Thermocouple For Coke Oven

Hot Rolling Mill and brief process of Hot Rolling Mill

Coke oven is a process to convert natural coal into coke for use in Blast Furnaces. Precise temperature control is require in the Coke Oven in order to ensure complete removal of volatile matter, ash, moisture & to improve the crushing strength of coke Thermocouples protection tube is of C799/ KER710 grade which can withstand for higher temp up to 1500° C

Types of Coke Plant

There are two types of coke ovens (Non-Recovery & Heat Recovery Coke Oven.)

In Non-recovery we get the final product as Coke & in Recovery oven we get the Coke as main product with CO gas and other various gases, which are used further, as by products

Need of Temperature measurement in Coke Oven

Coke is indispensable raw material in the production of iron making, and its quality affect the quality of iron directly.

The important control in coke oven is the efficient utilization of heat i.e. temperature control. If the oven temperature is too low, the heat penetration rate is slow and hence it adversely affects overall carbonization time and coke quality

Our Model

PTRH-PT thermocouples are installed in bottom and top zone of the ovens for temperature monitoring
