What is heat rate? Why
What is heat rate? Why is it so important? These are very important questions with critical answers that everyone who manages, operates, or maintains a combined cycle power plant should know.
What is Heat Rate?
Heat rate is the common measure of system efficiency in a steam power plant. It is defined as “the energy input to a system, typically in Kcal (BTU) /kWh, divided by the electricity generated, in kW.” Mathematically:
Efficiency is “a ratio of the useful energy output by the system to the energy input to the system.” Mathematically:
As you can see, heat rate is simply the inverse of efficiency. With that in mind, if you increase plant efficiency, which is good, then you would lower heat rate. What this means is that the lower the heat rate, the better your plant is running and, therefore, the more competitive it is.
As you can see by the equations, efficiency has no units, but heat rate does. That is because with heat rate, you typically are measuring the chemical energy input and the electrical energy output, and this will leave you with the units of Kcal (BTU)/kWh
