Any fuel heater may produce carbon buildup, and the Chinese diesel heater is no exception. After carbon buildup are formed in the combustion chamber of the chinese diesel heater, if the carbon buildup are not cleaned up in time, a large amount of accumulation will result in failure of the heater to ignite and smoke from the heater.
The causes of carbon deposits in the chinese diesel heater are usually:
Insufficient fuel combustion: When the pump fuel volume is greater than the demand for a long time, the fuel combustion in the combustion chamber is not fully burned and it is easy to form carbon deposits. At this time, the heater can be dry burned for 3 to 5 times without pumping fuel, if the situation is not available Relieve and clean up carbon deposits.
Airflow is restricted: the total length of the intake pipe + exhaust pipe is too long. It is generally recommended that the total length of the two combined is less than 5 meters. If a muffler is installed, the total length should be shorter.
Low oil quality: Many drivers use oil from small gas stations. These oils are low-refined and blended oils in professional terms, mixed with a lot of biodiesel smelted from waste oil. These low-quality oils contain more impurities. The moisture is large, there are more particulates and other substances after combustion, and long-term accumulation will cause carbon deposits in the combustion chamber
How to clean up the carbon buildup
Disassemble the parking heater, first use a flat-blade screwdriver to clean the carbon deposits on the burner, the combustion tube and the inner wall of the furnace, then clean the burner with a cleaning agent, and finally blow the burner with an air gun. If it is not ventilated, replace the burner ; Be careful not to damage any parts in the process of dismantling the parking heater and cleaning up the carbon deposits to avoid damage to the machine.
