A natural gas steam generator is a mechanical device that uses natural gas as fuel to heat water into steam. 
It is a kind of gas steam generator, which is a mainstream product and occupies an important position. Its working principle is that the heat generated by natural gas combustion is first absorbed by the water wall through radiation heat transfer, and the water in the water wall boils and vaporizes, generating a large amount of steam into the steam drum for steam-water separation, and the separated saturated steam enters the superheater, and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and tail flue through radiation and convection, so that the superheated steam reaches the required working temperature.
The natural gas steam generator has the characteristics of low nitrogen environmental protection, automatic control, safety and reliability, energy saving and high efficiency. Among them, low nitrogen environmental protection is because natural gas is one of the three major clean energy sources recognized by the country, and the fuel combustion is sufficient, reducing exhaust emissions, and meeting the national environmental protection indicators. The automatic control is because the gas steam generator adopts an intelligent control system, which can realize automatic control, with flame detection, pressure detection, overpressure protection, water shortage protection, overheating protection automatic alarm and other functions, without the need for special personnel on duty.
In addition, natural gas steam generators have a wide range of applications in all walks of life, such as disinfection and sterilization, cooking, bathing and sauna, road maintenance, hot water in hospitals and schools, bathing water, etc. At the same time, safety should be paid attention to when using natural gas steam generators, and they should be used within the scope of the state's exemption from boiler use certificates, so as to ensure that the equipment is kept away from flammable and explosive materials and humid environments.
