Gas-fired hot water boilers have fast heating and high thermal efficiency, and are widely used in heating and production. So what are the maintenance methods for gas-fired hot water boilers? How to better ensure the safety of gas hot water boilers during use?

Maintenance method of gas hot water boiler

　　The maintenance of the gas-fired hot water boiler should be carried out according to the length of the shutdown time, and appropriate methods should be adopted:

　　1. Pressure maintenance, the pressure maintenance method for hot water boilers is for the situation of shutdown and short-term maintenance. The specific method is to drain the boiler water, clean the dirt in the boiler, rinse and add boiler water, and conduct steady heating to ensure the water temperature. Hold at 10 degrees Celsius.

　　2. Wet maintenance, if the hot water boiler has been shut down for more than a month, drain the boiler water, then clean up the dirt, then close all the inlet holes and valves, and finally put the protective solution into the boiler, and do a good job during the shutdown period. Fire oven.

　　3. Dry maintenance. If the production and other factors affect the boiler, the boiler needs to be shut down for a long time. At this time, after the water is drained and the dirt is cleaned, an appropriate amount of desiccant is put into the boiler to absorb moisture. It should be noted that the desiccant cannot be heated with the boiler. Direct contact with the surface of the boiler, and check whether the desiccant causes corrosion problems to the boiler in the later stage.

Safe operation of gas hot water boiler

　　1. Pay attention to starting and stopping. Before starting the hot water boiler, all preparations should be done, such as determining the normal state of all aspects of the boiler, such as burner, pressure, various instruments, and whether the gas supply and water supply are normal, whether the valve is open, etc. . Shutdown should follow the operation sequence and requirements, such as closing the gas shut-off valve after the boiler is turned off and shut down.

　　2. Operation attention, monitoring and inspection work should be done during the operation of the gas boiler, water leakage and other problems should be eliminated in time after abnormal noise is found, and the furnace should be shut down for maintenance and inspection if necessary.

　　The above is an introduction to the maintenance methods of gas-fired hot water boilers for you, as well as the operation and attention of the safe use of gas-fired hot water boilers, for the reference of the majority of boiler customers.
