| Abstract: | Working principles and technological characteristics of self-preheating economizer without low-temperature corrosion are described. Low-temperature corrosion of the economizer can be completely avoided by adding a boiler feed water preheater before economizer, where low-temperature BFW is heated by high-temperature BFW from economizer outlet as intermediate heat carrier, so the inlet water temperature of the economizer in low temperature section is higher than the dew point of off-gas. The economizer features simple structure, convenient arrangement, long service life, convenient operation and maintenance and low upkeep cost. It has been used in several sulphur-burning and pyrite-based sulphuric acid plants with good results. |
