3 Thermal balance test and calculation basis

3.1 reference temperature Using the average temperature of the environment, that is, the average ambient temperature of the heat treatment furnace within 1 m from the furnace wall. 3.2 fuel calorific value The low (bit) calorific value of the wet gas is used for the gaseous fuel, and the low (bit) calorific value is received for the liquid fuel. 3.3 Thermal balance test range According to the test requirements, generally do the furnace heat balance, if the waste heat recovery device is the whole furnace (including waste heat recovery device). 3.4 Heat balance test time The test time for the intermittent heat treatment furnace is a heating cycle, i.e., from the start of heating to the complete stop of the supply of fuel. On the continuous Type heat treatment furnace should be in continuous conditions for continuous testing, the general should be tested more than 2 times, each time not less than 2h. 3.5 Heat balance calculation unit The amount of heat consumed per ton of furnace material is calculated as kJ/t.
