  • Up to 1,200 psi
  • A- and O-frame design

The Cleaver-Brooks Open Bottom waste heat boilers are offered in A- and O-frame designs. 

With our many years of custom energy recovery from solid combustors and gasification process, we have integrated the natural circulation design waterwall gas seals from our Max-Fire® Series of boilers and added ash cleanouts and hoppers.

The A-frame has two water drums typically 24” in diameter, while the O-frame has a single water drum 24” – 42” in diameter. This series of boilers is suited for 10,000 – 150,000 of steam flow pressures between 15 – 1,200 psig and 50,000 – 450,000 lb/hr of gas flow at near-atmospheric pressure.

Features: 

  • Welded waterwall construction
  • Once-through gas-side design for lower pressure drop
  • Vertical (top) or horizontal gas outlet conforms to space restrictions
  • Combination of bare and finned tubes provide efficient heat recovery
  • Full-length steam and hot water drums with manways on each end for easy access
