APPENDIX 1 MEASURING BOILER EFFICIENCY

The losses caused by the sensible heat of flue gases can be calculated as: m& i φ L 3 = m& fuel ⋅ ∑ ⋅ hi (11) i m& fuel where m& fuel is the fuel mass flow [kg/s], m& i the mass flow of a flue gas component, and hi the specific enthalpy of a flue gas component (e.g. CO2) [kJ/kg].

Efficiency of biomass boilers is generally above 80%, max. can reach 88.3%, 15% higher than the average efficiency of coal-fired boilers. Five advantages: Biomass boilers require new green energy, compared to other boilers, biomass boiler has the following four advantages: 1. A multi-purpose boiler: can be used for cooking, water heating and

and water entering the boiler is assumed at 25oC. The flue gas leaves the boiler at 300oC (all the water formed will be vapour). In addition, a substantial amount of heat is also lost through the boiler wall and other uncounted sources. Calculate the flue gas composition (both dry and wet basis) leaving a boiler.

Flue Gas Condensers Introduction. Flue gases from large boilers are typically 450 650°F. Stack Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with boiler operation.
