A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).
Heat Recovery Steam Generators (HRSG) for engine cogeneration (CHP) and other industrial waste heat systems involves much consideration. Important areas of focus are controlling/bypassing the exhaust heat, optimizing overall system performance, maintaining required operating pressures, boiler size, weight and installation. HRSG are designed to address these concerns and more with standard design features not found in conventional waste heat boilers. HRSG can also adapt to any retrofit application or new installation.
Martin Energy Group’s use of Heat Recovery Steam Generators (HRSG) in cogeneration systems are specifically designed for gas and diesel engine, gas turbine and micro turbine generator retrofit applications. We provide a comprehensive analysis and quotation to fit your exact. Our equipment can be adapted and assembled to fit any application or complete installation.

BTU is transferred from the exhaust stream to heat sinks such as water, glycol, therminol fluids, or steam production. Suitable fuel types for combustion sources include natural gas, propane, digester gas, diesel fuel and light to heavy fuel oils.
- Large or irregular exhaust connections
- High or varying exhaust temperatures
- Particular pinch point requirements
- Exhaust or liquid control
- Special heat sink requirements
- Special heat transfer metallurgy requirements
- Specific maintenance concerns
- Optional equipment requirements
- Installation space and weight concerns
- Package system requirements
- Tremendous fuel savings typically pay for equipment and installation within 1 to 3 years of average use.
- Pollution reduction due to lowered annual fuel usage.
- Lower exhaust temperatures and significantly reduced sound output levels (final sound attenuation is typically 15 – 25 dBA).
