Description
Technical field
The present invention relates to a kind of economizer, and in particular to a kind of economizer of variable cross section regulation, belongs to boiler for producing neck
Domain.
Background technology
Economizer be arranged in the flue of boiler body rear portion for heating boiler feed water, reduce the convection current of flue-gas temperature by
Hot face.Current large-scale centralized heat supplication and consumption homogeneous solution-type reactor is more to be all disposed with economizer, due to In The Initial Period Of Heating and latter stage thermic load
Relatively low phenomenon generally existing, individual user does not reach boiler economic load index there is also actual heating demand in a short time is relatively low,
This can all cause boiler rear portion heating surface economizer dust stratification, air preheater dust stratification condensation, or even cause sack cleaner condensation stifled grey,
Directly affect safe operation of the boiler.
The content of the invention
The present invention is relatively low in the presence of actual heating demand in a short time to solve existing economizer, does not reach boiler economic load and refers to
Mark, this can all cause boiler rear portion heating surface economizer dust stratification, air preheater dust stratification condensation, or even cause sack cleaner condensation stifled
Ash, the problem of directly affecting safe operation of the boiler, and then propose a kind of economizer of variable cross section regulation.
The present invention adopts the technical scheme that to solve the above problems：The present invention include economizer main body, multiple dividing plates and
Multiple regulation pipe valves, multiple dividing plate side by side parallel are arranged in economizer main body, and a flue gas is constituted between two neighboring dividing plate
Passage, the porch of each exhaust gases passes towards flue gas approach axis is equipped with a regulation pipe valve.
The beneficial effects of the invention are as follows：The province's coal for participating in heat exchange can effectively be adjusted by being adjusted using variable cross section after economizer
Device heating surface area and flue gas circulation area, are effectively adapted under heating boiler long period underrun operating mode, back-end surfaces
Low-temperature heat exchange, exhaust gas temperature are low, exhaust gas volumn is few, cigarette is fast low, easy in accidents such as back-end surfaces formation dust stratification, condensation, corrosion
Generation.Safe operation to heat supply user brings reliable regulation to ensure；The present invention is utilized and is arranged in economizer passage
Dividing plate blocks a multigroup economizer flue constituted with the multigroup of economizer smoke inlet passage is arranged on, and is born according to different boilers
Lotus is turned on and off different pipe valves, it is ensured that higher by economizer cigarette speed.The portion that the pipe valve and buffler of closing are separated out
Divide economizer not to be heated, equivalent to the heating surface area of economizer is reduced, reduce economizer flue gas flow area, not only play cigarette
Gas adjustment effect, also corresponds to water by-pass and plays working medium side adjustment effect.
