Safety Valve Selection | Spirax Sarco - First for Steam

For steam boilers, a small overpressure is required, usually 3% or 5%. For most other applications, 10% overpressure is required, but according to API 520, for special applications such as fire protection, larger valves with overpressures of 20% are allowed.

Boiler Efficiency and Steam Quality: The Challenge of

Control steam usage to ensure that steam demand does not exceed boiler capacity. Control changes in steam usage to ensure that rapid changes in steam demand will not reduce steam quality. To affect either of the above, use modulating versus on-off valves at steam-use points. Add boiler feedwater with modulating versus on-off controls.

Steam Accumulators and Steam Boiler Response to Load …

Another important factor in instantaneous boiler response is steam chest volume. All steam piping and boiler steam space will maintain a reservoir of steam. If you determine the volume of this area, you can use steam specific volume data to determine the mass of steam stored. For example, if a boiler has a steam space of 3 cubic feet and there are

Steam Accumulators and Steam Boiler Response to Load …

Boiler Ratings and Boiler Load . The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions.

High-pressure steam locomotive - Wikipedia

A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers that
