Mixing coking gas with natural gas for use
Thread Content
For a newly built facility, natural gas is to be used as fuel for the heating furnace in the initial stage; once there is a sufficient supply of coking gas available, it will be used alongside natural gas. Is this design feasible? What are the issues that need to be taken into consideration?
It is completely possible; two things need to be taken into account: 1. the fuel media must not mix with each other due to differences in pressure, and 2. how to adjust the proportions to meet the heat requirements. It is recommended to add a fuel gas buffer tank, which would be better
1. Purification of coke oven gas, desulfurization, dust removal, tar removal; pipeline design with drainage function; buffer tank designed before the heating furnace； 2. Natural gas is adjusted according to the calorific value of coke oven gas, with the calorific value stabilized at 1700 kcal and the pressure around 15 KP ； 3. The permanent light system of the heating furnace is equipped with an independent gas supply ； 4. Distance between the permanent light of the heating furnace and the main burner ； 5. Requirements for air preheating temperature in the heating furnace ； 7. Air ratio in the heating furnace. Any of the above factors can affect the quality of combustion, whether the environmental emissions tests pass, and whether the burner goes out
