Steam rate means how much mass of steam entering into system per time.........
There are several ways to calculate the .steam consumption rate. First would be to use a heat transfer equation. Another way would be to measure steam directly using flow metering equipment.
Divide heat added to the boiler between feedwater inlet and steam outlet by the kilowatt output of the generator at the generator terminals. Rate expressed in btu. See article.
The disturbance factor in steam blowing is a parameter that says how effective is the steam blowing regarding the pipinginternal surface cleaning process. It is the ratio between density*speed^2 in blowing and normal operation conditions conditions. rudi
The guaranteed heat rate, indicated on performance data table of power plant is calculated in accordance with the following formula: HR = (Qms x Hms - Qfw x Hfw + Qhrh x Hhrh - Qcrh x Hcrh - Qas x Has + Qmu x Hmu) x 3600 / W HR = heat rate [kJ/kWh] W = gross power output [kW] Q = mass flow [kg/s] H = enthalpy [kJ/kg] Subscript: ms = main steam fw = boiler feedwater hrh = hot reheat steam crh = cold reheat steam as = auxiliary steam extraction from turbine cycle for boiler users mu = make up water at condenser

The steam flow rate can be calculated by dividing the mass flow rate of the steam by the specific volume of the steam at the given conditions. This can be determined using steam tables or steam property calculators. The formula to calculate steam flow rate is: Flow rate (lb/h) = Mass flow rate (lb/h) / Specific volume (ft^3/lb)
Steam Rate calculation Formula for Steam Turbine
There are several ways to calculate the .steam consumption rate. First would be to use a heat transfer equation. Another way would be to measure steam directly using flow metering equipment.
The efficiency of a steam turbine is just the ratio of power out to power in, but if you want to be able to calculate it from the basic mechanical design, this is a specialised topic. In the link below is a general description of steam turbines, in the references and additional reading list there are some references that may help you.
the ratio of the distillate mass flow rate to the mass flow rate of the steam used
Robert C. Spencer has written: 'Theoretical steam rate tables--compatible with the 1967 ASME steam tables' -- subject(s): Steam, Tables
a device for controlling the rate of working of machinery or for controlling fluid flow, in particular a handle controlling the supply of steam to the cylinders of a steam engine.
Yes
An example of an energy balance equation for a steam turbine can be expressed as: Input energy (steam flow rate x enthalpy of steam) Output energy (mechanical work done by the turbine heat losses)
Steam curing and water curing are two very different types of curing. Steam curing significantly accelerates the rate of hydration by adding moisture if this is what you need.
