Fault Treatment Of Condensing Boiler Burner
Fault Treatment Of Condensing Boiler Burner
Scaling, corrosion, burner blockage, impurities, and other problems with the boiler are the main reasons for the normal operation of the condensing boiler and burner. The hardness components in the water, after continuous evaporation and concentration at high temperature and high pressure, will eventually produce scale or rust in the boiler. This is the main reason for the corrosion of the boiler scale and water wall. This will reduce the heat absorption of the boiler water-cooled fireplace, increase the outlet temperature of the boiler furnace, increase the boiler loss, and reduce the heat transfer effect. It may also lead to an increase in the wall temperature of the water-cooled wall, which may lead to a tube explosion of the water-cooled wall, which will directly affect the safe operation of the boiler.
The burners used in condensing boilers generally use liquid and gas injection as the combustion mode, so that the fuel injection is smooth and ignition becomes a necessary condition. Four fault points are summarized: the ignition rod does not ignite, the ignition rod has sparks but does not ignite, the fuel injection intensity is increased when it goes out or flickers unsteadily, and the burner noise is large. The reasons for these problems are different.
The reasons why the ignition rod of the combustion engine of the condensing boiler does not ignite are: the crevice is blocked, the moisture is affected, the electric leakage, the distance between the ignition rods is inconsistent, the skin is damaged, the short circuit, etc. these reasons are due to improper operation and no regular maintenance. This fault is easy to deal with. As long as the natural gas boiler burner is cleaned, replaced, replaced, and the distance between the ignition rods is adjusted, it can be solved.
There are also sparks on the ignition rod of the combustion engine of the condensing boiler, which means that it cannot ignite. The main reasons are blockage, poor ventilation, too small setting angle of the damper, the improper distance between the tip of the ignition rod and the leading edge of the oil nozzle, blockage of the solenoid valve of the first oil gun by sundries, blockage of the filter screen of the oil pump itself, and a large amount of water in the oil. This solution is relatively troublesome. The burner of the condensing boiler can be cleaned, replaced, debugged, and tested.
