Steam Piping Systems - an overview | ScienceDirect Topics

The steam lines are a critical components system in the boiler tower: in particular the main steam and hot reheat lines are made by thick pipes that are necessary to transfer the steam from the top of the boiler to the steam turbine room, generally located at ground level.

Boiler Efficiency and Steam Quality: The Challenge of

For example, if a process of which steam consumption is only 5% of boiler output is turned on rapidly (such as with an on-off valve), the system demand can easily increase by 15% or more until the process reaches a steady state of operation. When a steam valve opens, two problems occur in the boiler. First, steam pressure drops rapidly.

Controlling TDS in the Boiler Water | Spirax Sarco

The water being drained from the boiler is at saturation temperature, and there is a drop in pressure over the orifice almost equal to the whole boiler pressure. This means that a substantial proportion of the water will flash to steam, increasing its volume by a factor of over 1 000.

A SOURCEBOOK FOR INDUSTRY - Energy.gov

Steam is generated in a boiler or a heat recovery steam generator by transferring the heat of combustion gases to water. When water absorbs enough heat, it changes phase from liquid to steam. In some boilers, a superheater further increases the energy content of the steam. Under pressure, the steam then flows from the boiler or steam generator

Applying ASME Boiler Code to Steam Generation Systems

Jan 01, 2013 · (Page 1) The main focus of the ASME boiler code is on power boilers, rather than on petroleum refinery or petrochemical heaters, so definitions are sometimes not clear. Furthermore, it can be difficult to define which authority has jurisdiction over steam generation systems in the CPI. Even in the U.S. This article provides guidance on the requirements for stamping within the ASME code and

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
