Steam locomotive - Wikipedia

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine.These locomotives are fuelled by burning combustible material – usually coal, wood, or oil — to produce steam in a boiler.In most engines, the steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels. . Fuel and water supplies are usually

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

An introduction to steam generation and distribution

By the end of the nineteenth century, the Lancashire and Economic (a coal fired shell and tube unit) boilers were the dominant types for saturated steam. The pack-aged boiler concept was imported to the United Kingdom from the United States of America afterthe Second World War following a visit to that country by a team of

Wastewater - Wikipedia

Wastewater is any water that has been contaminated by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration". Therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities. The characteristics of wastewater vary

Boiler (power generation) - Wikipedia

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.

However, while reducing load, although throttle steam pressure remains unchanged, the throttle steam temperature is kept unaltered down to a load of about 60% in a typical pulverized coal-fired boiler. Below this load it is imperative to reduce the steam temperature for stability of boiler operation. Nozzle control is normally used for this mode.
