Boilers
Efficiency, losses, blowdown, cold-end corrosion and other boiler-side calculations.
Boiler Efficiency, Gaseous Fuels (ASME PTC 4)
Indirect-method efficiency of a gas-fired boiler from the fuel gas analysis, excess air, stack and air temperatures: PTC 4 losses and credits on GCV and NCV.
Boiler Efficiency, Solid and Liquid Fuels (ASME PTC 4)
Indirect-method efficiency of a coal, biomass or oil fired boiler: every PTC 4 loss and credit from the fuel analysis, excess air, stack and air temperatures.
Stack Loss: Dry Gas and Moisture Losses
The four stack losses of a boiler (dry gas, water from hydrogen, fuel moisture, air moisture) per kg fuel and as a fraction of GCV, from measured gas quantities and temperatures.
Sulphuric Acid Dew Point of Flue Gas
Acid dew point by Verhoff–Banchero from flue gas water vapour and SO₃, with SO₃ entered directly or estimated from fuel sulphur.
