Steam Calculators: Boiler Calculator - Energy.gov

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Operating Controls - National Board of Boiler and

Steam boilers require a device which senses steam pressure and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating pressure. A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate.

High-pressure steam locomotive - Wikipedia

2021-1-3 · 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

Characteristics of a High Pressure Boiler

High pressure boilers differ from other methods of energy creation by fuel, emissions, and efficiency. All of these factors have an effect on the equipment's performance and cost. Some of the characteristics of a high-pressure boiler are listed below: Power of Steam: Steam is formed when water expands 1600 times.

Introduction to Steam Distribution | Spirax Sarco

A kilogram of steam at a higher pressure occupies less volume than at a lower pressure. It follows that, if steam is generated in the boiler at a high pressure and also distributed at a high pressure, the size of the distribution mains will be smaller than that for a low-pressure system for the same heat load. Figure 10.1.2 illustrates this point.

Ideal Steam Generation and Distribution Pressures

Steam should be generated from the boiler at rated pressure for best steam quality. The specific volume of steam at higher pressures is lower and hence steam can be distributed through smaller sized steam pipes. This results in reduced radiation losses and lower capital investment.

The HPT exhaust stands for that piping section, where, the steam outlet from both the HPT and the HP bypass system comes and joins. Therefore, it is obvious that CRH steam may be generated even when the HPT may not be in operation and, as a combination of both and depending on the load, the CRH steam pressure at the HPT outlet may vary.
