Get PriceA steam boiler is a container in which water is heated to produce steam. The steam boiler has a longer on-off cycle because steam has to be produced each time there is a call for heat. Steam turbines generally require high-pressure steam boilers , so you have the maintenance of the boiler system as well as their turbine to consider.
Get PriceConsider, for example, a 100 BHP boiler operating with 100% make-up water at 60°F and producing steam at 125 psig. In this case, the “from and at 212°F” steaming rate is 3,450 lbs/hr, but the net steaming rate is only 2874 lbs/hr—17% less than the “from and at 212°F” steaming rate.

Get PriceThe boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler’s basic principle is to convert water into steam with heat energy.
