Steam Boiler Feed Pumps & High Pressure Boiler Feed Water

Industrial boilers, for example on board a marine vessel, in a large industrial factory or power plant, are fed either fresh water or steam by a high pressure boiler feed pump. As the water or steam is fed round a system, they are sometimes referred to as boiler circulation pumps. As taking suction from a condensate system is a high pressure

conventional power generating stations and consists of a heat source (boiler) that converts water to high pressure steam. In the steam cycle, water is first pumped to elevated pressure, which is medium to high pressure, depending on the size of the unit and the temperature to which the steam is eventually heated.

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

Catastrophic tube failure engulfs boiler building in high

Oct 12, 2018 · Incident overview A severe tube rupture occurred on a high pressure steam boiler which was operating at 750 pounds per square inch shortly following a warm-up period on start-up. A catastrophic tube failure caused a release of a significant portion of the 40,000 liters of water in the boiler in approximately one minute. The inside of the entire four storey boiler building was engulfed in high

Thermal power station - Wikipedia

The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38%, with state-of-the-art fossil fuel plants

Supercritical steam generator - Wikipedia

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 the critical pressure – 22 megapascals (3,200 psi).Therefore, liquid water immediately becomes indistinguishable from steam.

Surface Condenser in Thermal Power Plant | Watco Group

Good steam condenser performance contribute a lot to total thermal power efficiency. As it was mentioned above, it allows to keep high condenser vacuum and avoid boiler tubes failures which results in high energy conversion. For maintaining clean condenser tubes at all times consider the use of an automatic tube cleaning system like EQOBRUSH.

Thermal Oil Boilers - High-Temperature Heaters based on

In thermal oil boilers, a special oil-based thermal fluid is used as the heat carrier - instead of water or steam. This thermal fluid - also called heat transfer fluid (HTF) - operates at atmospheric pressure all the way up to above 300°C. Comparing this to water and steam, this would require a corresponding steam or water pressure of above 85

Boiler Cycling Considerations - Babcock

A second method of reducing thermal shock is to permit the economizer to reheat during the idle period and then to provide higher temperature feedwater for restart. This can occur by pressurizing a high-pressure heater with steam from an auxiliary source or from the drum of the unit.

Low Pressure Steam Vs High Pressure Steam - Miura Boiler

Low-Pressure Steam. Low-pressure boilers operate at a lower pressure and reach lower temperatures than high-pressure steam boilers. Water in low-pressure boilers is not heated beyond 250ºF, and the steam pressure does not exceed 15 psi (pounds per square inch). Low-pressure steam can be more economical to produce than high-pressure steam, as

Don't Let Thermal Shock Harm Your Steam Boiler! - Clarity

Let's talk about a potentially serious problem that is sometimes overlooked… thermal shock in your steam boiler. Introducing cool water into a piping-hot, metal pressure vessel is never a good idea, but there are facility operators out there that do not know the consequences of this action or simply do not take it seriously enough.
