Get PriceIn general steam heating is used to change a product or fluid temperature maintain a product or fluid temperature a benefit with steam is the large amount of heat energy that can be transferred the energy released when steam condenses to water is in the range 2000 2250 kjkg depending on the pressure compared to water with 80 120 kjkg with temperature difference 20 30 o c
Get PriceThe second step is to calculate the cost of steam at lower pressure levels this is not easy as the cost depends upon the path that the steam follows from the point of generation to the point of use lowpressure steam that is produced through a pressure letdown station usually a pressurereducing
Get PriceThis article provides calculation methods for correlating design flow rate and pressure loss as a fluid passes through a nozzle or orifice nozzles and orifices are often used to deliberately reduce pressure restrict flow or to measure flow rate discharge coefficient gravitational acceleration change in fluid head ratio of specific heats
Get PriceHigh pressure operation as may be required with conventional steam heating this may be reflected in the design and manufacturing costs of the dryer furthermore in addition to the methods listed above oil or gasfired indirect heat exchangers can also be used in general dryers are either suitable for batch or continuous operation
Get PriceSteam is often generated to provide heat transfer to a process modes of heat transfer conduction convection radiation within or between media are explained together with calculations and other issues such as heat transfer barriers methods of estimating steam consumption how to calculate steam requirements for flow and nonflow
