Heat pipe type heat recovery device improves boiler efficiency

Langfang Jinsheng Energy Saving Technology Service Co., Ltd. recently successfully developed a heat pipe type waste heat recovery device that can reduce the exhaust gas temperature of oil-fired gas boilers to 90°C and improve the boiler efficiency by about 5%, and promotes its application in petrochemical enterprises.

According to reports, the boiler exhaust temperature directly affects the economic efficiency of the boiler unit and the safety of the tail heating surface. Choosing a lower exhaust temperature can reduce the exhaust loss of the boiler, help to improve the boiler thermal efficiency, save energy and reduce the boiler operating costs, but the exhaust smoke temperature reduces the heat transfer temperature and pressure of the flue gas and the working fluid in the heated surface of the tail. Reduced, heat transfer surface increases, metal consumption and initial investment in equipment increase. In addition, the exhaust gas temperature is too low to cause the condensation of steam in the smoke, so that the low temperature heating surface corrosion plugging, so most of the boiler exhaust temperature is about 200 °C, the use of heat pipe heat recovery can comprehensively solve these problem.
