Steam Pressure Measurement In Boiler


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

Boilers | A new standard in steam measurement Rising

Jan 22, 2010 · Upwards of 60% of the pressure drop across an orifice plate is unrecoverable, contributing to the overall cost to operate the steam measurement system. Newer meters, such as the vortex meter, operate with less than 1 psi of pressure drop — a substantial benefit when accounting for the cost of producing steam.

Steam Boiler Pressure - InspectAPedia

Mar 29, 2011 · The amount of energy required to generate steam with a certain pressure in a closed vessel can be calculated from the enthalpy of water plus the vaporisation heat at the respective pressure. The enthalpy is the difference between boiler water temperature and boiling temperature, multiplied with the specific heat and density.
