Starch industry how waste heat utilization and energy efficiency? Starch industry generally use steam boilers, exhaust gas temperature is higher generally around 250 degrees, the flue gas heat is much room, we put some heat recycling can get a good economic benefits. I carry too many companies use, summed starch factory waste heat recovery scheme applicable two: one is the use of flue gas waste heat to generate steam for production use, the other is producing hot water for boiler feed water and improve the thermal efficiency of the boiler. Here we introduce a method for generating steam heat recovery steam generators --- heat. Heat recovery steam generator is mounted directly in the boiler flue original position, take full advantage of waste heat, no other energy sources, economic benefit. Compact heat recovery steam generator, small footprint, less investment in infrastructure. After the installation of a heat recovery steam generator production generally 3-8 months to recover the full investment. Heat recovery steam generator heat transfer element main superconducting heat pipe, heat pipe having the good isothermal properties, resulting in no masonry natural ventilation resistance when dirt and thermal conductivity, and always maintain a good heat transfer efficiency, boiler steam generator does not affect the boiler or furnace work, and therefore has the advantage of safe and reliable. Heat recovery steam generator principle: The device is installed in the boiler flue location, use heat pipe technology to heat recovery. Characteristics of heat pipe heat absorbing efficiency is fast, is a heat transfer element having high conductivity properties, which closed vacuum envelope by the working fluid evaporation and condensation to transfer heat, with a high thermal conductivity, good isothermal, hot and cold sides of the heat transfer area can be arbitrarily changed, long-distance heat, temperature-controlled series of advantages. Steam generated by the steam boiler can be directly incorporated into the pipeline for production use.
