【Abstract】 Heat pipe boiler has advantages of high heat transfer efficiency, compact structure, low flow resistance, adjustable thermal resistance on both sides, reliable operation, convenient operation and maintenance, which makes it especially suitable to recovery of waste heat from the medium- and low- temperature gas. In order to save energy and reduce environmental pollution, Guixi Smelter made use of the heat pipe boiler to cool gas in the conversion system instead of existing SO3 cooler and cooling fan. This technique could recover waste heat at medium and low temperature and produce low-pressure saturated steam to reduce load of low-pressure boiler. It has produced 78 519 t steam at 1. 27 MPa in 8 months and saved 10 128 t standard coal. The economic benefits were significant.更多还原
