Qingdao Kaineng Boiler Equipment Co. ,Ltd. is located at Qingdao China. We are the high-tech enterprise in the professional manufacturing submerged arc furnace waste heat boiler, generator stack gas coal economizer, generator group waste heat boiler. Our company is mainly manufacturing flue gas waste heat boiler, low temperature economizer, fuel gas boiler, needle tube, the H fin tube energy conservation and environmental protection products.
KNLW serious exhaust gas boiler is special design for exhaust gas heat recovery of oil&gas fired generator groups.the boiler use the threaded pipe as the heat transfer component.the pipe has the thread line in the internal wall of the pipe.the exhaust gas will be swirling during going through the pipe.this will reinforce the heat transfer and reduce the heat transfer area to make the size and weight smaller.the boiler has the advantage of simple structure ,high efficient,long running life,safety and convenient maintain.every exhaust gas boiler is composed of inlet flue gas case,outlet flue gas case,screwed pipe,smoke-recovery chamber and its accessory.
The exhaust gas boiler has two kinds:horizental and vertical.the circulation style is nature circulation.the boiler body has the space for the seperation of steam and water.
Feature of exhaust gas boiler:
1,the boiler use pin tube as heat transfer component,which can increase heat transfer area 7-8 times,raise coefficient of heat transfer 2 times.So the heat transfer efficiency is raised 14 times.
2,the boiler has the ability of self-clean.the gas flow become a strong turbulence during going through the pin tube,which make the dust&ash difficult to accumulate on the tube.
3,the basic invest of the boiler is only 50-70% of the ordinary boiler,cheap and high cost performance.
Boiler advantage:
- High heat transfer efficiency. The welding fusion rate of fins with steel pipes can reach up to 95%.
- low contact resistance, good heat transfer performance.
- Low flow resistance
- Less dust
- Less wear and tear
- Small size and light weight
