Waste Gas Fired Boilers

Waste Gas Fired Boilers

Engineered to burn industrial waste gases / tail gases to generate steam for process or power

Submit your enquiry

TBWES' waste gas fired boilers are designed for efficient energy recovery from process gases in various industries. Typical applications include carbon black plants and ferro alloy plants, where carbon monoxide (CO) gas is utilised for steam generation, and caustic soda plants, which use hydrogen (H₂) gas as a fuel source. 

By capturing and utilising waste gases, these systems significantly lower fuel costs, enhance thermal efficiency, and reduce greenhouse gas emissions. Our WHRBs play a vital role in advancing circular economy principles and enabling sustainable industrial operations, turning waste into a valuable energy source.

WHRB in Refinery & Petrochemical Plant

WHRB in Refinery & Petrochemical Plant

Efficient heat recovery system designed to utilise flue gas energy from FCCU operations in refineries

Submit your enquiry

TBWES offers waste heat recovery boiler (WHRB) downstream of Fluid Catalytic Cracking Unit (FCCU).

These WHRBs capture high-temperature flue gases to generate steam, enhancing overall refinery energy efficiency. Designed to handle catalytic dust, sulphur dew point corrosion, and thermal stresses, the WHRBs improve process integration, reduces fuel consumption, and supports sustainable refinery operations through effective heat utilisation and emissions control.
