Flue gas reheating and gas heating device

  Tube regenerator
The tubular flue gas regenerator refers to a tubular direct gas-to-gas heat exchanger . 或者烟气温度太高 超过 3 00 可采用烟气回热器。 When the flue gas flow is small or the temperature of the flue gas is too high , when it exceeds 3 00 , a flue gas regenerator can be used.

Media type regenerator (MGGH)

(水或者导热油)为循环载热介质,利用烟气余热预热烟气的回热设备,包括烟气冷却器和烟气加热器及循环系统等设备。 The medium gas-gas heat exchanger uses the medium (water or heat-conducting oil) as the circulating heat-carrying medium and uses the flue gas waste heat to preheat the flue gas, including flue gas coolers, flue gas heaters, and circulation systems. . GGH )体积小,阻力小,便于烟道布置,成本低,因此优于回热器。 In the case of a large amount of flue gas, the medium heat exchanger ( MGH ) has a small volume and a small resistance, which is convenient for the layout of the flue and the cost is low, so it is better than the regenerator.

烧结机烟气 等无法进行高尘脱硝的情况下,低温烟气需要重新加热到适合脱硝的温度,如中温脱硝的 2 60 - 280 和低温脱硝的 1 80 - 220 When high-density denitrification is not possible for waste incineration flue gas and sintering machine flue gas , low-temperature flue gas needs to be reheated to a temperature suitable for denitrification, such as 2 60-280 ℃ at medium temperature and 1 80-220 ℃ at low temperature. . M GGH 回收 最大限度地减少燃料消耗 After the reaction, the high-temperature flue gas waste heat can be recovered through M GGH , which minimizes fuel consumption . ,可 用导热油为媒质的 M GGH 换热元件为碳钢翅片管 At this temperature , M GGH can be used as the medium of heat transfer oil , and carbon steel finned tubes are used as heat exchange elements .


The tail denitration flue gas heating system includes three parts: flue gas heater, flue gas cooler, and gas heater.  

  In order to reduce the amount of heat-conducting oil and lower the pressure head of the oil pump, the high-temperature part can be heat-exchanged with heat-conducting oil, and the low-temperature part can be exchanged with water as the medium, which is the most economical.


Gas heating device

可用天然气 高炉煤气 焦炉煤气等 The gas heater is used to raise the flue gas temperature to the denitration temperature . Natural gas , blast furnace gas , and coke oven gas can be used . 氧浓度高于 1 5 % 用内置式燃气加热器 不需要鼓风 氧浓度低于 1 5 % 用外置式燃气加热器 需要鼓风助燃 The gas heater is a flue-type structure . When the oxygen concentration is higher than 15 % , the built-in gas heater is used , and no blast is required ; when the oxygen concentration is lower than 15 % , the external gas heater is used , and blast is required to assist combustion .
