The environmental protection advantages of gas boilers stand out among many boiler models. Due to the high efficiency of the boiler and the particularity of the fuel, there are many protection measures for operation. So what protection systems are there for environmentally friendly gas boilers? What is the control device? Let's learn about it with XinLi boiler.

Gas boiler protection system

　　Gas-fired environmental protection boilers must be equipped with water level protection, pressure protection and temperature protection, etc., each of which is as follows:

　　1. Water level protection. Whether the water level of the gas boiler is normal or not has a great impact on the boiler. The water level protection system can avoid major accidents caused by the lack of water and dry burning of the boiler.

　　2. Pressure protection, gas boiler pressure protection can make the pressure of the entire boiler exceed the rated value and need interlocking protection. For the overload pressure safety valve, it will automatically start to release the pressure, and automatically shut down when the pressure is restored to normal to prevent the boiler from exploding. Danger.

　　3. Temperature protection. Temperature protection is an important program during the operation of the boiler. It is particularly important for the temperature adjustment and protection of the entire boiler. The commonly used temperature protection device for the furnace is a bimetal temperature controller.

Gas boiler control device

　　The gas boiler control device has two major systems: a burner and an electric control cabinet. The successful setting of the burner can automatically and reasonably adjust the air to fuel ratio, promote full combustion of fuel, and reduce nitrogen oxide emissions. In addition, it is a PLC control system and touch screen display control equipment. , Set boiler operating parameters to realize unattended operation management.
