Convection (heat transfer) - Wikipedia

Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow).Convection is usually the dominant form of heat transfer in liquids and gases.

Compressor - Wikipedia

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.An air compressor is a specific type of gas compressor.. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe.As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while

Particulates - Wikipedia

Particulates also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM), or suspended particulate matter (SPM) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or

Boiler/Burner Combustion Air Supply Requirements and

The amount of air required for ventilation and cooling in the boiler room is determined by the heat loss from the boiler shell or jacket, the boiler piping, breechings, stacks, and any other heat-generating equipment present in the boiler room. Heat loss from the boiler jacket could range from 1/2% to 4% of the boiler output, depending upon

No Heat? How to Diagnose Loss of Heat - Hot Water Boiler

Note: some hybrid or mixed heating systems combine both hot water and hot air to heat a building, such as water to air systems which use a heating boiler (oil, gas, or electric) to heat water which circulates through (and inside of) a heat exchanger (that looks like a car radiator) -

Heat sources. In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.. In a nuclear power plant, boilers called

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.
