Flue gas waste heat recovery device Features: long service life (15 years), mainly composed of composite fin tubes with high thermal conductivity and strong acid corrosion resistance; High fin to fin ratio, compact structure, small size, light weight, easy to install, and can be used in combination; The energy-saving effect is obvious and the investment return period is short (1-2 years); Users can specify any material (optional materials: steel aluminum composite, ND steel, stainless steel, carbon steel)

The use efficiency of oil fired, gas fired and coal-fired boilers is about 70%, and flue gas heat accounts for the majority of wasted heat. This part of heat can be recovered by the flue gas waste heat recovery device, which can increase the boiler water inlet temperature, air blast inlet temperature or directly generate steam for production and domestic use. The transformation of the boiler is simple. The flue gas waste heat recovery device produced by Kuanxin Company can be installed and replaced in the first section of the boiler flue. It can be installed arbitrarily without changing the original equipment status. At the same time, full automatic control can be added to realize unattended. It has the advantages of safety, environmental protection, energy saving and consumption reduction.

The utilization efficiency of waste heat recovery of industrial oil, gas and coal-fired boilers is about 70%, and flue gas heat accounts for the majority of wasted heat. Generally, the exhaust gas temperature at the tail of steam and hot water boilers is more than 280~350 ℃. The boiler economizer can recover this part of heat to increase the boiler water inlet temperature, air blast temperature or directly generate steam production and domestic gas.
