ASME CSD-1 Safety Devices CF Controls Fuel Combustion

1

ASME CSD-1 Rules for boilers above 400,000 btu input up to 12,500,000 btu input 9.5hp to 300hp Boilers Open Book Test: ASME CSD-1 Is allowed to be used.

ASME CSD-1-2009 Five Sections

“CG” “CM” “CE” “CW” “CF”

General CG

Combustion CF

Steam Waterside CW

Testing Maintenance CM

Electrical CE

ASME CSD-1 2009 “CF” Three Divisions

Controls need to be provided and operate based upon the burner input rating

Burners 400,000 Btu input and under are exempt (10 Boiler hp, 3 gph oil, 115 kw electric) All boilers must comply with CSD-1 sections CW & CE

Control compliance and operation based upon: 400,000 to 2,500,000 Btu input 60 Boiler hp max. 2,500,000 to 5,000,000 Btu input 120 Boiler hp max. 5,000,000 to 12,500,000 Btu input 300 Boiler hp max. 4
