  • Air preheater

    Air preheater. The air preheater uses the hot feed water to preheat the combustion air and obtain a cool water flow in the return. This cold flow can now be used in an additional economiser bundle to further reduce the flue gas temperature. This increases efficiency by 2% points, or flue gas temperatures that are roughly 40K lower.

  • Heating Air with Steam - Engineering ToolBox

    2021-8-27 · Steam is often used to heat air. Steam condensing rate for air heating equipment can be calculated as. m s = q dt c p ρ h e (1). where . m s = rate of condensation, steam consumption (kg/s). q = volumetric air flow rate (m 3 /s). dt = temperature difference in air flow (o C)c p = specific heat of air (kJ/kg o C). ρ = density air (kg/m 3). h e = specific enthalpy of evaporating ...
