Calculating exhaust gas CFM. - Engine & fuel

Nov 30, 2004· SBBBlue gives the best explanation, but I have found over many years of flow-bench testing exhaust systems, then measuring on-car (or -truck) exhaust backpressures, that a very good simple approximation of the exhaust gas flowrate is to use the engine volume x rpm x .5 (for a four-stroke) then correct for gas temperature.

Condensing boiler - Wikipedia

Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.
