Cleaver-Brooks

Heat Recovery Steam Generators

Cleaver-Brooks HRSG Solutions meet today's CHP application needs.

Cleaver-Brooks is the leading provider of energy recovery solutions and the only totally integrated, single-source supplier in the world, from gas turbine or reciprocating engine exhaust to stack outlet. Whether you need a packaged Heat Recovery Steam Generator (HRSG) or a field-erected, modular HRSG, our systems achieve energy efficiency, emissions reduction and decarbonization.

Supporting your sustainability goals, our HRSG solutions can:

  1. Increase onsite power generation efficiency by >80%.
  2. Reduce fuel usage up to 7.0 MMBTU/hr in conventional boilers.
  3. Eliminate 2,870 tons of CO2 emissions annually for every MWe of gas turbine generation.

CHP & Cleaver-Brooks

Combined Heat and Power, or CHP, can increase overall plant efficiency by 30 to 40 percent, adding onsite power generation and heat recovery required for downstream heating or process needs. The HRSG is an integral component to any CHP system. When coupled with an SCR, an HRSG can significantly reduce greenhouse gas emissions, while also providing plant reliability and increased efficiency.

The Cleaver-Brooks HRSG line utilizes the exhaust from gas turbines or reciprocating engines to achieve efficiencies of more than 80 percent, compared to 56 percent for traditional technologies such as conventional electricity generation and an onsite boiler.

Our project teams ensure that the HRSG system is designed to your specifications, and our trained craftsmen produce boilers that are guaranteed to meet your exact standards. With state-of-the-art technology and expertise earned during 100 years in the industry, Cleaver-Brooks delivers reliability, sustainability and overall plant efficiency.
