High Pressure Washer - Professional and Domestic - Comet Spa

The high pressure washer is a machine that, thanks to a high pressure water jet, removes dirt and incrustations from any solid surface. Water coming from a water source (around 2 bar pressure) is pressurized (up to 500 bar) by means of a piston pump powered by an electric motor or endothermic engine and flows out through a nozzle mounted on a lance, thus succeeding in disintegrating and

Central heating - Wikipedia

In much of the temperate climate zone, most detached housing has had central heating installed since before the Second World War. Where coal was readily available (i.e. the anthracite coal region in northeast Pennsylvania) coal-fired steam or hot water systems were common. Later in the 20th century, these were updated to burn fuel oil or gas, eliminating the need for a large coal storage bin

Installing an energy efficient boiler - Energy Saving Trust

Feb 10, 2021 · Heating accounts for about 55% of what you spend in a year on energy bills, so an efficient boiler makes a big difference. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue (a pipe for extracting fumes and supplying fresh air to the boiler).

Steam locomotive - Wikipedia

How a steam locomotive works, in 100 words ; Coal or oil is directed into the firebox (item 27 in the large diagram below), where it burns at high temperature. The firebox is surrounded by water in the boiler, and many tubes (28) extend from the firebox's front along the boiler barrel (29). Very hot gases travel through these tubes and up the smokestack/chimney (33).
