Lime kiln with gas fuel ignition

Lime kiln with gas fuel ignition procedures are as follows:
1. Start the kiln tail fan, ventilation time of not less than 10 minutes. To ensure that the kiln pressure to maintain the -200 ~ -300Pa.
2. Before the lime kiln ignition, use gas to clean the gas pipeline and gas collection pipe. Remove the burner valve when discharging. In the gas pipeline to the atmosphere during the sewage, the radius of 40 meters should be prohibited within the usage of open flame and welding work, unrelated to prohibit entry.
3. Before the burner is about to ignite, you must check whether there is sufficient pressure in the gas pipeline before the kiln and whether the kiln is in a negative pressure state.
4. Start the combustion air blower, to determine the minimum amount of air into the burner.
5. The igniter or torch to the mouth of the mouth, convinced that there is pumping force, and gradually open the gas pipeline on the valve, the gas sent to the flame smoothly. If the gas through the burner into the kiln is not lit, or lit and then extinguished, must stop for gas, the kiln ventilation, troubleshooting and then re-ignition.
6. Burner ignition, adjust the burner so that the gas and air flow is about equal to the rated flow of 80%, then pay attention to the burner at or without negative pressure, if necessary, adjust the ventilation so that the pressure at the burner to -20 ~ -30Pa.
7. Always adjust the chemical composition and temperature of the gas in the kiln for at least 30 minutes during the ignition adjustment. According to the composition of the gas to determine the full degree of gas combustion and air consumption coefficient. If the content of carbon monoxide and hydrogen is high, it is proved that the air supplied to the burner is insufficient, and the burner should be adjusted to reduce the amount of combustion gas or increase the amount of combustion air. While the oxygen content of the kiln gas is high, the amount of air in the kiln should be reduced.
8. After the kiln pressure and gas components are normal, the burner can burn at normal flow rate.
Lime kiln with gas fuel ignition has advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.
