For now, only IRI, ASME CSD-1 (Controls and Safety Devices for Automatically Fired Boilers 1992) and NFPA 8501 (Single Burner Boiler Operation-1992) shall be considered. A typical fuel train has several components, each with a specific purpose which is briefly explained below.
NFPA Standard 85B, "Standard for Prevention of Furnace Explosions in Natural Gas-Fired Multiple Burner Boiler-Furnaces," which was an earlier version of NFPA 8502, Section 2-1.3(b), identified "fuel leakage into an idle furnace and the ignition of the accumulation by a spark or other source of ignition" as one of the most common explosive
Role of fired heater safety systems S afety and risk mitigation have always been, and always will Fuel gas PI PI Fuel gas Pilot gas Combustion air flow applies only to gas-fired heaters and excludes boilers. In contrast to RP 560 Fired Heaters for General Refinery Services, which applies to
a residential dual fuel burner since SunRay kicked off. They had a GC 210 that worked well in mid size residential boilers. A little noisy on gas. The kicker is the control scheme & cost for the gas-oil combo. Though Carlin is getting close w/ their little blue box. Gordon-Piatt makes the S4 which starts @ 1.50 gph & 210 cfh gas.
The list of oil heat safety controls that follows also provides a guide to determining where there are missing or defective "off on reset" safety controls & switches at the Oil Tank & Oil Burner, beginning with electrical shutoff switches for heat or fossil fuel fired appliances and followed by oil line shut off valves.
