Principles Underlying the Calculation of Furnace Performance

JSGT 1941 V25 T270-T288

The part played by the combustible gases and products of combustion in heating regenerative and recuperative furnaces is discussed with a view to establishing valid equations for the combustion space required. It is shown that even after allowing for errors in certain assumptions, the equations deduced are applicable to changing conditions in the hearth and consequently can be employed to determine accurately the effect on fuel consumption of varying load, changed hearth wall losses, changed combustion conditions and different regenerator efficiencies.
