Boiler - Wikipedia

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..

How to Calculate Gas Consumption in a Gas Boiler Burner?

Natural Gas boiler burners use an approximate conversion factor of 1,000. LP or Propane uses an approximate conversion factor of 2,516. This assumes the burner is less than 100-percent efficient when it converts gas to heat energy, which is different from the efficiency of the device using the heat.

Heat exchanger - Wikipedia

A heat exchanger is a system used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural

HVAC Heat Exchangers Explained - The Engineering Mindset

Sep 15, 2018 · A heat exchanger is exactly what the name implies, a device used to transfer (exchange) heat or thermal energy. Heat exchangers are either given a hot fluid to provide heating or a cold fluid to provide cooling. A fluid can be either a liquid or a gas; Heat always flows from hot to cold; There must be a temperature difference for heat to flow

Flue Gas - an overview | ScienceDirect Topics

This is because the flue gas velocity of x = 0.1 m, which is near the entrance to the convection chamber, is less than that of x = 1.0 m, leading to a smaller heat transfer coefficient and thus a lower flue gas temperature. The flue gas of upward flow carries out heat exchange with the tubes, and the flue gas temperature field also gradually

Condenser (heat transfer) - Wikipedia

In systems involving heat transfer, a condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling. In so doing, the latent heat is released by the substance and transferred to the surrounding environment. Condensers are used for efficient heat rejection in many industrial systems. Condensers can be made according to numerous designs, and come in many

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
