How does the variation in gas calorific value affect the efficiency of heating furnaces?
Thread Content
How can the efficiency of a heating furnace be determined through calculations, based on changes in the calorific value of gas? It would be best to have proper steps and methods for solving this issue, to facilitate the development of the software; I hope that those with expertise can share their insights.
What software are you using? Accurate calculations of the relationships between various indicators are necessary; generally, the higher the calorific value of the gas, the smaller the losses, and thus the heating efficiency of the entire furnace will be higher.
I once tried to use calculations to show the relationship between changes in the calorific value of gas and the efficiency of heating furnaces; thinking about it now, I realize it’s quite difficult to achieve
Generally, the higher the calorific value of the gas, the higher the flame temperature, and the greater the heat absorbed by the radiation chamber; as a result, the temperature of the flue gas exiting the radiation chamber decreases, leading to an increase in thermal efficiency. This can be simulated when using the PFR program.
