| Abstract: | Analyzes a mechanism of low temperature corrosion and ash accumulation in heater and points out that acid dew point and ash accumulation are major factors restricting temperature reducing in smoke exhaustion. Puts forward that such measures as using heat tube air preheater, control metal's wall temperature, strengthening treatment to fuel desulfurization and developing low temperature anti-material shall be taken to reduce ash venting temperature and raise heater's efficiency. |
