Thermal calculation for flue gas cooling
Thread Content
I would like to ask fellow sailors: when performing thermal calculations for the cooling of flue gas (for example, from 93 degrees Celsius to 50 degrees Celsius), regarding the enthalpy of the mixed flue gas, which specific enthalpy value should be referred to according to the \"Handbook of Property Data for Chemicals and Chemical Engineering Materials\"? Is it the specific enthalpy of an ideal gas, or is it the specific enthalpy at certain temperatures that is interpolated, or is it the specific enthalpy at a certain pressure that is interpolated? It feels a lot worse, thanks for letting me know
I know it is checked based on the components of the flue gas, but when looking up specific values, is it based on specific enthalpy? Is it based on an ideal gas, or on a temperature table, or on a pressure table?
You can calculate it by yourself using the method outlined in the industrial boiler design table; it’s very simple
OP, please take a screenshot to show what information you have currently found or calculated
The specialized calculation manual provides the specific enthalpy of flue gas at various temperatures. For greater detail, it is possible to analyze the composition of the flue gas, calculate the specific enthalpy of each component, and then apply weighting.
