    Common auxiliary steam pressure control: Here the steam header pressure is measured in one of two modes and compared with a fixed set point. The deviation this creates is used to drive a PI controller. The output of the controller, through two sets of A/M stations and I/P converters, can regulate the pressure-reducing valves in MS and CRH lines to maintain constant pressure at the common

  • high-pressure steam locomotive - wikipedia

    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 operated …

  • boiler efficiency guide - cleaver-brooks


    Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

    Steam boilers are designed for low pressure or high pressure applications. Low pressure boilers are limited to 15 psig design, and are typically used for heating applications. High pressure boilers are typically used for process loads and can have an operating pressure of 75 to 700 psig. Most steam boiler systems require saturated steam.

    Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

    The auxiliary steam boiler serves as steam separator for the entire system. The system is thus kept in hot condition and is ready to start instantly. If the steam from the exhaust boiler exceeds the steam demand onboard, a steam dump valve automatically dumps the surplus steam to a dump condenser.
