Coal-fired steam boiler refers to the coal heat after the conversion of steam. The furnace body is equipped with pressure gauge, safety valve, water level gauge and other instrument valves, the pressure gauge shows the pressure of the boiler, at any time to monitor; The safety valve opens automatically when the boiler reaches a certain pressure, so that the boiler can operate safely and reliably. Both sides of the furnace are densely covered with light tube and water-cooled wall tube, the design structure is reasonable and compact.
The heating area is large, the flue gas flow is long, the heat transfer effect is good, the exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical.
