Blast furnace temperature control
Thread Content
If the average temperature in the coke oven is too low or too high, should adjustments be made by increasing or decreasing the gas flow rate in the main pipeline, or by increasing or decreasing the pressure in the main pipeline? By how much can the temperature change for each certain change in flow rate or pressure?
The temperature control of coke ovens is usually achieved by adjusting the main gas flow rate. If the temperature is low, it will increase the gas flow rate ； If the temperature is too high, the gas flow will be reduced. As for the pressure on the controller, generally speaking, it also affects the supply volume of gas, which in turn influences the furnace temperature; it is also an important parameter for regulating the gas flow rate. However, there is no specific answer to the question of how much the temperature can change for each certain change in flow rate or pressure. Because changes in furnace temperature are influenced by many factors, such as combustion efficiency, the insulation of the furnace, and coal quality. The specific conditions of each coke oven are unique; therefore, this value must be determined through a series of tests and experience in actual operation. Generally, when designing coke ovens, manufacturers provide a set of operating parameters for reference, which are adjusted according to the actual operating conditions. .
