If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur. This may lead to problems elsewhere in the steam system, such as:
The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.
The safety valve of the boiler refers to the valve on the top of the boiler near the boiler control room. The function of the safety valve is to be opened automatically to exhaust the steam and restore the pressure when the boiler pressure exceeds the specified valve, so as to ensure the safety of boiler pressure-bearing components and steam turbines.
According to the power of water or steam circulation, boilers can be divided into natural circulation boilers, forced circulation boilers, once-through boilers and combined circulation boilers.
The quality of boiler feedwater is an important determinant of safe boiler operations and it should be monitored to maintain the quality within safe working limits. Boiler feedwater is treated to protect the boiler from two basic problems: the buildup of solid deposits on the interior or water side of the tubes, and corrosion.
If the hot oil pump of the fully automatic thermal oil heater is suddenly damaged and stops working during the operation, the boiler circulation will be blocked. If the fuel is still burning to make the oil temperature keep rising, it will cause the coking of the hot medium oil which is easy to cause a fire. If the fully automatic thermal oil heater catches fire due to the power cut during the operation, the boiler operator should quickly put out the fire in the furnace to stop the fuel from burning, and blow a large amount of cold air into the furnace to lower the temperature.
