Modular HRSG

Heat Recovery Steam Generator

  • Steam flow 10,000 to 1,000,000 lb/hr
  • Steam Temperature to 1050°F
  • Up to 2300 psig
  • Available to less than 2 ppm NOx

Cleaver-Brooks modular, natural circulation HRSGs are designed specifically for larger gas flows. Single or multiple pressure levels can be accommodate to optimize system/cycle efficiency.

Cleaver-Brooks' energy recovery international Modular HRSGs are designed to accommodate exhaust flows greater than 400,000 lb/hr. The Modular HRSG is designed for maximum shop assembly which minimizes field erection time and costs.   We offer natural circulation designs for minimal parasitic power consumption and reduced maintenance of rotating equipment.  Our expert engineering teams review every aspect of the design and incorporate proven design features across all product lines.
