Heat pipe air preheater The device utilizes the waste heat boiler flue gas temperature waste or industrial waste heat is used to produce hot water boiler make-up air or process using hot air, flue gas can be reduced to 170 ℃ -140 ℃. Type: Non-standard rated flue gas volume 2500Nm3 / h-37500Nm3 / h works using finned heat transfer, heat transfer efficiency, compact structure, small size; anti-dew point corrosion, anti-fouling; furnace equipment have kept clean? Gray smoke flow capacity and equipment of small resistance does not increase the load induced draft fan; completely separated from the flue gas and water vapor side, safe and reliable equipment; a high degree of automation equipment. Heat pipe heat recovery devices are small, but the long life of ordinary heat 1/3: The heat pipe heat recovery unit for more than 10 years of service life, low maintenance costs is simple. Energy efficiency is good: large industrial furnace efficiency can be increased by more than 10% of small and medium oil, gas, coal-fired boiler efficiency can be increased up to 5% -10% energy saving. The payback period is short: the general 3-6 months can recover the full investment. Energy conservation principle of heat pipe air preheater to heat pipe as the core heat transfer components, high temperature gas erosion Heat Pipe end, the heat pipe cooling medium evaporates into a gas to end the flow of the cooling side condensing heat, the air is heated. Hot air through the pipe for boiler makeup air. Performance advantages 1, cold and hot fluids in heat pipe outflow over, both sides can be used to strengthen the fin, heat transfer efficiency, compact size, pressure drop, low pressure loss, thus saving power consumption of the blower and induced draft fan . 2, the hot side of the heat pipe (gas side) and the cold side (air side) are separated using a partition, a reliable seal between the heat pipe and a separator. Thus the possibility of leakage between the air and the flue gas is very small, reducing the possibility of air leakage from the overall structure.
