Guide: The working principle of the gas boiler: the fuel burns, and the water in the boiler is heated to turn into high-temperature hot water or steam. The working process of the gas boiler is the process of converting the chemical energy of the fuel into heat energy. The characteristics of gas boilers are energy saving, environmental protection, safety, and help industrial production.

The working principle of the gas boiler: the fuel burns, and the water in the boiler is heated to turn into high-temperature hot water or steam. The working process of the gas boiler is the process of converting the chemical energy of the fuel into heat energy. The characteristics of gas boilers are energy saving, environmental protection, safety, and help industrial production.

1. The operation system of gas boiler is mainly divided into flue gas system and water system:

  1. Flue gas system: fuel combustion-furnace-two-pass smoke pipe-three-pass smoke pipe-economizer-condenser-flue;

  2, water system: boiler raw water-softened water tank-boiler-steam or water enters the steam or heating pipeline;

gas boiler

2. Auxiliary equipment

  The auxiliary equipment of gas boiler mainly includes control cabinet, burner, water pump, chimney, water treatment, sub-cylinder, economizer, condenser, softened water tank, boiler water sampler, etc.

  1. Control cabinet: The control system is the core of the boiler operation. The boiler operation data monitored by each instrument will eventually be summarized in the control system. After the control system compares and analyzes the data, a new control command is made to change the operating pressure and water level of the boiler. , The temperature is controlled within a safe range.

  2. Burner: The burner and the corrugated furnace form the combustion equipment of the boiler. The burner mixes natural gas and air in a reasonable ratio for thorough combustion to heat the water in the boiler.

  3. Water treatment equipment: remove calcium and magnesium cations in the boiler raw water, reduce the hardness of the water, avoid boiler fouling, and extend the service life of the boiler;

  4. Energy saver and condenser: energy-saving equipment for boilers, which increases the inlet water temperature and lowers the exhaust gas temperature.

Gas-fired boilers have a wide range of uses, including food, chemical, pharmaceutical, building materials and other industries. They have a wide range of uses. To ensure that the boiler runs in the best conditions, it is necessary to ensure that the selection is reasonable.
