The dry flue gas loss depends on the mass of flue gas and on

  • A.the pressure at which the boiler operates
  • B.its temperature rise above ambient
  • C.the moisture content of the fuel
  • D.the hydrogen content of the fuel

Answer: B

The loss is the mass multiplied by the specific heat and by the rise above ambient, so both the quantity of gas, which follows from the excess air, and its exit temperature enter. Hydrogen and fuel moisture are separate loss heads.
