In steel industry, where a large amount of Blast Furnace Gas and Coke Oven Gas are produced and consumed, the calorie control of these gases are very important from the view point of the combustion control and quality control of steel products.
The coke rate of Blast Furnace has decreased with improvement of the furnace operation and the heating value of BFG has decreased to less than 900kcal/Nm3. Consequently, the conventional calorimeter has become useless for its original purpose. Moreover, the conventional one is not adequate for use in the calorie control because of its time lags, maintenance difficulties, poor reliabilities and difficulties in connection with an instrument.
Described in this report are the development of a new calorie sensor using a thermocouple and the calorie control of BFG with this sensor.
This sensor can be used to measure and to control highcalorie gases such as city-gas and other chemical process gases.
