Boiler back end ductwork equipment low-temperature corrosion solves and improves waste heat recycling energy utilization rate for different types of coal, so that more than flue gas
Heat utilization is wider using territorial scope, while promoting boiler efficiency, reducing system assembles cost, wants in realization flue gas emission environmental protection
Have while asking and economizes on coal, it is water-saving, reduce the Social benefit and economic benefit of smoke discharge amount.
For example in, winter condition, environment temperature can be reduced to 0 DEG C, and steam air heater leaving air temp can be constant at this time, only
Leaving water temperature is reduced to 40 DEG C or so.So operation just counteracts influence of the environment temperature reduction to exhaust gas temperature, in pot
Under the premise of furnace exhaust gas temperature is unaffected, low temperature electric dust removal requirement original fume high-temperature radiator exit gas temperature be 90 DEG C and
It eliminates to emit neat stress required by white cigarette and be heated to 90 DEG C of operating parameter and be attained by.
When summer operating mode, environment temperature can be increased to 40 DEG C, and steam air heater leaving air temp can be constant at this time, only water temperature out
Degree is increased to 60 DEG C or more and returns to condensate system.So operation also counteracts environment temperature raising to the shadow of exhaust gas temperature
It rings, under the premise of exhaust gas temperature is unaffected, low temperature electric dust removal requirement original fume high-temperature radiator exit gas temperature
For 90 DEG C and eliminates to emit neat stress required by white cigarette and be heated to 90 DEG C of operating parameter and be attained by.
When underrun operating condition, environment temperature can change between 0~40 DEG C, and steam air heater leaving air temp can mention at this time
For height to 70 DEG C, leaving water temperature can return to condensate system between 40~60 DEG C.So operation also just counteracts unit load change
Change to the influence to exhaust gas temperature, under the premise of exhaust gas temperature is substantially unaffected, low temperature electric dust removal requirement is former
Fume high-temperature radiator exit gas temperature is 90 DEG C and elimination emits the operation ginseng that neat stress required by white cigarette is heated to 90 DEG C
Number is attained by.
View of the foregoing, it will be seen that the operating parameter variation of steam air heater is very greatly, so reasonable request will be proposed to the design of steam air heater,
Under the premise of calculation and check various operating conditions, and the reality of steam air heater can be significantly increased using the WGGH system of the present embodiment
Heat exchange area is arranged on border, promotes boiler backheat utilization efficiency；More effectively adapt to different geography regional environments, extension flue gas benefit
With the use scope of residual neat recovering system.

It is respectively equipped with First air steam air heater 11, Secondary Air steam air heater 13.
The water inlet of former fume high-temperature radiator be derived from the 7th grade it is low plus 1 condensation water inlet, the 7th grade it is low plus 1 condensed water
Export low with the 6th grade plus 2 the mixing waters for condensing water inlet.The water outlet of former fume high-temperature radiator enters neat stress reheater
9, enter back into First air steam air heater 11 and Secondary Air steam air heater 13, from steam air heater come out water return the 7th grade it is low plus 1 condensation
Water inlet.Former fume high-temperature radiator, neat stress reheater 9 exist together with First air steam air heater 11 and Secondary Air steam air heater 13
Water side be parallel to the 7th grade it is low plus 1 inlet and outlet between.The smog discharge temperature of neat stress reheater 9 can be risen to 90 DEG C in this way
More than, it realizes that eliminating boiler tail chimney emits white cigarette, solves and improve waste heat recycling energy utilization rate, energy conservation for different types of coal
While again environmental protection purpose.
As further improvement of this embodiment, first passage is divided into two-way, first via warp after passing through neat stress reheater 9
Crossing First air steam air heater 11, the second tunnel, then two-way collaborates again by Secondary Air steam air heater 13, is connected to the 7th grade of low plus 1 pipe
Road rear end.
The water inlet of former fume high-temperature radiator from the 7th grade it is low plus condensation water out, 80 DEG C of water temperature herein, through former flue gas
Condensed water after the heating of high temperature exothermic device is introduced into neat stress reheater 9 and enters back into 13 system of First air and Secondary Air steam air heater,
Then return again to the 7th grade it is low plus 1 import, formed neat stress reheater absorb fume afterheat heating neat stress simultaneously reduce unit
One circulation of coal consumption.
As further improvement of this embodiment, the first via and the second tunnel be connected to after collecting the 7th grade it is low plus 1 between
Pipeline is equipped with the first valve 15.
As further improvement of this embodiment, second channel is equipped with the second valve 16.
