Waste Heat Recovery Boilers: Turn Your Exhaust into Profitable Energy
At IndianBoilers.com, we specialize in high-performance Waste Heat Recovery Boilers (WHRB) designed to capture thermal energy that would otherwise be lost to the atmosphere. By utilizing the hot exhaust gases from DG sets, gas turbines, furnaces, or kilns, our WHRB systems allow your facility to generate process steam or hot water virtually fuel-free.
Our engineering expertise ensures that every unit is custom-sized to match your specific exhaust parameters, providing a rapid return on investment (ROI) while significantly reducing your industrial carbon footprint.
Key Features & Performance
- Zero Additional Fuel Cost: Generates high-quality steam using only the sensible heat from waste gas streams.
- High Heat Recovery Rate: Precision-engineered heat exchangers capable of recovering up to 95% of available waste heat.
- Custom Metallurgy: Options for high-grade Mild Steel (MS) or Stainless Steel (SS) tubes to withstand corrosive flue gases and high temperatures.
- Compact Footprint: Factory-insulated, modular designs that easily integrate into existing exhaust ductwork with minimal modification.
- IBR Compliant & Safe: Built strictly according to Indian Boiler Regulations (IBR) with advanced safety interlocks and pressure controls.

Why Invest in a WHRB System?
- Drastic Fuel Savings: Reduce your dependence on fossil fuels by repurposing heat you already produce. Most units pay for themselves within 12 to 24 months.
- Sustainability Goals: Lowering stack temperatures and reducing fuel combustion directly helps your facility meet global ESG and emission standards.
- Reduced Cooling Loads: Capturing heat from exhaust gases reduces the load on secondary cooling systems, further saving electricity and water.
- Operational Reliability: Our robust construction ensures continuous operation even in high-dust environments typical of Cement and Steel plants.
Core Industry Applications
Our Waste Heat Recovery systems are the preferred choice for energy-intensive sectors:
- Steel & Sponge Iron: Capturing high-temperature kiln exhaust for power or process steam.
- Cement Plants: Recovering heat from pre-heater and clinker cooler exhaust.
- Power Plants: Enhancing DG set or Gas Turbine efficiency through co-generation.
- Chemical & Pharma: Utilizing incinerator or reactor waste heat for jacketed heating.
- Glass & Aluminum: Capturing intense furnace heat for facility-wide utilities.
