What is a Waste Heat Recovery Boiler?

A Waste Heat Recovery Boiler (WHRB) is a specialized industrial boiler that utilizes heat from flue gases generated by equipment such as furnaces, kilns, gas turbines, diesel generators, and incinerators.

Instead of releasing this heat into the environment, the WHRB captures it and produces steam or hot water without additional fuel firing, making it an eco-friendly and cost-effective energy solution.

How Waste Heat Recovery Boilers Work

Waste Heat Recovery Boilers are installed directly in the exhaust gas stream of industrial processes. Hot flue gases from furnaces, kilns, turbines, and generators are directed through the boiler system.

These hot gases pass over specially engineered heat exchange surfaces, where their thermal energy is transferred to water circulating inside the boiler tubes. This process generates steam or hot water without any additional fuel consumption.

The recovered energy can then be reused for power generation, process heating, or plant utilities—significantly reducing dependence on conventional fuels and improving overall plant efficiency.

Waste Heat Recovery Boilers – FAQs

What is a Waste Heat Recovery Boiler (WHRB)? +
A Waste Heat Recovery Boiler is an energy-efficient boiler that recovers waste heat from exhaust gases of industrial processes and converts it into useful steam or hot water without using additional fuel.
How does a Waste Heat Recovery Boiler work? +
WHRBs capture high-temperature exhaust gases from equipment like furnaces, kilns, gas turbines, or DG sets. The heat is transferred to water through heat exchange tubes, producing steam or hot water for reuse in the plant
What industries use Waste Heat Recovery Boilers? +
Waste Heat Recovery Boilers are commonly used in cement, steel, power plants, chemical and petrochemical industries, refineries, glass manufacturing, paper & pulp, textile, and food processing industries.
What are the main benefits of installing a WHRB? +
Key benefits include reduced fuel consumption, lower energy costs, improved plant efficiency, reduced carbon emissions, faster ROI, and support for sustainable manufacturing.
Does a Waste Heat Recovery Boiler require additional fuel? +
No. Unfired WHRBs operate entirely on waste heat. However, supplementary-fired WHRBs can use additional fuel when higher steam output is required.
What types of Waste Heat Recovery Boilers are available? +
Common types include unfired WHRBs, supplementary-fired WHRBs, water tube WHRBs, smoke tube WHRBs, and horizontal or vertical design boilers.
Can a WHRB be customized for my industrial process? +
Yes. Waste Heat Recovery Boilers are custom-designed based on exhaust gas temperature, flow rate, pressure requirements, space availability, and industry application.
Is a Waste Heat Recovery Boiler environmentally friendly? +
Yes. WHRBs reduce fuel usage and greenhouse gas emissions by utilizing waste heat, making them an eco-friendly and sustainable energy solution.
What is the maintenance requirement for WHRBs? +
WHRBs require minimal maintenance when properly designed and operated. Regular inspection, cleaning of heat transfer surfaces, and routine checks ensure long service life and efficient performance.
