Description
Technical field
The present invention relates to a kind of biomass boiler steam heater, belong to biomass boiler field.
Background technology
The Air Leakage that biomass boiler air preheater pipe dust stratification, corrosion cause always perplexs the difficulty of biomass power generation enterprise
What topic, dust stratification and corrosion caused leaks out, and causes air-introduced machine load to increase, decreases the air output needed for boiler combustion, reduce
Efficiency of combustion, load band is not enough.
Generally after boiler is gone into operation 1 year, check and find two boiler air preheater pipe dust stratifications and heavy corrosion, cause boiler
Inleakage is big, and the air quantity affecting boiler adjusts and boiler combustion.Dust stratification position is mainly distributed on low-temperature zone air preheater both sides, every time
Blowing out will be rinsed；Air preheater pipe burn into air leakage parts is low-temperature zone import cold wind section.
After there is problem above, boiler high and low temperature section air preheater pipe is removed by technical staff, is carried out by air preheater the most more
Changing, tube sheet and pipe are redesigned by boiler factory, the size constancy of pipe, the external radiation enamel of pipe, and the thickness of enamel exists
0.5 millimeter, the two ends of pipe use graphite annulus to seal.After boiler air preheater is replaced by enamel pipe, eliminate air preheater pipe
Leak out, can only say and alleviate dust stratification, but the most really solve the problem of ash deposits corrosion, the service life of air preheater pipe also only two
Year, change the most one by one after 2 years.The expense of every pipe about 55 yuan, renewal cost about 35 yuan, our separate unit stove low temperature
Section air preheater pipe totally 2916, high temperature section totally 3939.Normal pipe is changed and is concentrated mainly on low-temperature zone, and we are total to up to now
Change enamel pipe 1673.If the expense that separate unit boiler low-temperature section pipe is all changed is about at 270,000 yuan.Add every
Secondary because the liter blowing out that air preheater problem causes is lost, it is seen that air preheater problem is to affect the key subjects that we run.
Summary of the invention
The present invention provides a kind of biomass boiler steam heater, not only improves air intake and the temperature of air-out, improves pot
The heat exchange of stove and combustion efficiency so that superficial dust speed is greatly alleviated, and effectively alleviate back-end ductwork and remove
The corrosion of dirt device.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of biomass boiler steam heater, described biomass boiler steam heater includes header, support, finned tube and adds
Heat pipe, described header is supported by support, described finned tube and add heat pipe and be arranged in casing, described in add heat pipe serpentine-like
Shape is sequentially arranged, and forms 39 rows and stagger successively arrangement, and second row adds heat pipe, the 6th row adds heat pipe, the tenth row in removing
Add heat pipe, the 14th row adds heat pipe, the 18th row adds heat pipe, the 22nd row adds heat pipe, the 26th row adds heat pipe, the 30th
Row adds heat pipe and the 34th row adds heat pipe, and remaining adds and is respectively sleeved on finned tube on heat pipe；
As present invention further optimization, described finned tube uses pressed-steel aluminum composite helical fin pipe；
As present invention further optimization, described in add heat pipe and use metallic aluminium or metallic copper to make；
As present invention further optimization, described header is respectively arranged at two ends with inlet header and outlet header；
As present invention further optimization, described inlet header is equipped with Pressure gauge and thermometer, and described outlet header is equipped with row
Dirty valve.
By above technical scheme, relative to prior art, the method have the advantages that
The present invention sequentially arranges by adding the serpentine-like shape of heat pipe, and forms 39 rows and stagger successively arrangement, second row, the 6th
Row, the tenth row, the 14th row, the 18th row, the 22nd row, the 26th row, the 30th row and the 34th row add heat pipe
On be respectively sleeved on finned tube, compared with the adding and be all socketed with finned tube on heat pipe of serpentine shaped in prior art, the application subtracts
Lack by temperature area, not only improved air intake and the temperature of air-out, improve heat exchange and the combustion efficiency of boiler so that superficial dust
Speed is greatly alleviated, and effectively alleviates the corrosion of back-end ductwork and cleaner unit.
