-shaped flue gas passages with an opening angle ( ⁇ / ⁇ ) between 20° and 40° are created in order to increase the flue gas turbulence in the venturi-shaped mixing zone.
  • the device as described above may incorporate the displacement body in the shape of a distorted rhomboidal prism.
  • a method for incinerating solid materials may comprise the use of a device as described above.
  • Present invention provides a method for controlling several parameters of the primary air and secondary air injection and a device able to perform said method, which will greatly improve the efficiency of the combustion process, which will reduce emissions and will comply with the more severe combustion requirements.
  • Fig. 3a and 3b demonstrate a method according to the invention for correcting temperature imbalances due to high and low calorific value waste and depending on the heat release profile
  • Fig. 4 shows a cross-sectional view of an alternative incineration furnace-boiler or incineration device provided with a displacement body or prism [5] according to the invention, having the same features and labels as that of Figure 1a .
  • a combustion device and method may use a specific secondary air injection system in the center of the combustion 20 zone, immediately at the combustion chamber exit and before entering the post-combustion chamber, and controlled by at least one of the following parameters: flow, turbulence, volume, composition, speed, or temperature.
  • the secondary air is supplied into the divided flue gas streams "A" and "B” (see Figure 1 ), via a secondary air supply duct [12], [13], [14] to several nozzle inlets [30] and [31] in the furnace-boiler front [6] and rear [7] wall and on both sides of the displacement body [5].
  • the objective of the present invention is to optimize the combustion process in an incineration system and to assure a complete combustion of the flue gases, in order to fulfill the requirements of the EU-Waste Incineration Directive (2000/76/EC) and increase performance and lifetime of pressure part components of the incineration device.
  • EU-Waste Incineration Directive 2000/76/EC
  • the use of this new, controlled secondary air injection system leads to more effective mixing between the oxygen supplied by the secondary air and the flue gases and will increase combustion performance. Consequently, said device and method results in a much shorter and clearly defined burnout-zone of the flue gases in the post-combustion chamber of the furnace-boiler, a few meters above the displacement body.
  • the listed parameters can be adjusted according to the requirements of the incinerating process.
  • a suitable furnace-boiler geometry can contribute to a more uniform velocity and gas flow distribution and avoid flue gas recirculation or dead zones throughout the different sections of the furnace-boiter. Therefore, the furnace-boiler has a double venturi-like transition section between combustion and post-combustion chamber, which also promotes the mixing of the partial flue gas flows "A" and "B" with the injected secondary air. Improved mixing of the secondary air and the flue gases increases the efficiency of the combustion process.
  • Figure 1 shows the cross section of the furnace-boiler, combustion and post-combustion chamber of a typical incinerator arrangement, particularly designed for Incineration of solid waste or biomass, consisting of a furnace [2] with an incineration grate [25], receiving the solid materials through a feeding hopper with pusher [1].
  • the produced flue gases are conducted in a combustion chamber [3] and a post-combustion chamber (4). Hoppers [22] underneath the grate [25], are placed for collection of the siftings of the grate and serving at the same time as primary air supply channels.
  • the primary air is supplied via several air ducts [23], At the end of the grate [25], the ashes fall via a shaft [21] into an ash extractor (not shown).
  • the produced flue gases, not yet completely burned out, are divided in two streams by a displacement body [5], Installed at the entrance of the post-combustion chamber [4].
  • the displacement body [5] By placing the displacement body [5] at the combustion chamber exit [3] and the entrance into the post-combustion chamber [4], the flue gases passage is divided in two flow channels "A" and "B". Secondary air is injected through four rows of nozzles located at the entrance of the post-combustion chamber [4] where the displacement body [5] is located.
  • the secondary air is conducted via nozzles [30] in the front [8] and rear wall [7] of the furnace-boiler as well as via nozzles [31] of the displacement body [5].
  • the flue gases are mixed with secondary air, resulting in an almost complete burnout of the flue gases a few meters above the displacement body [5] and also resulting in shorter flames and more uniform oxygen concentrations.
  • the secondary air is supplied by a secondary air fan [9] via secondary air ducts [11], provided with secondary air regulating valves [15], to the secondary air supply ducts [12], [13], [14] into the injection nozzles [30], [31].
