Sep 21, 2018 · The temperature of the final steam is controlled by either controlling the amount of flue gas passing through the superheater coils or slightly overheating the steam, then cooling to the desired temperature by either adding water into the steam-using attemperators-allowing the latent heat of vaporization to cool the steam to the desired temperature-or bypassing …Get Price
Steam boilers are frequently employed in various industrial and domestic applications where saturated or superheated steam is required. Steam generated via steam boilers is put into use for heating, cooking, and reboiling purposes, mainly because of its heat energy. On the other hand, the pressure energy associated with steam primarily finds Get Price
What is a steam boiler? Steam boiler is a unit for generating steam. In this case, the device can give 2 types of steam: saturated and superheated. Saturated steam has a temperature of 100ºC and a pressure of 100 kPa. Superheated steam is characterized by high temperature (up to 500ºC) and high pressure (more than 26 MPa).Get Price

Experiment Of The Marcet Boiler And Boyle's Law - 1196 . For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle's law experiment, it was found that pressure is directly proportional to volume, despite using non-ideal gas for the experiment.Get Price
transferred to the saturated steam to increase its temperature. Steam temperature is normally controlled by spraying water into the steam between the first and second-stage superheater to cool it down. Water injection is done in a device called an attemperator or desuperheater. The spray water comes from the pumpGet Price
