Internal combustion engine - Wikipedia

An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine.

Water Tube Boilers | Spirax Sarco

The water within the water drum, and the connecting pipes to the other two upper drums, are heated, and the steam bubbles produced rise into the upper drums where the steam is then taken off. The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water …

Water Handbook - Preboiler & Industrial Boiler Corrosion

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

Chemical Treatment Requirements for Steam and Hot Water

Jun 12, 2017 · The maximum size of a longitudinal (long) drum boiler is limited because steam and water circulating in tubes from the front and back headers are connected to the steam drum in circumferential rows. The drum diameter determines the number of tubes that can be connected to the drum and limits the width and, therefore, the size of the boiler.
