What is the operating principle of dual-purpose oil and gas burner equipment?
After successful ignition of the boiler and normal operation, load adjustment can be carried out. At this time, it is necessary to regularly observe the combustion situation inside the furnace. If there is poor atomization of oil and gas, flame jumping, flame hitting the furnace liner, and high or low exhaust temperature, timely adjustments should be made to the oil pressure, oil temperature, steam volume, air volume, air pressure, and steam pressure to ensure safe and economical operation of the boiler. The size of oil pressure and air pressure is related to the load of the boiler. The adjustment of oil pressure is achieved by adjusting the pressure of the burner or the amount of return oil, and the adjustment of air pressure is achieved through the opening of the valve.
When adjusting the load, adjust the oil and air pressure, and at the same time, adjust the air volume synchronously to ensure a reasonable match between oil and air volume, in order to achieve the goal of economic operation of the boiler. 1. The method for judging the combustion situation of fuel and gas boilers: (1) Judging the quality of combustion from flame color and smoke exhaust color; (2) Judging the quality of combustion from flame length; (3) Judging the quality of combustion from CO2 content and excess air coefficient in smoke
2. The combustion adjustment method for oil fired boilers: During normal combustion, the flame in the furnace is stable, white orange in color, and generally has a rumbling sound. If the flame jumps or there is an abnormal sound, the oil and air volume should be adjusted in a timely manner. If there is no improvement after adjustment, the engine should be turned off to identify the cause, and measures should be taken before re ignition.
