Definitions

  • the invention relates to a method for burning lean fuel gas, such as gas from gasification of biofuel or waste, in a furnace of a power plant boiler.
  • the invention also concerns a burner for burning lean fuel gas.
  • coal and oil are mainly combusted by means of dedicated burners in different kinds of boilers.
  • carbon dioxide which is a greenhouse gas
  • renewable fuels of biological origin could be used to replace part of coal and oil. The method is then called co-firing of coal/oil and biofuels.
  • One practical way of carrying out co-firing comprises gasification of biofuels and combustion of the lean product gas thus produced in a boiler by separate burners.
  • An advantage of this method is that gasification allows use of very heterogeneous fuels, such as wood, peat, waste, sludge, coal, etc., and it is still possible to produce fuel gas of uniform quality for burners.
  • a drawback of this method is its high investment cost.
  • the calorific value of the product gas from gasification is from about 3 to 6 MJ/m 3 n, whereas the calorific value of natural gas is about 49 MJ/m 3 n.
  • the product gas from gasification does not contain any oxygen, which is necessary for burning.
  • the temperature of the product gas is usually from 600°C to 900°C, and the gas may contain from 100 to 200 ppm hydrogen sulphide. Stable combustion of this kind of product gas with low calorific value is much more difficult than combustion of natural gas, which is why specific burning apparatus is required.
  • the high temperature and high hydrogen sulphide content together create a corrosion risk that should also be taken into consideration.
  • the product gas obtained from a separate gasifier has been fed into a furnace via burners.
  • the burners have been designed for a low axial velocity in order to assure reliable ignition, whereby the burner's dimensions have become very large.
  • the gas volume flow becomes extremely large, which further complicates the fuel feed at a low velocity.
  • Mounting large burners in an existing furnace is technically difficult, and adding new burners to an existing boiler cuts down the available heat transfer surface of the boiler.
  • the additional burners may cause fouling and flow disturbances in the furnace, because introduction of new flows changes the flow patterns in the furnace, thus altering the fuel combustion process, the flame pattern, emissions and the heat transfer on the boiler's internal surfaces.
  • the result may be deficient combustion degree of coal/oil, increased CO and NO x emissions and increased boiler corrosion. Furthermore, in the placement of lean gas burners in the existing boiler, the total heat transfer of the boiler has to be taken into consideration so that it is not changed, because that would mean reduction of the combustion efficiency of the power plant.
  • US 2008/0227040 A1 discloses a method and burner for combustion of lean fuel gas, comprising creating an inflammable pre-mixture containing air and fuel gas, ejecting the pre-mixture in rotation around a central axis, and ejecting a complementary air flow either in the center of the pre-mixture flow or around the pre-mixture flow as a peripheral complementary flow.
  • the structure of the burner is very complicated.
  • EP 0 639 742 A2 discloses a method and device for low emission combustion of gaseous fuels with internal recirculation of flue gas, particularly in water tube boilers.
  • a first part of combustion air is guided in a swirled manner as primary air coaxially with the fuel and essentially in rotational symmetry with respect to the longitudinal axis of the burner to a primary exit position.
  • a second part of the combustion air is guided in two stages as secondary air to a secondary exit position.
  • the secondary air is fed in the form of a number of free jets essentially in the direction of the primary air flow. These secondary air jets cause circulation of flue gases, which flue gases are cooler than the flame.
  • the burner according to the present invention is characterized by what is stated in claim 8.
  • a fuel gas flow is fed into a furnace via a fuel pipe, a primary air flow is fed centrally into the fuel gas flow discharging from the fuel pipe, and a secondary air flow is fed peripherally into the fuel gas flow discharging from the fuel pipe.
  • a small amount of air may be introduced into the fuel gas flow in the fuel pipe.
  • the outlet of the fuel pipe is provided with an inner and an outer stabilizing ring that contribute to the flame ignition.
  • the primary and the secondary air channels are provided with swirlers that set the respective air flows into rotation.
  • the product gas received from a biofuel gasifier is oxygen-free and its temperature is typically in the range of 600°C to 800°C. This being the case, producing a stable gas flame requires efficient mixing of air with the fuel gas to create a combustible mixture.
