Steam produced in a boiler is frequently "wet"–that is, it is a mist composed of a saturated water vapor and entrained liquid droplets. The quality of a wet steam is defined as the fraction of the mixture by mass that is vapor. A wet stream at a pressure of 5.0 bar with a quality of 0.85 is isothermally "dried" by evaporating the Get Price

The boiler is 85% efficient, and uses gas on an interruptible tariff charged at £0.01/ kWh (£2.77 / GJ). Steam produced in a boiler by the process of adding heat to the water is often referred to as live steam. The terms live steam and flash steam are only used to differentiate their origin.Get Price
A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate that can vary according to the pressure above the boiling water. The higher the furnace temperature, the faster the steam production.Get Price
Steam engines made use of steam boilers to enable trains to run in the 18th and 19th centuries. The way a steam engine works is extremely similar to a steam boiler. Instead of gas, coal was applied to a fire to produce lots of heat. A boiler full of water was located just behind the fire so the water would eventually heat and evaporate.Get Price
