Description

Technical Field

[0001] The utility model relates to the technical field of natural gas boilers, in particular to energy-saving natural gas boilers. Background Art

[0002] A natural gas steam boiler is a type of pressure vessel. A natural gas steam boiler is a heat energy conversion device that uses natural gas as fuel. The heat released by the combustion in the furnace heats the water in the pot and vaporizes it into steam. The water in the pot (boiler drum) is continuously heated by the energy released by the combustion of the gas fuel in the furnace to increase the temperature and generate pressurized steam. Since the boiling point of water increases with the increase of pressure, the pot is sealed, and the expansion of water vapor inside is restricted, generating pressure to form thermal power. Strictly speaking, the water vapor in the boiler is formed by heating water at a constant pressure in the drum to saturated water and then vaporizing it. It is widely used as an energy source.
