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.

Types of Boiler Explained: Combi, System & Conventional

A conventional boiler is often found in older homes, but a lot of modern homeowners choose to replace them with a system or combi boiler as they deliver higher water pressure. However, some older properties may not have pipework which can cope with higher water pressure and so need to keep using a conventional boiler system.

Oxygen-blown coal gasification captures CO 2 from gas having a high CO 2 content of about 40% under pressure ranging from 2.5 megapascals to 3.0 megapascals (pre-operation CO 2 capture), so that the gas flow to be treated is lower than the CO 2 content to be captured (post-operation CO 2 capture) from the boiler exhaust gas.

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank

Types of Central Heating Systems

The pressure at the tap of a high pressure heating system is the same as the pressure of the mains which in most cases is a lot higher than you would normally experience. These particular central heating systems are great if you have a high mains pressure to start with but if the mains pressure is low then the system is unsuitable.

How a Coal Plant Works - TVA.com

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
