2017 Cleaver Brooks CBEX-700-350-150 ST

Cleaver-Brooks —

• Model: CBEX-F 700-350-150ST
• Serial: T6136-1-1
• National Board #20259
• Year: 2017
• 350 HP (gross output 11,716,000 BTU/hr — the math confirms 350 HP exactly)
• Max working pressure: 150 PSI steam
• Fuel: natural gas only (all oil fields marked NA)
• Max input 14,288,000 BTU/hr · min input 2,858,000 = 5:1 turndown
• 9 ppm NOx — ultra-low NOx burner
• Manifold pressure 8.2" W.C. · inlet pressure 22"–15?" W.C. (second number unclear)

The 9 ppm NOx is your headline. This sets it apart from every used 350 HP firetube on the market — it's sellable in California SCAQMD, Texas, and other strict air districts where a standard 30 ppm unit is a non-starter.
