The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economizer.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.

A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above …
Method for improving the heat rate of a steam turbine operated in a partial-arc mode includes sequential closing of control valves to establish a first arc of admission followed by a reduction of steam pressure to a predetermined level. Additional valves are closed to bring the admission arc to an optimum value and power reduction is thereafter affected by pressure reduction.
Boiler fireside fouling and corrosion problems are mainly restricted to coal and oil fired installations. There are very few reported incidents of corrosion associated with gas fired units, the problem here being mainly confined to overheating due to incorrect operational firing arrangements.

Steam is, however, often used for the heating of industrial buildings where steam-raising plant occurs for process or other purposes. It is also employed as a primary conveyor of heat to calorifiers such as in hospitals, where again steam boiler plant may be required for sundry duties such as in kitchens, laundry and for sterilizing.
This final rule, promulgated under the Clean Water Act (CWA), protects public health and the environment from toxic metals and other harmful pollutants, including nutrients, by strengthening the technology-based effluent limitations guidelines and standards (ELGs) for the steam electric power...

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

These tutorials explain the principles of steam engineering and heat transfer. They also provide a comprehensive engineering best practice guide covering all aspects of steam and condensate systems; from the boiler house and steam distribution system up to the point of use; through the condensate recovery system and returning to the boiler.
Instructor: Lynne Kaley, P.E., Principal, Trinity Bridge, LLC; The details of API’s recommended practices (API 580 Third Edition and API 581 Third Edition) will be presented by recognized industry experts and leaders in the development and use of RBI methodology.
Among the great wonders of the enlightened age is that great source of pure water supply known as the Artesian Well. Brainerd is now the proud possessor of the only one ever tapped in this section of the country. It is known as [Adam] Brown’s Artesian Well and was drilled in the old well site on the above place whic
Everything about fundamental spacecraft design revolves around the Tsiolkovsky rocket equation.. Δ v = V e * ln[R]. The variables are the velocity change required by the mission (Δ v or delta-V), the propulsion system's exhaust velocity (V e), and the spacecraft's mass ratio (R).

7/28/2014 · Steam Generators The boiler or evaporator is that part of the steam generator where phase change or boiling occurs from liquid (water) to vapour (steam), essentially at constant pressure and temperature. The term boiler is traditionally used to mean the whole steam generator.
Heat Recovery Steam Generator HRSG Plant that generates steam using heat from the exhaust gas of a combustion (gas) turbine. Make-up Water Water which is added to compensate for losses of water and steam from the system. Once-through boiler
Steam is often generated to provide heat transfer to a process. There are different modes of heat transfer including conduction, convection, radiation. Find out more about achieving efficient heat transfer, together with calculations and other issues such as heat

All of About Steam Boiler, Heat Exchanger, Energy and Power Generation Failure Modes and Effect Analysis (FMEA) Failure Modes and Effect Analysis (FMEA) is a technique to analyze danger qualitatively that can be used to identify how an equipment, facility or system can be failure and analyze effect that may occur.
Water is stored in the tank of a steam boiler and it is heated by natural gas, propane, coal or an electric element. Once the water is converted to steam, it is collected in an empty tank called a dome. Steam continually collects in the dome and pressure levels within climb higher and higher.
Condensing boilers operate most efficiently when they are operating in condensing mode, which generally occurs when a boiler’s return-fluid temperature is at or below 130 F. In the case of the Beveridge Middle School, the boiler system added heat to the heat pump water loop, which was designed to be maintained between 60° and 70°F during the heating season.
