What is the steam rate?
What is the significance?
The rate of steam flow (kg/h) required to produce unit shaft output (1 kW).
or in other words what amount of steam should be continuously fed into the turbine so that it produces 1 kJ of work per second.
Steam rate is also called specific steam consumption.
(Net work is nothing but the difference between turbine work and pump work.
3600 seconds = 1 hour)
The lower the steam rate the less amount of coal is required to produce unit power.
