Cogeneration - Wikipedia

Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time.. Cogeneration is a more efficient use of fuel or heat, because otherwise-wasted heat from electricity generation is put to some productive use.

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

Hot oil heaters and thermal fluids: the complete guide

A boiler (1), to which a burner (4) is fitted and which has a flue or chimney (3) to eliminate combustion gases, heats the heat transfer fluid (in the case of domestic central heating water), which, by means of pipes (5), reaches the consumer appliance (2), (in this example radiators), where the energy is given out and it then returns

Calculation of combustion air required for burning solid

Feb 01, 2020 · The web application determines and displays the values for oxygen and air volumes required for fuel combustion and respectively the flow rates of flue gases resulting from the stoichiometric or excess combustion, respectively, taking into account the elemental composition entered by the user, the excess air coefficient and the fuel flow rate.

Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler
