The temperature control, single and common to both the high- and low-capacity PRV, is the same as discussed in clause no. 10.4.1.5. However, if necessary, the temperature control for each high- and low-capacity PRV can be provided. In case of combined PRDS design, there shall be two such temperature …

General Boiler Information. 1 boiler horse power is about 42,000 BTUs of INPUT. 1 pound of steam is about 1,200 BTUs of INPUT fuel, and about 1,000 BTUs at the point of use, depending on the pressure of the steam. Low pressure steam is considered to be up to 15 psi; high is generally 100 psi and higher.

Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C
Get a QuoteSteam generators, like the GHGA, MHGA, OAB or HGA type routinely offer over 95% efficiency even to 1000°C and beyond (a temperature unimaginable for boiler steam). Temperature Limitations – Industrial boilers are temperature limited by pressure. To obtain higher temperatures, higher pressures are required. Not so for steam generators.
