Similarly, you need to supply heat to change a liquid into a gas, and this is called the latent heat of vaporization. Latent heat is a kind of energy and, although it may seem to be "hidden," it doesn't vanish into thin air. When liquid water freezes and turns back to ice, the latent heat of fusion is given off again.

Chat OnlineBiomass is used for facility heating, electric power generation, and combined heat and power. The term biomass encompasses a large variety of materials, including wood from various sources, agricultural residues, and animal and human waste. Biomass can be converted into electric power through several methods.
Chat OnlineWhy Your Boiler Fires Up Then Turns Off If your boiler is an all-in-one combi boiler and it is turning itself on and off every now and again, this is likely to be what is called its 'Pre-heat' function.
Chat OnlineThe difference between a condensing boiler and a conventional boiler lies in the type of combustion. Indeed, the combustion of natural gas or methane produces heat, and since the CH4 methane molecule contains hydrogen H, the same combines with the oxygen to produce water which, is in the steam state.
Chat OnlineTwo Pipe System - Hydronic Central Heating. The two pipe system is the most commonly used configuration in the installation of hydronic central heating systems. These systems are 'fully pumped', meaning that the circulation of water in the central heating circuit is pumped. Note: Underfloor heating can also be a 'hydronic heating' system.

In one method, thermal steam cracking, the hydrocarbon is diluted with steam and then briefly heated in a very hot furnace, around 850 degrees Celsius, without oxygen. The reaction is only allowed to take place very briefly.
Chat OnlineIn modern power plant, boilers produce steam at a high pressure and temperature. The steam is then piped to a turbine. The high pressure steam impinges and expands across a number of sets of blades in the turbine. The impulse and the thrust created rotates the turbine. The steam is then condensed and pumped back into the boiler to repeat the cycle.
