Described accident burner chilled water tank is also connected with nitrogen cylinder, and nitrogen cylinder is used for inputting nitrogen, and accident burner chilled water tank and nitrogen cylinder are connected with the valve of control inputs nitrogen.When there is power outage, or in reserve pump starts interval time, open valve, high pressure nitrogen is filled with accident burner chilled water tank, guarantees that the cooling of burner remain valid, and guarantees normally to produce.
Operation principle of the present invention is as follows:
First be that cooling water in burner chilled water tank is forced into required pressure through pressure pump, then directly enter the accident burner chilled water tank of high point, by the liquid level of cooling water in flow control valve assurance accident burner chilled water tank, then cooling water enters the cooling jacket of burner through accident burner chilled water tank, prepares burner to carry out cooling; After burner is cooled, cooling water leaves cooling jacket and enters cooler, is admitted to burner chilled water tank after choke valve, and circulation goes round and begins again.
When normal operation, for guaranteeing cooling water temperature and the pressure stability of turnover burner, on cooling jacket, be provided with pressure and temperature sensor, in the time of can monitoring at any time the hypotony in the cooling jacket that enters burner, start standby pressure pump.
Described cooling water can be desalted water.
The invention has the beneficial effects as follows:
When cooling water system job insecurity state, the present invention can guarantee the normal work of accident chilled water tank, and the cooling of burner remained valid, and increased the reliability of whole system; Particularly at generation power outage or reserve pump, start in interval time, valve open, high pressure nitrogen is filled with accident burner chilled water tank, guarantees that burner Cooling system pipe internal pressure is greater than gasification furnace pressure, guarantee that the cooling of burner remain valid, guarantee normally to produce; In addition, the minimizing of valve and number of tubes, has also reduced maintaining cost.
