One、How to clean gas heating furnace
1. Clean with water
After connecting the cleaning equipment and the gas-fired heating unit, circulate clean water for 10 minutes, then check the system for any leaks. Simultaneously, clean the rust buildup inside the boiler.
2、Removal of anti-corrosion coating and cleaning
Add the surface cleaning agent and controlled-release agent to the circulating water in the cleaning tank according to the specified ratio. Circulate the water for 20 minutes to separate the scale and other components, while also applying a corrosion-resistant treatment to the surfaces of objects that have not been affected by scale. This prevents the cleaning agent from corroding the cleaning components during the cleaning process.
3、Cleaning and removal of dirt and debris
Add the pre-mixed cleaning agent to the circulating water in the cleaning tank according to the specified ratio. Clean and remove scale. Adjust the cleaning and circulation time and the amount of cleaning agent added based on the amount of scale. once all scale has been removed, proceed to the next cleaning step.
4、Passivation Coating Treatment
By applying a passivation coating to the cleaning system using a passivation coating agent, corrosion of pipes and components, as well as the formation of new rust, can be prevented.
5、Water circulation cleaning
Simply flush out all remaining chemical residues within the system. Then, we need to restore the system to its normal operating condition and check if the water supply is functioning properly.
Two. Which areas of a gas-fired wall-mounted boiler require cleaning?
1、Fans
The fan in a gas-fired heating appliance is a crucial component, operating for extended periods during winter. The fan is responsible for exhausting internal exhaust gases and drawing fresh air into the combustion chamber for burning. As a result, dust and sand from the external air can accumulate on the fan blades. Therefore, it is necessary to clean the dust and debris from the blades to reduce the load on the fan and extend its lifespan.
2、Pump
The water pump for the boiler is the component that operates for the longest time, so it is important to maintain its cleanliness and prevent it from seizing.
3、Burner and Main Heat Exchanger
The burner and main heat exchanger of the boiler are also components that are exposed to external dust. If these components are not cleaned regularly, it can affect the normal operation of the gas-fired heating appliance. Therefore, we need to regularly clean the burner and main heat exchanger of the boiler.
