Abstract: Develops a mathematical model for flame furnaces. Then the influence of changing operation parameters on production indexes is investigated with the structural parameters of flame furnaces kept constant to obtain and compare the Q-P equations and b-P equations of both continuous heating regenerative furnace and heat-exchange furnace. The results show that during normal production the thermal load of continuous heating regenerative furnace increases linearly with its productivity but the specific energy consumption reduces very slowly and approximately linearly. At the same time, the change in temperature of exhaust gas and thermal efficiency almost keep constant and linear. As to the heat-exchange furnace, the thermal load of furnace and temperature of exhaust gas increase gradually, and the specific energy consumption decreases first then increases with the thermal efficiency changing vice versa. Comparing the two types of furnaces with each other, the regenerative one shows a much wider operation range and is more suitable for the production with widely changed output.
