Steam generator feed processing
Steam generation, control, and quality for feed manufacturing
Steam Boiler When steam is generated, pure water vapor is discharged from the boiler. Since water contains solids, the concentration of dissolved and suspended solids increases in the remaining boiler water as steam evaporates. To maintain optimum steam generation and boiler efficiency, a maximum allowable concentration limit for each solid component in the boiler water exists. To prevent exceeding these limits, boiler water is withdrawn and discarded, while feed water is added to dilute the solids concentration. This process is known as boiler blowdown (or bleedoff). Boiler blowdown is either intermittent or continuous (Murphy, 1994). If the blowdown is intermittent, the boiler water is allowed to concentrate until the maximum level is reached. A valve is opened for a short time (e.g., open the valve for 3 s, close it for 3 s, open it again for 3 s, then close it again), while boiler water is withdrawn and feedwater is added. If no chemical analysis of the water is used as a guide, blowdown should occur at least once every 24 h. The boiler …

Steam Power Station: Components, Application, and Working Mechanism …
A furnace, steam turbine, generator, and other auxiliaries make up a steam power station. The boiler produces steam at a high temperature and pressure. The steam turbine is a machine that transforms steam's heat energy into mechanical energy. The mechanical energy is then converted into electric power by the generator.

Steam Calculators: Boiler Calculator
17/3/2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
