Boilers need emergency shutdown under what circumstances? Emergency shutdown means the immediate cessation of the supply of fuel and air to the supermarket atmospheric pressure boiler dealer, to quickly stop its operation.

When the water level below the water level gauge visible water level or higher than the maximum permissible level, namely boiler severe water shortages or severe filled with water. Main feedwater pipe, main steam pipe, when the reheat steam explosion. Superheater tube bursting, or blasting waterwall tubes can not be maintained when the drum water level. When knocking occurs in the furnace or the flue, the equipment was heavily damaged, and when the furnace fire. Rear of the boiler flue secondary combustion occurs, so that a sudden increase in exhaust gas temperature when abnormally. All suction blower or a rotary air preheater stops running. After the action is not safe seat, and steam pressure drops, the turbine steam temperature to the extent permitted time. Operating pressure exceeds the vapor pressure of the safety valve, safety valve does not operate at the same time, the exhaust steam space and a door, can not be opened when the two bypass. When all the water level gauge water level gauge damage and loss of all instructions. Other irresistible endanger the personal safety of the equipment when the accident occurred.

According to the above analysis, the salt content must be strictly controlled supermarket atmospheric pressure boiler dealer water, taking care to control the steam soluble salt with water and saturated steam, thereby to obtain the desired steam boiler cleaning. In order to reduce the saturated steam of water, moisture separator should establish good conditions and improve the use of the water separation device. In order to reduce the dissolved salts steam, may be appropriately controlled alkalinity boiler water and steam cleaning apparatus; furnace in order to reduce the amount of salt water may be employed to improve the quality of feed water, a steam boiler blowdown and other methods using segment.
Exhaust gas temperature of the heat loss is heat loss of a primary gas supermarket atmospheric pressure boiler dealer, it is mainly dependent on the temperature of exhaust gas with an excess air ratio. In operation, perhaps you want to make sure that decline in the exhaust heat is lost completely incinerated under conditions to improve boiler burning power, boiler exhaust gas temperature too high can lead to thermal power boiler decline.
