Guide: The oil-gas boiler generates a large amount of reducing atmosphere between the grate air and the secondary air, under the strong disturbance of the high temperature flue gas in the furnace and the fire of the grate air, and releases the heat that reaches the load. The following editor tells you the conditions for the combustion of oil and gas boilers are as follows:
Is there any way to increase the combustion efficiency of oil and gas boilers?
The oil-gas boiler generates a large amount of reducing atmosphere between the grate air and the secondary air, under the strong disturbance of the high temperature flue gas in the furnace and the fire of the grate air, and releases the heat that reaches the load. The following editor tells you the conditions for the combustion of oil and gas boilers are as follows:
1. The grate holes are unobstructed, the inclination angle is reasonable, and the stopping interval, vibration frequency and vibration time are appropriate.
2. The first wind penetrates the fuel, and the bottom fire wind is abundant and slightly boiling.
3. The secondary air has a reasonable inclination angle and suppresses the upper string of flames.
4. The suitable oxygen content is 3%-6%. The straw fuel has low carbon content, large volatile content, large ash content, large fuel void ratio and long burnout time, which requires oxygen-enriched combustion.
5. Use ignition air according to the dryness of the fuel, try to increase the preheating temperature of the fuel, and form a fire on the grate.
6. Keep the fuel moisture below 20% and reduce the ignition temperature.
7. Keep the fuel ash content below 20% to increase the burnout degree.
8. The fuel distribution on the grate is high in the middle and low on both sides, and the thickness is suitable.
9. The fuel should be as fine as possible and the particle size should be suitable to maintain a good bonding surface with oxygen.
10. Keep continuous feeding to avoid segmentation.
11. The ratio of primary and secondary air is 3:7 or 4:6. The air rate is selected according to different materials to make the air rate suitable for fuel combustion.
12. The secondary air enters in time, stirs the gas in the furnace to mix it, causes the flue gas in the furnace to produce a vortex, increases the stroke of the suspended fly ash and fly ash combustibles in the furnace, and further reduces the fly ash and fly ash combustibles .
