Some Deductions from the Furnace Performance Formula
JSGT 1946 V30 T295-T302
It is deduced from the furnace performance formula that, for glass tank furnaces having the same values of Q the coal to glass ratio decreases progressively with increasing furnace size, while the thermal efficiency increases with size. It is also shown that the standard performance formula can be used to deduce the relationship between glass output and temperature when the heat input to the furnace is constant, and also the relation between the calorific value of the fuel and temperature when a constant weight of fuel is used. A form of the performance formula is given which enables Q to be calculated when the values of the coal to glass ratio and sq. ft./ton day are known.
