Calculate the total flue gas flow and heat of the waste heat boiler.
Thread Content
For a carbon monoxide burner + waste heat boiler: the flue gas volume coming from the regenerator is 20,000 NM3/h; the amount of air required for combustion in the carbon monoxide burner is 2,000 NM3/h, and the amount of gas used is 100 NM3/h. Calculate the total flue gas flow rate and the associated heat quantity.
Generally, the flue gas volume is estimated as air volume * 1.1!
Hello, teacher. Could you please give me the calculation process?
*1.1 is an empirical value; there is no calculation formula
Why are the air supply and gas flow rates for your CO incinerator so low? Here, the air supply is 24,000 Nm3/h, while the gas flow rate is 3,000 Nm3/h
For a detailed calculation, it is necessary to know the analysis of the flue gas composition entering the incinerator; based on this composition, the theoretical oxygen consumption and the resulting products are calculated. The gas composition is used to determine the oxygen consumption associated with that gas and its composition after combustion. It is a step-by-step calculation process, and finally, the total amount of products used is divided by the total input to obtain the proportions of various components – which makes the process somewhat complicated.
