That is applied at present in fired power generating unit is very extensive, but its low-temperature corrosion, blocks and the problems such as bigger than normal of leaking out annoyings always
Engineers and technicians.Prevent that low-temperature corrosion of air preheater, the main method blocked from being by thermal wind sensor and warm wind at present
Device improves the entrance cold wind temperature of air preheater, so as to improve air preheater cold-end air hardware temperature, makes its temperature
It is higher than the acid dew point of flue gas as much as possible, the burn into for reducing air preheater blocks tendency, extends its life-span.
The shortcomings that above method, can only could be carried out during the longer or overhaul in the unit outage time once steam air heater damage
Change, thus equipment operation risk increases；And thermal wind sensor device sends back to the hot blast that extraction is exported from air preheater
The entrance of pressure fan, these hot blasts pass through air preheater after being mixed with cold air, fans entrance air quantity can so increased,
So that blower fan power consumption increases, and as the increase of thermal wind sensor amount, the power consumption of blower fan increased dramatically, increase considerably
Operating cost.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of simple, practical, efficient burn into for reducing air preheater
The reduction for blocking the rotary regenerative air preheater of tendency is leaked out anti-blocking ash system and method.

There is the second valve, second valve is located at blower fan and flue gas recirculation is divided between storehouse.
The reduction of the rotary regenerative air preheater of the present invention is leaked out anti-blocking grey method, including:Utilize swinging air preheat
The flue gas in the gas approach air channel of device will rotate the accumulation of heat member into flue gas storehouse to what is rotated out of by a wind cabin or secondary wind cabin
Part heats.
The reduction of the rotary regenerative air preheater of the present invention is leaked out anti-blocking grey method, wherein, it is described to by a wind cabin or
What secondary wind cabin rotated out of, the heat accumulating element that will be rotated into flue gas storehouse is heated to be to being rotated out of by a wind cabin or secondary wind cabin
, the bottom cold end heating into the heat accumulating element in flue gas storehouse will be rotated.
Technical scheme can control air preheater cold-end air heating surface wall surface temperature in the reasonable scope, no
Low-temperature corrosion and dust stratification are only alleviated, extends the service life of air preheater, and fans entrance air quantity will not be increased, from
And avoid the increase of blower fan power consumption.
Technical scheme may replace steam air heater and thermal wind sensor device, while simpler than both of these approaches,
Practicality, air preheater anticorrosion, blocking-proof result are more preferable；The carrying for reducing air preheater simultaneously is leaked out and the leakage of side air
Wind so that the air leakage coefficient of air preheater is greatly reduced.
Due to the presence in flue gas recirculation system so that originally the sky of fume side is brought in First air or Secondary Air rotation into
Gas, flue gas recirculation system is entered, finally import First air or Secondary Air in hot junction, thus leaked out substantially without carrying.
Simultaneously because the presence of flue gas recirculation system, the air of fume side is leak into by First air or Secondary Air, is become by again originally
Circulating flue gas divides the flue gas in storehouse, thus reduces air preheater side air and leak out.
