Gas-fired steam boiler is a kind of thermal energy conversion equipment that uses natural gas, liquefied gas, city gas and other gas fuels as fuel, and the heat released in the furnace heats the water in the boiler and vaporizes it into steam. , Medicine and other industries have applications. How does the gas-fired steam boiler complete its normal operation? Many users are very curious about this question, Zhengzhou Fangkuai Boiler Factory is here to answer it for everyone for free.
The water in the pot (drum) is continuously heated by the energy released by the combustion of the gaseous fuel in the furnace, and the temperature rises and generates pressurized steam. Because the boiling point of water rises with the increase in pressure, the pot is sealed and steam The expansion inside is restricted to generate pressure to form thermal power (strictly speaking, the steam of the boiler is formed by heating water in the drum at a constant pressure to saturated water and then vaporizing), which is widely used as an energy source.
The boiler is mainly composed of two main bodies: the shell and the boiler, the accessories to ensure its safe, economical and continuous operation, the auxiliary equipment of the instrument, and the automatic control and protection system. This kind of boiler is a drum-type boiler with a water-cooled wall. Two return pyrotechnic tubes are arranged in the left and right sections of the drum, and the front smoke box at the front of the drum is folded back. Between the drum and the lower connecting box, there are a downcomer and a water-cooled pipe, which constitute the frame of the combustion chamber. There is a steam-water separator on the upper part of the drum to reduce the water brought out by the steam. The heating surface of the pot body is the lower part of the pot, the water-cooled wall tube and the pyrotechnic tube.