  • the novel gas burner supports mixing the air and the fuel gas in several significant ways. Firstly, part of the combustion air - from 20 to 40% of the total amount - is supplied as primary air via a primary air channel in the center of the fuel gas flow. The primary air flow is given a drastic tangential acceleration at the outlet of the primary air channel, thus boosting the mixing of the air with the surrounding fuel gas flow.
  • Part of the secondary air may be introduced into the fuel pipe through separate nozzles arranged in the separating wall to increase the oxygen content of the fuel gas already in the fuel pipe.
  • the secondary air flow is given a high velocity, preferably in the range of 40 to 60 m/s.
  • the share of secondary air is preferably from 60 to 80% of the total amount of combustion air. Mixing of combustion air with fuel gas improves as the velocity difference increases.
  • the velocity of the fuel gas can be maintained in the range of 15 - 30 m/s, preferably 20 to 25 m/s.
  • the secondary air flow can be forced to efficiently mix with the fuel gas.
  • Rapid ignition of fuel gas can be secured by means of flame stabilizing rings fitted in connection with the outlet of the fuel pipe. Rapid ignition also requires intense swirl numbers of the primary and secondary air flows.
  • the swirl numbers should preferably be in the range of 0.6 - 1.0. Cutting down the swirl number would impair ignition.
  • the fuel pipe is made of corrosion resistant stainless steel, which preferably contains more than 15% chromium. Calculations have shown that in the novel burner a chromium oxide layer is formed on the metal surface, limiting the corrosion rate to an acceptable level.
  • the flame ignites rapidly and bums stably. This is achieved by utilizing specific flame stabilizing rings and by setting the velocities of the combustion airs and the fuel gas to an optimal level.
  • the furnace may be started up directly by the new fuel gas burners. In that case, the heavy fuel oil fired start-up burners that have previously been used for ignition can be eliminated. Heavy fuel oil is expensive and tends to cause detrimental emissions.
  • Slag-formation can be prevented by guiding a large amount of protective secondary air close to the refractory burner throat and by increasing the velocities of air flows.
  • oxygen-rich conditions will be generated in the vicinity of the refractory throat and the burner throat will remain clean.
  • Slagging of the fuel pipe can be further prevented by increasing the velocity of the fuel gas flow.
  • the novel burner Due to the good ignition and the stability of the flame, the novel burner enables very low air-fuel ratio of the flame, such as 0.6 - 0.8, combined with the over-fire system of the boiler. This makes it possible to reach very low level of nitrogen oxide emissions.
  • the new burner produces a short flame, which is easy to fit in the furnace in such a way that the flame does not cause detrimental corrosion of the boiler walls and/or deteriorate the other burners of the furnace.
  • the novel lean gas burner can be installed in existing boilers or in new boilers. When renovating an existing power plant boiler, care should be taken of the accompanied changes in the over-fire space.
  • the boiler may be operated solely with lean fuel gas or it may be a boiler co-firing e.g. coal or oil and the product gas.
  • the novel lean gas burner Due to high air and gas velocities, the novel lean gas burner has smaller dimensions than the prior-art lean gas burners. That is why the holes needed in the water wall of the furnace are not as large as when using the prior-art gas burners.
  • FIGS. 1 and 2 illustrate a gas burner suitable for burning lean fuel gas, such as product gas from gasification of various kinds of biofuel or waste material.
  • the burner comprises a fuel pipe 1 for feeding fuel gas into a furnace, a primary air channel 2 arranged centrally in the fuel pipe 1, and a secondary air channel 6 arranged circumferentially around the fuel pipe 1.
  • a fuel pipe 1 for feeding fuel gas into a furnace
  • a primary air channel 2 arranged centrally in the fuel pipe 1
  • a secondary air channel 6 arranged circumferentially around the fuel pipe 1.
  • auxiliary fuel firing tube 5 which may provide a jet of liquid fuel, such as light fuel oil, when the combustion furnace is started up.
  • a gas igniter 11 arranged in the fuel pipe 1.
  • the fuel firing tube 5 and the gas igniter 11 are alternative means for ignition of the flame. It would be sufficient to have either of them.
