12-11-2015· Since the heat rate tells us how much fuel is needed to generation one unit of electricity, we can use the heat rate to calculate the variable fuel generation cost once we know the cost of fuel. Suppose gas costs $3/MMBtu. If a unit is a combined-cycle gas unit with a heat rate of 7 MMBtu/MWh, then the variable fuel cost of generation is:
Heat Calculator . Here is a simple Heat capacity calculator to calculate the heat generated, measured in Joules, using the values of specific heat, mass and change in temperature. The heat capacity is the amount of heat needed to raise the temperature by 1 degree.
17-07-2007· However, I will resist the temptation to do an explicit calculation for you. But the power (lets use the term heat from now on) it requires depends on what it is heating. If you consider water, can you calculate the amount of heat (in joules) it requires to bring the water to a boil (100 Celsius degrees) from a room temp. of 20 Celsius degrees?
Calculating the Amount of Steam. If we know the heat transfer rate - the amount of steam can be calculated: ms = P / he (4) where. ms = mass of steam (kg/s) P = calculated heat transfer (kW) he = evaporation energy of the steam (kJ/kg) The evaporation energy at different steam pressures can be found in the Steam Table with SI Units or in the ...
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 is a type of energy, so BTU can be directly compared to other measurements of energy such as joules (SI unit of energy), calories (metric unit), and kilowatt-hours (kWh). 1 BTU = 0.2931 watt-hours. 1 BTU = 0.0002931 kWh. 1 kWh ≈ 3412 BTU. BTU/h, BTU per hour, is a unit of power that represents the energy transfer rate of BTU per hour.
