Definitions

  • VDI guidelines 2442 of June 1987 suggest heating the exhaust air in a post-combustion system to about 750 ° to 900 ° C using a burner and then cooling it again with a heat exchanger.
  • the exhaust air to be cleaned is heated in counterflow so that the fuel consumption can be kept as low as possible.
  • Such an locations are extremely expensive and, apart from reducing the environmental impact, have no benefit.
  • the waste heat still contained in the gas is rarely economically usable.
  • the gas-gas heat exchanger operated at high temperature also poses considerable material problems, so that a desired temperature above 800 ° C is often not allowed to be driven.
  • the invention has for its object to provide a method and a system for cleaning the exhaust air of a tenter or scab, with which the exhaust air can be cleaned as completely as possible and its heat content can be recovered as possible. This object is achieved by the combination of features according to claims 1 and 6.
  • Textile finishing companies with tenter frames or scabs usually have steam boilers of sufficient size to clean the entire exhaust air from the tenter frame or scabs in the manner according to the invention.
  • these companies there is only a thermally insulated exhaust air line between the stenter and the boiler as well as a change of the boiler control, possibly also of the burner.
  • the waste heat can be recovered and the fuel costs reduced significantly.
  • the high excess of air in the process according to the invention also results in a marked reduction in the NO x content in the exhaust gas.
  • a tenter frame 1 has a housing 2, which is closed on all sides, with an inlet slot 3 and with an outlet slot 4 for a fabric web 5.
  • the interior of the housing 2 is connected to a suction blower 7 via an exhaust air line 6.
  • the fan 7 promotes the exhaust air in a thermally insulated connection Line 10.
  • the insulation of line 10 serves on the one hand to avoid heat losses, and on the other hand to avoid condensation of water and pollutants from the exhaust air.
  • the connecting line 10 is connected to the combustion air supply opening 12 of a burner 13 of a steam boiler 21.
  • a further thermally insulated line 11 extends between the opening 12 and the burner 13.
  • the combustion air is fed to the burner 13 via a burner fan 14.
  • a compensating chimney 15 branches off from the line 10.
  • a fresh air intake 22 branches off from the line 11. Controlled by a flap 23, the combustion air is obtained either from the line 10 or from the nozzle 22.
  • the burner 13 has a fuel nozzle 24 with a fuel feed line 25.
  • a fuel valve 26 for regulating the fuel flow is arranged in the feed line 25.
  • a steam line 27 and an exhaust gas line 28 are connected to the steam boiler 21.
  • Three heat exchangers 29, 30, 31 are arranged in the exhaust line 28, the first heat exchanger 29 cooling the exhaust gas and thus preheating the boiler feed water conveyed by a pump 34 from a feed water tank 32.
  • the preheated feed water is fed to the boiler 21 via a feed line 33.
  • the tank 32 is fed with fresh water via a line 35.
  • the fresh water is preheated by the second heat exchanger 30.
  • the heat exchanger 31 is used to heat process or heating water.
  • the cooled exhaust gas escapes through a chimney 36.
  • the fuel valve 26 is regulated by a regulator 40.
  • the controller is given the setpoint e.g. the steam pressure of the boiler 21 measured by a sensor 41 is predetermined. When the vapor pressure drops, the valve 26 opens proportionally.
  • the regulator 40 regulates a flap 42 in the combustion air supply duct 43 of the burner 13.
  • Natural gas is expediently used as fuel.
  • the exhaust gas in the heat exchangers 29, 30, 31 can be cooled below the dew point and thus both the sensible and the latent waste heat of the stenter exhaust air can be largely recovered.
  • the upper calorific value of the fuel and the pollutants in the exhaust air is used. Due to the high excess of air, the combustion is reduced material requirements reached up to around 20%.
  • the heat exchangers 30 and 31 are expediently omitted.
  • the burner 13 ' is supplied with primary and secondary air controlled by the flap 42 as a function of the boiler load, the excess air again increasing as the boiler load decreases.
  • Another channel 50 branches off from channel 43 upstream of flap 42. This opens into an annular space 51 around the channel 43.
  • An annular channel 52 leads from the annular space 51 to the burner head in the boiler 21. Via this annular channel 52, tertiary air can be fed to the burner head.
  • a flap 53 is arranged in the channel 50. The flap 53 is controlled by a further controller 54.
  • the controller 54 receives the difference between the exhaust air temperature upstream and downstream of the compensating chimney 15 as a setpoint.
  • a temperature sensor 55 is arranged in each of the lines 10, 11.
  • the temperature difference is set to 5 ° C., for example, so that a small amount of fresh air always flows in through the chimney 15. If the temperature difference increases, the controller 54 reacts and proportionally closes the flap 53. When the temperature difference decreases, the flap 53 is opened.
  • FIG. 3 shows a third embodiment of the invention, the same reference numerals being used for the same parts.
  • the burner 13 ⁇ in turn has a tertiary air duct 50, 51, 52.
  • the flap 42 for primary and secondary air is decoupled from the fuel control valve 26 and is controlled by a servomotor 60.
  • a second servomotor 61 controls the tertiary air damper 53.
  • the two servomotors 61 are regulated by a temperature sensor 62 in the compensation chimney 15. This regulation works analogously to that with the two temperature sensors 55 in FIG. 2: the setpoint value of the temperature of the sensor 62 is set, for example, about 10 ° C. above the outside temperature.
  • the signal from the sensor 62 is applied to the two servomotors 60, 61 via two controllers 63, 64.
  • a variable upper limit of the opening cross section is provided in the controller 64.
  • the upper limit is given to the controller 64 by a temperature sensor 66 at the end of the flame tube of the boiler 21. At this point, the temperature should not fall below 800 ° so that the safe combustion of all pollutants is guaranteed and the emission of CO is avoided.
  • This configuration achieves an optimal efficiency over the entire load range of the boiler 21 with minimal fresh air intake.
