What is Heat Rate?

Heat rate is a term commonly used in power stations to indicate the power plant efficiency. The heat rate is the inverse of the efficiency: a lower heat rate is better. The term efficiency is a dimensionless measure (sometimes quoted in percent), and strictly heat rate is dimensionless as well, but often written as energy per energy in relevant units. Heat rate in the context of power plants can be thought of as the input needed to produce one unit of output. It generally indicates the amount of fuel required to generate one unit of electricity.

How to Calculate Heat Rate?

Heat Rate calculator uses Heat Rate=Steam Flow*Specific Heat Capacity*Temperature Difference to calculate the Heat Rate, Heat rate is the amount of energy required by an electrical generator or a power plant to produce a one-kilowatt hour of electricity. Heat Rate and is denoted by Q symbol.

How to calculate Heat Rate using this online calculator? To use this online calculator for Heat Rate, enter Steam Flow (m), Temperature Difference (dT) and Specific Heat Capacity (Cp) and hit the calculate button. Here is how the Heat Rate calculation can be explained with given input values -> 2510.4 = 30*4.184*20.

FAQ

What is Heat Rate?
Heat rate is the amount of energy required by an electrical generator or a power plant to produce a one-kilowatt hour of electricity and is represented as Q=m*Cp*dT or Heat Rate=Steam Flow*Specific Heat Capacity*Temperature Difference. Steam Flow is the rate by which steam flows to produce a one-kilowatt hour of electricity, Temperature Difference is the measure of the hotness or the coldness of an object and Specific Heat Capacity is the heat required to raise the temperature of the unit mass of a given substance by a given amount.
How to calculate Heat Rate?
Heat rate is the amount of energy required by an electrical generator or a power plant to produce a one-kilowatt hour of electricity is calculated using Heat Rate=Steam Flow*Specific Heat Capacity*Temperature Difference. To calculate Heat Rate, you need Steam Flow (m), Temperature Difference (dT) and Specific Heat Capacity (Cp). With our tool, you need to enter the respective value for Steam Flow, Temperature Difference and Specific Heat Capacity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
