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.
Description:
Most of utility boiler's exhaust gas temperature is higher 20~30ºC than design temperature. Therefore, adding lower temperature economizer at utility boiler can decreasing the
Boiler exhaust gas is a kind of useful source, therefore, we can use new technology equipment to reduce exhaust gas temperature. Flue gas lost is a part of boiler's thermosteresis, which is about 5% to 12%. It's 60% to 70% of the total heat loss. Exhaust gas temperature increase 10ºC will lead to flue gas lost increasing 0.6% to 1.0% and increase 1.2 to 2.4g/kwh coal used.
Reducing exhaust gas temperature has important signification for energy conservation and emission reduction. Installing lower temperature economizer at the end of boiler real smoke channel increase exhaust waste gas recovery, increasing generating capacity,reduce water consumption of desulfurization and protect chimney.
Features:
-
- The equipment made of H-type pin tube which has high heat transfer efficiency, compact structure, lower soot formation, and higher exhaust heat gas recovery efficient.
- Smoke entrance designed by XIAN Jiaotong University. The smoke uniform enters the equipment case to decreasing anti-attrition.
- The bottom of smoke content assembly unit is making by Sulfuric acid resistant steel that increasing the durable years.
- There is 800-900mm maintaining space between lower temperature and high temperature transfer tank, which helps reduction become more and more convenience.
- The equipment designed by separate modular that let installation and operator become easily and efficient.
Advantages:
- Reliability. All the design parameter will follow actual operation.
- Affordable. The reasonable system design will decrease equipment investment.
- prioritization scheme. The boiler system and steam turbine system's description, we can improve seam turbine's water in taking and backwater location to increasing exhausts waste gas recovery frequency.
- safety. It will keep reasonable control on the metal wall surface temperature and avoid smoke gas dew-point.
- The equipment made of H-type pin tube which has high heat transfer efficiency, compact structure, lower soot formation, and higher exhaust heat gas recovery efficient. There is 800-900mm maintaining space between lower temperature and high temperature transfer tank, which helps reduction become more and more convenience. The bottom of smoke content assembly unit is making by Sulfuric acid resistant steel that increasing the durable years. The service life period is more than 10 years.
