1. and supplementing deoxygenated water to the buffer tank while the gasification system establishes water circulation.
2. And after the liquid level of the buffer tank is established, starting a feed pump, and feeding the condensate to a washing tower tray after passing through a low-pressure steam heater.
3. After the stable condensate passes through the low-pressure steam heater, low-pressure steam is used.
4. Circulating water is put into the cooler.
5. After the liquid level is established in the condensate separating tank, a pressure pump is put into the condensate separating tank, the condensate separating tank enters a sand filter through a cooler, and the condensate separating tank enters a buffer tank under the action of pressure.
6. And when the differential pressure of the sand filter reaches a certain value, starting the backwashing water pump, and backwashing the sand filter by using the condensate of the buffer tank. And fine ash generated by back flushing enters a settling tank for settling.
