    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. Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector.The terms cogeneration and trigeneration can also

    Central heating - Wikipedia

    A steam heating system takes advantage of the high latent heat which is given off when steam condenses to liquid water. In a steam heating system, each room is equipped with a radiator which is connected to a source of low-pressure steam (a boiler). Steam entering the radiator condenses and gives up its latent heat, returning to liquid water.

    Electricity Generation using Steam Turbines

    Steam turbine systems are essentially heat engines for converting heat energy into mechanical energy by alternately vaporising and condensing a working fluid in a process in a closed system known as the Rankine cycle. This is a reversible thermodynamic cycle in which heat is applied to a working fluid in an evaporator, first to vaporise it

    Complete Combustion - an overview | ScienceDirect Topics

    Complete combustion of hydrocarbons (without impurities) in the presence of enough oxygen produces water vapor and carbon dioxide. Separation of water vapor from the gas stream is simple; condensation can provide the suitable separation. In precombustion technologies, combustion is made using pure oxygen (up to 97% purity); however, a small amount of nitrogen and argon remains.

    - Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70 degrees C (158 degrees F), and Legionella cannot survive at that temperature. - Atomizing humidifiers use mechanical devices or pneumatic air to create a water mist that evaporates into the air stream.
