Calculation of the Theoretical Critical Flow Rate of Saturated Steam
Journal of Engineering for Power, 1982This paper is concerned with the computation of the theoretical critical flow of dry saturated steam through passages over a range of 1 psia (7 kPa) to the critical pressure of 3208.2 psia (22.12 MPa). Two computational methods are used: a theoretical method using ideal gas relations, and a flow maximization method using actual saturated steam ...

Critical Conditions and the Choking Mass Flow Rate in Nonequilibrium Wet Steam Flows
Journal of Fluids Engineering, 1984A theoretical analysis of choking in steady, one-dimensional, nonequilibrium, wet steam flows is presented. It is shown that such a flow becomes choked when the vapor phase velocity attains the frozen speed of sound somewhere in the system. The upstream flow pattern cannot then be altered by small adjustments of the back pressure and the mass flow rate

In Indonesia ginger was usually used as a seasoning for dishes, an ingredient for beverage and a source of herbal medicines. Beside raw usage, ginger can be processed to obtain the essential oil which has many advantages such as proven to be an active antimicrobial and having an antioxidant ability.

Seawater deaeration at very low steam flow rates in the stripping section
Desalination, 2006Abstract The model discussed in a previous work for the simulation of a deaerator to remove the oxygen from seawater in desalination plants has been improved. The conservative character of that model has been revised on the basis of the experimental industrial experience of FISIA Italimpianti S.p.A.

Heat Transfer Analysis of Superheated Steam by Considering the Spraying Flow Rate
Journal of Food Process Engineering, 2016AbstractSuperheated steam (SHS) is widely used in the food industry for heating purposes. However, the effect that operating conditions may have on food quality are not quite clear. Spraying flow rate is an important operating condition of SHS that plays a key role in temperature distributions in food. During food processing, adjustment of the spraying

Test of Two-Phase Mass Flow Rate Instrumentation in Transient Steam-Water Flow
1984A test loop for testing and calibrating two-phase mass flow measuring instruments has been successfully established. A reference two-phase mass flow rate measuring device, the True Mass Flow Meter for 50 kg/s and 15 MPa (TMFM 50),has been tested. The accuracy of this instrument has been investigated by a mass inventory balance. After a drift correction

Energy & Fuels, 2009
Hydrogen production from the catalytic pyrolysis−gasification of polypropylene using a two-stage reaction system has been investigated. In this paper, three important process conditions: water flow rate, carrier gas flow rate, and gasification temperature were investigated in relation to hydrogen production. It is suggested that the water flow rate and

Oxidation of Metals, 2013
Steam oxidation of heat exchanger tubing is of growing interest as increasing the efficiencies of conventional pulverised fuel fired power plants requires higher steam temperatures and pressures. These new, more severe steam conditions result in faster steam oxidation reactions, which can significantly reduce the lifetime of boiler components.
