Waste Gas Fired Boilers: Turn Industrial Exhaust into Free Energy
At IndianBoilers.com, we specialize in high-efficiency Waste Gas Fired Boilers (Heat Recovery Steam Generators) designed to capture thermal energy from exhaust gases that would otherwise be lost to the atmosphere. Whether it is exhaust from Diesel Generator (DG) sets, gas turbines, or industrial furnaces, our systems convert “waste” into a valuable utility, providing your facility with steam or hot water at virtually zero fuel cost.
Key Features & Performance
- Maximum Heat Recovery: Precision-engineered heat exchangers designed to recover up to 95% of available sensible heat from exhaust streams.
- Zero Fuel Consumption: Operates entirely on the thermal energy of waste gases; no auxiliary burners are required for standard operation.
- Low Back-Pressure Design: Custom-sized smoke tubes ensure minimal resistance to the upstream equipment (engines/turbines), maintaining their operational efficiency.
- Multi-Exhaust Connectivity: Our modular designs allow multiple exhaust sources to be connected to a single boiler unit for centralized steam generation.
- Compact & Packaged: Factory-insulated and skid-mounted designs for rapid installation and a smaller footprint in your utility area.

Why Invest in Waste Gas Boilers?
- Rapid ROI: Since the fuel (waste gas) is free, most industrial units achieve a complete Return on Investment within 12 to 18 months through fuel savings.
- Carbon Footprint Reduction: By replacing fossil fuel-fired boilers with waste heat recovery, you significantly lower CO2 emissions and meet green manufacturing mandates.
- Durability: Built with high-grade, corrosion-resistant boiler tubes to withstand the chemical composition of various industrial exhaust gases.
- Ease of Maintenance: Features large inspection doors and a simplified tube layout for quick descaling and maintenance.
Core Industry Applications
Our waste gas fired systems are essential for industries looking to optimize their energy balance:
- Power Plants: Utilizing DG set or Gas Turbine exhaust for auxiliary steam.