  • Control of the secondary air may be by at least one of the following parameters: flow, turbulence, volume, composition, speed, or temperature.
  • FIG. 1 An example of a device and method of how several parameters for secondary air injection are controlled according to the invention is illustrated in Figure 1 .
  • the secondary air is optimally injected directly into the flow of waste gases, at the combustion chamber exit and at the entrance of the post-combustion chamber.
  • the secondary air is injected into the divided flue gas streams "A" and "B", via a secondary air supply duct [12], [13], [14] leading to several nozzles [30], [31] located in the furnace-boiler front and rear wall and on both sides of the displacement body [5].
  • furnace-boiler front [6] and rear [7] membrane wall and the membrane wall [19] of the displacement body [5] are provided with refractory materials through which a series of nozzles [30], [31] pass.
  • the total oxygen introduced into furnace-boiler as disclosed herein as primary and secondary air may be determined by the oxygen content of the flue gases.
  • the oxygen so introduced is distributed between the primary and secondary inlet systems according to methods of the art.
  • the distribution primary and secondary air may be attenuated by monitoring the temperatures in gas flow sections A and B as described below.
  • a flue gas temperature measurement may be installed into a furnace-boiler as described herein, a few meters above the outlet of the two flue gas streams "A" and “B,” to measure the actual temperature for each flow section.
  • the purpose of this temperature measurement is to maintain, during the combustion process, nearly the same flue gas temperature (ca. 1.000°C) in front section "A” as in the rear section "B", by means of a variable secondary air flow. Consequently, when a flue gas temperature increase is observed in section "A", the secondary airflow for section "A" is increased until the equal temperature profile is automatically re-established. At the same time, secondary airflow for section “B” is reduced in order to keep the total secondary airflow constant, unless a general temperature increase is noticed in both sections whereby the total secondary airflow is increased.
  • the temperature measurement may be linked to the capability of the secondary air injection system to respond to modified furnace conditions such as a shift in the heat-release profile on the grate. For instance, when high calorific waste suddenly enters the furnace, combustion of the waste will start on the first element of the grate and the flue gas temperature in section A will rise above the temperature setpoint, so shifting the heat release profile towards the feeding hopper.
  • the setpoint may be any temperature defined by the user.
  • the set point temperature may be a value in the range of 900 to 1100 °C.
  • the system recognizes the over-temperature and the temperature imbalance and reacts accordingly as described above. A similar process, but in the opposite direction will occur when low calorific waste is introduced and combustion on the grate is delayed.
  • FIG. 3a This is exemplified in Figure 3a , wherein a temperature sensor [91], [92] is placed in each of the flue gas streams above the displacement body [5].
  • a temperature sensor [91], [92] is placed in each of the flue gas streams above the displacement body [5].
  • waste [93] enters the furnace
  • the temperature of the gas in flue stream A increases, so raising the temperature detected by the sensor [91] placed over stream A above the set point.
  • the increase in temperature and the imbalance causes more secondary air to be injected from the nozzles below the hotter stream of air [94], and also less secondary air to be injected from the nozzles below the cooler stream of air [95].
  • the detection of the temperature in the gas flow sections A and B may be used as a pre-indication of the type of waste entering the furnace, and may be connected to the process control of the grate speed and primary air distribution along the different grate elements. For instance, as in Figure 3a , when high calorific waste [93] enters a furnace as disclosed herein, combustion of the waste will start on the first element of the grate and the heat release profile of the grate will be shifted towards the waste input (hopper) end [99] of the grate. The consequence is that waste will be incinerated towards the waste input end of the grate [99]. According to the invention, the shift of heat release profile is detected by the flue gas temperature sensor in section A [91], which would rise above the temperature setpoint.
  • the setpoint may be any temperature defined as described above.
  • the system detects the over-temperature and recognizes the temperature imbalance between section A and section B, and reacts by decreasing the supply of primary air beneath or proximal to the high calorific waste [R1 to R2] so as to shift the heat-release profile back towards to the region of the post-combustion chamber.
  • the primary airflow in the remaining positions of the grate [R3 to R5] is increased in order to keep the total primary airflow constant.
  • a similar process, but in the opposite direction will occur when low calorific waste is introduced, and combustion on the grate is delayed, so shifting the heat release profile in the direction of the waste output [901] ( Figure 3b ).
