Steam Generator vs. Steam Boiler | Powerhouse

When it comes to deciding which of these systems is right for your business, the key consideration is simple: output and demand. While steam generators are quicker to start up, they are limited in size as their maximum capacity falls short of a typical watertube boiler. Steam boilers, on the other hand, are designed for long-term industrial use.

4 things to look out for in steam boiler pressure controls

Sep 28, 2016 · The boiler pressure gauge read 12 psi. The boiler operating pressure control was set for 15 psi. Steam was spewing from the boiler feed vent like an old locomotive. I adjusted the operating pressure control to the normal steam pressure. Within a short time, the boiler operated the way it was supposed to and the building had heat.

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).

Temperature of steam versus water in a boiler

Oct 16, 2009 · This water is under line pressure (or pump pressure), which is MUCH higher than the pressure of the steam boiler, usually. At that pressure, the high temperature is below the boiling point in the environment, so the water remains liquid. if it didn't, a heat exchanger wouldn't work because the steam would prevent the thermosyphon loop from flowing.

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 operated at over 1,500 psi (10.34 MPa).

A quick glance at steam tables for 120bar shows this to be 325C saturation temperature, so depending on the degree of superheat required, add it to this temperature. 300 degrees superheat would give 625C, and I believe 800C is not uncommon in 150bar boilers.

Proper Pressure Settings for Residential Steam Boiler

You want as little pressure in the system as is possible so the fact you don't see the gauge move, but you get steam to all of the radiators is a GREAT thing. The boiler must be properly sized and working well. The Pressuretrol should actually be a safety devise and should not have to control the pressure in a system that is properly sized.

The Normal PSI Reading for a Hot Water Boiler System | Hunker

Hot water boiler systems also have a high-limit temperature setting that triggers an automatic shutdown if the water temperature rises above that set point. If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking.

For a boiler producing saturated steam, half-load operation demands no special consideration. However, for a HRSG designed to produce superheated steam, the gas flow and temperature at reduced load might dictate a change in superheater arrangement, a different tube material, and revised thinking with respect to the superheater.
