COKE OVEN PLANT

Waste Heat Boilers for Coke Oven Batteries

The coke making process involves carbonization of coal to high temperatures (1100°C) in an oxygen deficient atmosphere in order to concentrate the carbon. Charged coal is heated in oven and volatile matter is released from coal. This burning of volatile matter provides the heat required for the coke making process.

Heat generated due to combustion is partially utilized in making Coke and balance heat goes with waste flue gas and recovered in WHRB generating steam at pressure which drive turbogenerator to generates power.

There are two processes of making commercial coke in steel industry

– By-product Coke making
– Non-Recovery / Heat Recovery Coke making

TSPL provides efficient WHB at exhaust of COB for both coke making process for Steel plants & independent Coke Making plants.

TSPL provides Waste Heat Boilers which are best suited for In-line and Offset configuration to Coke Oven Batteries.

WASTE HEAT RECOVERY BOILERS

For Non Recovery Type Coke Oven Batteries

In Non-recovery coke plants, the carbonization process takes place in large oven chambers where Primary air for combustion is introduced into the oven chamber. Combusted gases / Waste Gas  exit through common tunnel is fed into a waste heat recovery boiler to convert waste heat into steam for power generation.

Since by-products are not recovered & Waste heat is converted to Steam, the process is called Non-Recovery / Heat Recovery Coke making.

Inline Configuration - Coke Oven Battery & WHBs

In the production of Low Ash Metallurgical Coke (LAMC), large quantities of heat is carried away by flue gases and the hot coke itself. We have successfully operating WH Boilers, Custom Built to suit the plant layouts & location of gas tapping

Offset Configuration - Coke Oven Battery & WHBs

In the production of Low Ash Metallurgical Coke (LAMC), large quantities of heat is carried away by flue gases and the hot coke itself. We have successfully operating WH Boilers, Custom Built to suit the plant layouts & location of gas tapping

WASTE HEAT RECOVERY BOILERS

For Recovery Type Coke Oven Batteries / Coke Dry Quenching

In Dry Coke Quenching process, Red-hot coke at about 1,100°C is charged into the coke cooling tower, and inert gas normally Nitrogen is blown into the tower from the bottom.

Heat exchange takes place with the circulating inert gas. After the gas is heated to a high temperature at around 800°C, it is introduced to waste heat recovery boiler to generate steam.
