- Abstract:
- This paper discusses the design optimization measures of the sludge incineration project by analyzing the commissioning experience based on the second phase project of Shanghai Shidongkou sludge treatment plant. The ratio between semi-dry sludge and dewatered sludge can be adjusted according to the fluctuations of sludge calorific value and moisture content, and a homogenizing function can be added in the sludge receiving facility before furnace, so as to stabilize the operation conditions of the incinerator. A centralized storage facility for semi-dry sludge can be set up between drying and incineration processes to improve the flexibility and stability of project operation, also reduce the difficulty of logical control for the production line. The sludge conveying system should be simplified as much as possible. The capacity allowance of the sludge conveying system should not be too large. Moreover, it is necessary to consider the working condition caused by sludge property change after the backmixing of dry and wet sludge before furnace.
