The natural gas steam boiler adopts a fully automatic intelligent control system, uses continuous water supply, has the functions of high temperature, high pressure, low water level alarm, and shutdown of the boiler. It has safe and stable operation and long service life. What is the structure and principle of a natural gas steam boiler, I will give you a brief introduction. 1. Natural gas steam boiler structure

　　The main components of the natural gas steam boiler include the furnace bladder, economizer, drum, combustion equipment and frame. The function of the furnace is to ensure that the boiler fuel burns; the economizer can use the heat of the tail flue gas to continue heating, saving gas consumption; the boiler drum is the main body of the boiler, which can store soda and water; the combustion equipment inputs the gas and the air required for combustion into the furnace .

　　In addition to the main components, the natural gas steam boiler is composed of multiple parts, including fuel preparation system, wind and smoke system, electric control system, steam and water system, combustion system, water treatment system, and all parts are closely coordinated and operated together.

2. Principle of natural gas steam boiler

　　Natural gas steam boiler is a heat energy conversion device that uses natural gas as fuel, burns the heat in the furnace, heats the water in the boiler, and vaporizes it into steam. The water in the pot (drum) is continuously heated by the energy released by the combustion of gaseous fuel in the furnace, and the temperature rises and produces 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.

　　When using a natural gas steam boiler, first ensure that the boiler's water is properly treated. Whether it is contaminated water, or water with high hardness and unsuitable pH, it will affect the service life of the boiler and may cause accidents. Therefore, the heating water must be pre-treated when it is fed into the steam boiler. The temperature of the input water should be kept above 20°C and as close as possible to the temperature of the furnace body. This is good for improving the efficiency of the boiler and saving energy consumption.

The above briefly introduced the problem of "natural gas steam boiler structure and principle", I hope it will be helpful to you. Xinli Boiler has been committed to the boiler industry for more than 30 years. It is good at production and heating boiler selection and technical support. Welcome to consult.
