Dec 03, 2009 · Key boiler safety features. Boilers have a variety of safety features designed to prevent accidents and keep them functioning at optimal efficiency. Safety valves are the primary safety feature on a boiler. Designed to relieve the pressure generated within the boiler if other systems fail, every steam and water-heating boiler must have at least one safety or safety relief valve of sufficient capacity to …
In most states these laws call for inspection of water-side systems (water level controls and pressure-retaining devices), but not testing of fuel train safety devices. In 26 states ASME CSD-1 (American Society for Mechanical Engineers, Controls and Safety Devices Code for Automatically Fired Boilers) is an adopted code. It mandates actual operational combustion safety systems testing for units up to 12.5 …
Defective safety valves. Obstruction between boiler and valves. Damaged or corroded valve. Level tied down. Valve outlet obstructed. No release of excess pressure. Excessive pressure on the boiler. Boiler ruptured. Loss of life and injury. Damage to assets. Promptly replace or repair safety valve. Remove obstructions. Periodic test of safety valves. PREVENTIVE
Top Ten Boiler and Combustion Safety Issues to Avoid
Mar 15, 2017 · Boiler operators should ensure that the fuel system, including valves, lines, and tanks, is operating properly with no leaks. To prevent furnace explosions, it is imperative that boiler operators purge the boiler before ignition of the burner. Workers should check the fuel to air ratio, the condition of the draft, and the flame to make sure that it is not too high and not smoky.
With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.

pressure. Sudden stressing of a boiler under pressure is dangerous. ALWAYS watch the steam gauge closely and be prepared to cut the boiler in, opening the stop valve only when the pressures are nearly equal. NEVER bring a boiler up to pressure without trying the safety valve. A boiler with its safety valve stuck is nearly as safe as playing with dynamite.
