As the current energy-saving, environmentally friendly and high thermal efficiency furnace type, gas-fired boilers have basically replaced coal-fired boilers with high pollutant emissions in the past, but this also requires daily maintenance of gas-fired boilers, so that the boilers always maintain better performance. What are the key components of gas boilers to be maintained? What should be paid attention to in maintenance? Let's learn about it with XinLi boiler.

Key maintenance parts for gas boilers

　　The important components of gas boilers are fans, water pumps, proportional valves, controllers, heat exchangers and burners, etc. The maintenance of each component is as follows:

　　1. The fan, the boiler fan assists the full combustion of the boiler fuel. Daily cleaning of the boiler fan should be done on the outside, and the internal dust should be cleaned. At the same time, check whether the fan blades are worn or cracked, and repair or replace them.

　　2. Water pumps and boiler feed water pumps are related to the safe and stable operation of the boiler. Daily scientific maintenance volumes should be established, such as replacement of parts and enhancement of boiler lubrication system maintenance.

　　3. Valves are important pipeline accessories of boilers, which are mainly used to connect or cut off the circulating medium. Gate valves, globe valves, check valves, pressure reducing valves, steam traps and safety valves must be well maintained, and any damage is found. Replace in time.

　　4. Controller, boiler control can enable the boiler to achieve safe, automatic and efficient operation of the boiler during operation, especially in the current environment where the intelligent operation control of the boiler is getting higher and higher, the boiler controller should be well maintained.

　　5. The burner, the burner is the core component of the boiler and the most important equipment in the auxiliary equipment. The quality of the burner is related to whether the boiler thermal efficiency and other parameters meet the standards. Daily inspections should be done to troubleshoot and filter the burner. to clean up.

Gas boiler maintenance precautions

　　1. Power supply. When maintaining the boiler, the power supply must be cut off and the pressure must be relieved.

　　2. Dismantling, the maintenance of the boiler burner should be dismantled, and pay attention to carefully remove carbon deposits and dust.

　　3. Everyday, the boiler safety valve is turned once a day to prevent rust failure.

　　4. When the boiler is shut down, the maintenance method of the boiler should be selected according to the length of the boiler shutdown time. If the boiler is shut down for a short time, if the shutdown does not exceed one month, the wet maintenance method can be adopted, and the dry maintenance method can be adopted for a long shutdown period.

　　The above is to sort out the key components and maintenance precautions for gas boilers for you to refer to and browse for the majority of boiler customers.
