Description
Technical field
The present invention relates to a kind of finned coal saving device.
Background technology
Economizer is an important component of boiler, and its operation principle is relatively low using boiler back end ductwork temperature is flowed through
Flue gas boiler feedwater heating surface, in favor of improve boiler the thermal efficiency, save the energy.But traditional light pipe type saves
Coal device needs large volume of economizer to reduce exhaust gas temperature because heating surface is small；Further, since the soot particle in flue
Impact and cutting force can be produced to economizer pipeline, cause economizer wear and leakage, cause economizer can not normal use.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of coal saving device, solves economizer surface in the prior art
Small, economizer leakage easy to wear technical problem.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of coal saving device, including import header, outlet header and be connected to the import header and outlet header it
Between coiled pipe, be provided with fin on the outside of the coiled pipe.
Preferably, in above-mentioned coal saving device, the array axially outside of the coiled pipe is provided with multiple fins.
Preferably, in above-mentioned coal saving device, the axis of the vertical coiled pipe of plane where each fin.
Preferably, in above-mentioned coal saving device, the joint of each fin and coiled pipe coordinates the coiled pipe
Outer surface be arranged to circular arc.
Preferably, in above-mentioned coal saving device, the multiple fin is symmetricly set in the both sides of the coiled pipe.
Preferably, in above-mentioned coal saving device, the fin is connected to the outside of the coiled pipe by welding manner.
Preferably, in above-mentioned coal saving device, the material of the fin is steel.
Preferably, in above-mentioned coal saving device, described coal saving device also includes catalyst bracket and is fixed on institute
State the catalyst module on catalyst bracket.
The beneficial effect of the finned coal saving device of the present invention：The finned coal saving device in coiled pipe both sides by increasing
Rectangular fin, so as to extended surface, heat exchange efficiency is improved, and because fin acts on, the air-flow in flue can be made to be formed
Stream, has simple for structure, efficiently, improves wear-out life, the advantages of avoiding economizer leakage.
Brief description of the drawings
