Heat exchanger 31.The waste heat of the exiting flue gas of the air preheater 2 can be recycled in this way.Boiler air-supply heater 8 will be from
The tow taste heat that the extraction of 4 exiting flue gas of the air-introduced machine comes is sent into the boiler 1 by 2 part of the air preheater
Burner hearth can play the role of directly saving fuel, and utilization ratio is very high；The outlet that another part passes through the air preheater 2
The raising of flue-gas temperature is converted to high-grade heat, and first smoke gas afterheat heat exchanger 31 can be by this part high-grade warm
Amount passes to other heat users, such as heats or heat the condensed water of steam turbine.To realize fume afterheat tow taste heat to
The conversion of high-grade heat and the step of fume afterheat recycle, and can improve the utilization ratio of fume afterheat, have relatively strong
Heat pump efficiency.Meanwhile the entrance flue gas temperature of the deduster 3 is reduced by first smoke gas afterheat heat exchanger 31,
So that the specific resistance of flue gas reduces, volume flow reduces, the efficiency of the deduster 3 can be improved, can also contribute to simultaneously
Remove partial vulcanization ingredient.
Certainly, 4 entrance of the air-introduced machine or outlet can be provided with third smoke gas afterheat heat exchanger (not shown), this
Kind mode benefit is that flue gas abrasion of heat exchanging device after dedusting is greatly decreased.
In a preferred embodiment, the air preheater 2 has been arranged in parallel the second smoke gas afterheat heat exchanger 21.Also
Be say second smoke gas afterheat heat exchanger 21 smoke inlet and outlet respectively with the smoke inlet cigarette of the air preheater 2
Road is connected with exhaust pass, that is, is provided with the bypass flue of the air preheater 2, and institute is arranged in the bypass flue
State the second smoke gas afterheat heat exchanger.Due to that 2 entrance wind-warm syndrome of the air preheater can be made to carry by boiler air-supply heater 8
Height, therefore the entrance high-temperature flue gas demand for entering the air preheater 2 is reduced, and the bypass flue and described second is arranged
Smoke gas afterheat heat exchanger 21 can make full use of high-grade heat, such as can give this part high-grade heat transfer to other heat
User, to further promote transformation efficiency and cascade utilization efficiency of the boiler smoke tow taste heat to high-grade heat, heat
Pumping action protrudes.
When the air-supply heater 8 is arranged in 6 entrance of pressure fan, the air-supply heater 8 may be configured as to divide
From setting (such as may be used and the forms such as lift or be detachably connected or overturn).That is the air-supply heater 8 with
The entrance of the pressure fan 6 can detach, and such purpose is：Blow described in the normal use heater 8 when, can make described
Air-supply heater 8 is tightly engaged into 6 entrance of the pressure fan.When summer environment temperature is higher, the air-supply heater 8 is to sending
When wind heating efficiency is poor, the air-supply heater 8 can be detached so that the air-supply heater 8 enters with the pressure fan 6
Mouthful at a distance, to reduce the entry resistance of the pressure fan 6.A kind of boiler smoke provided by the present invention is energy saving disappear it is white
Device, not only can abundant Mist heat recovering, but also have apparent heat pump effect, can be promoted recycling thermal energy grade with
Utilization ratio, while the efficiency of dust collection of electrostatic precipitator, desulfurizing tower desulfurization effect by the reduction of flue-gas temperature, can also be improved
Rate, reduces smoke evacuation moisture and pollutant carries, and reduces chimney and emits white cigarette phenomenon, reduces water consume, recovery section water, while playing section
Energy, environmentally friendly effect.
