About Waste Heat Recovery Boiler
Gyantosh's Waste Heat Recovery Boilers (WHRB / HRSG) capture the hot exhaust gases from upstream processes — DG-set exhaust, furnaces, kilns, incinerators, and other high-temperature streams — and convert that otherwise-wasted energy into useful steam. This dramatically cuts fuel cost and emissions, because the steam is generated from heat you have already paid for.
Because a WHRB uses no primary fuel of its own, it is one of the most cost-effective and sustainable ways to raise plant energy efficiency. Modular, compact designs are engineered around the available waste-heat quantity, gas temperature, and required steam parameters — suiting both new plants and modernization/retrofit of existing installations.
Every waste heat recovery boiler is designed and manufactured in compliance with IBR 1950 and IS 2825 using certified boiler-quality pressure parts, with heat transfer surfaces and gas-path design tailored to the source gas characteristics. An integral economiser further improves heat recovery.
Steam capacity and pressure are set by the available waste heat and process requirement. GyanTosh WHRBs serve fertilizer, steel, paper, cement, glass, chemical, refinery, and power plants seeking to slash energy cost and carbon footprint. Backed by over two decades of boiler engineering experience.

Waste Heat Recovery Boiler Specification
Waste Heat Source
Heat Recovery Configuration
Heat recovery steam generator surfaces are arranged in the exhaust gas path to extract maximum energy from the waste-gas stream into feed water and steam.
Tube arrangement, gas velocity, and materials are matched to the source gas temperature, dust loading, and corrosiveness for reliable long-term operation.
An economiser preheats feed water using residual gas heat, pushing overall heat recovery and efficiency higher.
A modular design minimises footprint and back-pressure on the parent process, easing retrofit into existing plants.

Advantages of a Waste Heat Recovery Boiler
A WHRB generates steam from heat that would otherwise be lost, so the steam is effectively free — delivering major operating-cost savings.
Recovering waste heat reduces the fuel burned elsewhere, cutting the plant's overall emissions and carbon footprint.
Fuel and emission savings typically give waste heat recovery boilers an attractive, short payback period.
Modular, compact design allows integration into existing plants with minimal disruption and low back-pressure on the parent process.
Each WHRB is sized precisely to the available waste heat, gas characteristics, and steam requirement for optimum recovery.
Improving energy efficiency through heat recovery supports corporate sustainability and energy-conservation goals.
