OBSERVING BOILER SAFETY RULES - IDC-Online

trying the safety valve. A boiler with its safety valve stuck is nearly as safe as playing with dynamite. ALWAYS lift the valve from its seat by the hand lever when the pressure reaches about three-quarters of popping pressure. NEVER take it for granted that the safety valves are in proper condition. The power plant is no place for guesswork.

DRAFT BOILER/FEEDWATER GUIDELINES

pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

Boiler safety | Best practices for installing safety

Apr 26, 2010 · The safety valve set point should provide a differential between operating and set steam pressures of at least 20%. The total steam capacity of a safety valve downstream of a steam pressure control valve at the set point must exceed the steam control valve's maximum steam flow capacity (largest orifice available from the manufacturer) if the steam valve fails open.

Control Valve Basics: Sizing and Selection

CONTROL VALVE BASICS – SIZING & SELECTION Introduction A control valve is a power operated device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from the controlling system. Control valves may be broadly classified by their function as "on-off" type or "flow regulating" type.

Selection and Sizing of Pressure Relief Valves

Safety valves are commonly tested by lifting the safety valve try lever.. 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.
