Design pressure for Blowoff Flash Tank - Boiler and Pressure …

16/9/2014 · The standard temperature limitation for drainage to a public sewer system for water is a maximum of 140 deg. F. For example, blowdown water coming from a 150 psi operating pressure boiler is 366 deg. F. The blowdown separator, with the use of the attached aftercooler, is designed to reduce the temperature of the water to at least 140 deg. F. before it is dumped into the sewer.

What is Boiler Blowdown ? - Surface Blowdown - Bottom Blowdown

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Parts and functions of Steam Turbine Power Plant Parts and functions of steam turbine: Rotor Stem chest Casing Over speed trip system Governor system Steam chest and the

Exergy analysis and evolutionary optimization of boiler blowdown …

The optimization results show that temperature and pressure of boiler outlet stream have a higher effect on the exergy efficiency of the system in respect to the other decision variables. Using optimization methods, exergy efficiency of the system reaches to 30.66% which shows a 1.86% augmentation with regard to the situation when a flash tank is implemented.

ASME Blowdown Tanks - Calefactio

26/6/2012 · I've got to define the design pressure of a vessel which receives the intermitent blowdown from a boiler. It is an atmospheric tank, so the normal pressure would be aprox. 1,2 bara (1 + pressure losses in the vent). I would like to know if there is a code or just good practice that states which design pressure should have the vessel.
