The hot water boiler may accumulate a large amount of smoke after using it for a period of time. At this time, everyone needs to clean it up in time, so as to avoid clogging and cause operational failure. So how to deal with it effectively when there is too much soot in the hot water boiler? Here is the specific introduction:
The electric hot water boiler has been cleaning the tail flue without stopping for a long time, and a certain amount of soot or carbon black has accumulated. Solution: When the temperature in the flue fluctuates below 50 ° C, enter the flue to check the heating surface on the tail. At the same time, the smoke in the flue should be completely removed. If it is not burned, restart the ignition; if it is burnt, replace and repair the burned parts; if the negative pressure in the combustion chamber is too large, it will be brought into the tail of the electric hot water boiler before the gas burns out.
Solution: When the exhaust temperature is close to the temperature of the injected steam, or less than 150 ℃ and stable for more than 1h, the inspection hole can be opened for inspection. After the ignition source is checked, the fan ventilation can be started.
The air gun valve was not closed when the furnace was shut down or the electric hot water boiler was extinguished.
Solution: strengthen the water inlet and drain of the electric hot water boiler, or open the valve of the economizer recirculation pipe to protect the economizer from being burnt;
During the process of starting and stopping the furnace, the temperature of the furnace was low, and the fuel was not burned in the furnace.
Solution: Immediately put in steam fire extinguishing equipment, carbon dioxide or other fire extinguishing equipment to extinguish the fire; improper combustion adjustment, insufficient air distribution or unreasonable air distribution. Solution: Close the flue, air duct baffle and door holes everywhere.
