Please will someone consider this with me
When a simple water heater burns (a propane/air mixture, for example) is energy lost when the resulting gases expand into the atmosphere? Up the exhaust flue of a domestic boiler for example.
Is this how steam turbine powered ships lose out efficiency wise (nautical miles per tonne of fuel) in comparison with large piston engine powered ships? That the energy resulting from the combustion reaction has it's expansion work utilized?
We are thinking about efficent use of fuels for heat and motive power, simple combustion for water heating clearly appears too crude for the majority of minds here.
We have looked at condensing boilers also but these only operate at the lower temperatures.
thanks in advance
