These standards set performance characteristics as well as defining the different types of safety valves that are used: ASME I valve - A safety relief valve conforming to the requirements of Section I of the ASME pressure vessel code for boiler applications which will open within 3% overpressure and close within 4%. It will usually feature two blowdown rings, and is identified by a National Board 'V' stamp.

Steam and feedwater together is called working fluid. The name "steam generator" is also still called "boiler," but modern steam generators in the supercritical class do not involve the "boiling" phenomenon. The fuel-firing equipment of a steam generator should completely burn the fuel used in the furnace to release as much energy

Furnace wall water cooling – eliminates refractory and related maintenance. Gas-tight setting membrane – inhibits dew-point sulfur corrosion and outages caused by gas leaks. Rugged steel-based frame – supports boiler and allows jacking and skidding. Outer lagging – galvanized, weather-tight for outdoor installations. Drum internals – ensure positive circulation, low moisture, high

is the amount of steam, in pounds per hour (lb/hr), that the safety valve is capable of venting at the rated pressure of the safety valve. The safety valve capacity is listed on the data plate attached to the safety valve. For example, if the safety valve capacity is listed as 6900 lb on the data plate, the safety valve can discharge steam at

Safety Valve | Function,types, Construction,Working Safety Valves Functions: Safety valve is used to guard the boiler against the excessive high pressure of steam inside the drum. If the pressure of steam in the boiler drum exceeds the working pressure then the safety valve allows blow-off the excess quantity of steam to atmosphere.

Dead weight safety valve is for safety against excessive pressure building up in a steam boiler. Steam stop valve is mounted on the top of the boiler and is used to open and close the supply of steam for use. Man hole is provided for the entrance of a man inside the boiler shell and is required for cleaning, inspection and repairing of the boiler.
