WARNING: Excessive Pressure Hazard-Volumetric Expansion The heating of water and other fluids causes volumetric expansion. The asso- ciated forces may cause failure of system components and release high temper- ature fluids. This will be prevented by in- stalling properly sized and located com- pression tanks and pressure relief valves.

Dec 25, 2018· Benson Boiler is a high pressure, drum less, supercritical, water tube steam boiler with forced circulation. This boiler was invented in the year 1922 by Mark Benson. This boiler is a super critical boiler in which the feed water is compressed to a supercritical pressure and this prevents the formation of bubbles in the water tube surface.

High-pressure cutoff (steam) - if steam pressure exceeds the high-pressure safety setpoint, shuts off fuel flow to the burner and requires manual reset to resume boiler firing. Make sure the boiler will pass the pressure test. Prior to draining the boiler for cleaning, fill it with water.

Aug 13, 2015· Gas-Pressure Switch. Some boilers require gas pressure switches to meet code compliance. The gas pressure switches are to verify that the gas pressure is within a safe range. If the gas pressure is too low or too high, the burner will not operate correctly. Several years ago, a main gas regulator failed in Chicago.

High Pressure Water Tube Boiler: The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam will reenter the furnace through a superheater to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure.

Steam drum internals for typical type of boiler are shown. The internals include separation devices to assist in separating small droplets of boiler water from the steam. Boiler water in the steam will cause scaling of the superheater and steam turbines.Baffles, chevron types separators and demister pads are used to minimize boiler water carryover.

The high pressure feed water is supplied to the boiler through this valve. This valve opens towards the boiler only and feeds the water to the boiler. If the feed water pressure is less than the boiler steam pressure then this valve remains closed and prevents the back flow of steam through the valve.

The '''operating limit pressure control''' breaks a circuit to stop burner operation on a rise of boiler pressure above a selected setting. It is adjusted to stop or start the burner at a preselected pressure setting. The '''high limit pressure control''' breaks a circuit to stop burner operation on a rise of pressure above a selected setting.

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.