  • the interior of the fuel pipe 1 is provided with deflectors 12 to guide the fuel gas flow from the inlet 13 of the fuel pipe 1 to the outlet 14 through which the fuel gas is ejected into the furnace.
  • the outlet 14 of the annular fuel pipe 1 is provided with two annular stabilizing rings 4, 8.
  • the inner stabilizing ring 4 is fitted at the end of the inner wall of the fuel tube 1.
  • the inner ring 4 comprises a plurality of tooth-like projections 15 extending radially outwards into the fuel pipe 1.
  • the outer stabilizing ring 8 is fitted at the end of the outer wall of the fuel tube 1.
  • the outer ring 8 comprises a plurality of tooth-like projections 16 extending radially inwards into the fuel tube 1.
  • the second stabilizing ring 8 comprises an annular section 17 extending outwards into the secondary air channel 6.
  • the two stabilizers 4 and 8 are arranged such that they generate turbulence in the fuel gas flow ejecting from the fuel pipe 1, which makes it easier to mix the turbulent fuel gas flow with the tangential primary air flow injected from the primary air channel 2 and the tangential secondary air flow injected from the secondary air channel 6.
  • the stabilizing rings 4 and 8 form a two-part flame holder.
  • the primary air channel 2 is provided with a first swirler 3 that sets the primary air flow in a rotation close to the outlet of the primary air channel 2.
  • the swirler 3 is fixed to the auxiliary fuel firing tube 5.
  • the secondary air channel 6 is provided with a second swirler 7 that sets the secondary air flow in rotation close to the outlet of the secondary air channel 6.
  • the angle of the blades of the second swirler 7 may be adjustable in order to control the rotation of the secondary air flow discharging from the secondary air channel 6.
  • the outer wall of the fuel pipe 1 is provided with a plurality of nozzles 9 that allow introduction of air from the secondary air channel 6 into the fuel pipe 1.
  • the number of the nozzles 9 in the outer wall of the fuel pipe 1 may be 5 - 10.
  • the amount of air introduced into the fuel pipe 1 through the nozzles 9 may be adjustable in the range of 10 - 20% of the total amount of secondary air.
  • the fuel gas is injected to the furnace via the fuel pipe 1, which is advantageously made of high-chromium stainless steel.
  • the velocity of the fuel gas flow is adjustable in the range of 15 - 30 m/s, preferably 20 - 25 m/s.
  • the fuel gas is mixed with a small amount of secondary air introduced through nozzles 9 in the fuel pipe 1.
  • the primary air channel 2 injects a tangential primary air flow into the fuel gas flow discharging from the fuel pipe 1, and the secondary air channel 6 injects a tangential secondary air flow around the fuel gas flow discharging from the fuel pipe 1.
  • the velocity of the primary air flow may be adjustable in the range of 15 - 40 m/s.
  • the velocity of the secondary air flow may be adjustable in the range of 40 - 60 m/s.
  • the two stabilizing rings 4 and 8 assist in mixing the fuel gas with the tangential air flows.
  • the burner is fixed in the wall of the furnace via a refractory throat 10 that surrounds the outlet of the secondary air channel 6.
  • the refractory throat 10 has a burner throat angle in the range of 0 - 10°.
  • the air flow ejecting from the secondary air channel 6 is arranged to flush the surface of the refractory throat 10, thus cooling the surface of the burner throat 10 and preventing slagging.
  • the annular section 17 of the outer stabilizing ring 8 helps in guiding the secondary air flow to flush the surface.
  • Burning may be carried out with an air-fuel ratio of 0.6 - 0.8, which ensures that the generation of nitrogen oxides is minimized.
  • the flame provided by the burner is relatively short and hot. Thus the flame does not disturb the operation of any other burners in the furnace.
  • the air supply is advantageously divided such that 20 - 40% of the total amount of burner air is supplied to the flame via the primary air channel 2 and 60 - 80% of the total amount of burner air is supplied to the flame via the secondary air channel 6.
  • the relationship between the two air flows can be adjusted by control dampers arranged in the pipes supplying air into the primary air channel 2 and the secondary air channel 6.
