Gas-gas waste heat recovery unit

Working Principle of Axial Heat Pipes:A heat pipe generally consists of a tube shell, capillary porous material, and working medium. The purified working medium is filled into the tube shell, which contains a capillary wick material and is evacuated to a high vacuum, then sealed.

One end of the heat pipe is the evaporation section, and the other end is the condensation section. When one end is heated, the working medium liquid in the capillary wick absorbs heat and vaporizes into steam. The steam flows to the other end, where it is cooled, releasing the latent heat of vaporization and condensing back into liquid. The liquid then returns to the evaporation section through the porous material under capillary force and is heated and vaporized again. This cycle repeats continuously, transferring heat from one end of the heat pipe to the other.

Features of Axial Heat Pipe Waste Heat Recovery Devices:Suitable for gas-to-gas heat exchange;When installed vertically, the heat flow direction is reversible, meaning whether one end of the heat pipe is the evaporation or condensation section depends on whether it is being heated or cooled;The internal pressure of the device can reach up to0.6MPa;The flue gas side and air side are separated by a partition to avoid cross-contamination;The waste heat recovery device can control the heat pipe wall temperature above the dew point, providing excellent resistance to low-temperature corrosion;Low investment, easy installation, simple maintenance, safe and reliable, with a comprehensive thermal efficiency of over85%. 

Applications:Waste heat utilization in the automotive industry,Waste heat utilization from boiler flue gas,Waste heat utilization in smelting furnaces,Waste heat utilization in kiln-type industrial processes,Waste heat utilization in the metallurgical industry,Waste heat utilization in the ceramic industry,Waste heat utilization in the glass industry,Waste heat utilization in the cement industry,Waste heat utilization in the textile industry
