(1) there was a pop or a pop.

(2) the furnace was originally a negative pressure combustion, into a positive pressure combustion, coal fired water heaters and furnace smoke and steam out.

(3) the feed water flow becomes abnormal and is larger than the steam flow.

(4) the water level cannot be maintained within the normal range and the air pressure decreases.

(5) smoke exhaust temperature in jiangdu, the temperature in the chamber of the coal-fired water heater decreases.

(6) the load of the induced fan increases and the current increases.

Steam boiler, the correct treatment measures of boiler tube burst are:

If the pipe burst is not serious and the water level can be maintained, the coal-fired hot water heater can reduce the load in a short period of time to maintain the operation of the boiler, and stop the boiler after the standby furnace is started.However, if the water level cannot be maintained, the furnace should be shut down urgently. The coal-fired water heaters should not be shut down, but the induced draught fan should not be shut down.
