Huatai gas steam boiler is a heat 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. The water is continuously heated in the pot (drum) by the energy released by the combustion of the gas fuel in the furnace, the temperature rises and steam under pressure is generated. Since the boiling point of water increases with the increase of pressure, the pot is sealed and the water vapor Expansion inside is limited and pressure is generated to form thermal power widely used as an energy source.

The boiler is mainly composed of two main bodies, the shell and the furnace, and accessories to ensure its safe, economical and continuous operation, instrument accessories, automatic control and protection systems. This kind of boiler is a drum-type boiler with a water-cooled wall. Two return pyrotechnic pipes are arranged in the left and right partitions of the drum, and are turned back in the front smoke box at the front of the drum. Between the drum and the lower connecting box, there are descending pipes and water-cooled wall pipes, 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 drum, the water-cooled wall tube and the pyrotechnic tube.

The steam boiler is composed of a series of equipment, which can be roughly divided into main components and auxiliary equipment.
