How to determine thermal efficiency of a power plant?
Because approximately 3,412 Btu/hr equals 1 kW, we can easily determine the thermodynamic efficiency of a power plant by dividing 3,412 by the heat rate. For example, a coal power plant with a heat rate of 10,000 Btu/kWh has a thermal efficiency of 3,412/10,000, or 0.3412 (34.12%).
How accurate is a fuel burn rate?
An industry rule of thumb is that volumetric feeders are accurate to within +/–5% at best, and gravimetric feeders are accurate to +/–2% at best. In practice, I find that the actual error in fuel burn rate measurement can be from 5% to 10%.
What is a sensible heat loss?
Sensible Heat Loss. Sensible heat losses can be thought of as heat you can sense directly with a thermometer. For example, combustion air enters your power plant at ambient conditions, and flue gas is exhausted from the cold end of the boiler air heater at some elevated temperature. The closer the exhaust gas is to ambient temperature, the less sensible heat is lost to the environment.
What is the purpose of combustion power plant?
In a combustion power plant, the fuel is the energy source, and the useful work is the electrical power supplied to the grid, the steam heat supplied to an industrial customer or used for heating, or both.
What is heat rate?
The term “heat rate” simply refers to energy conversion efficiency, in terms of “how much energy must be expended in order to obtain a unit of useful work.” In a combustion power plant, the fuel is the energy source, and the useful work is the electrical power supplied to the grid, the steam heat supplied to an industrial customer or used for heating, or both. Because “useful work” is typically defined as the electricity and steam that is delivered to the final customers, engineers tend to work with the net plant heat rate (NPHR).
Can latent heat loss be changed?
Because latent heat losses are primarily fuel-related, they cannot be easily changed without switching or drying your fuel. (See “ Improve Plant Efficiency and Reduce CO 2 Emissions When Firing High-Moisture Coals ” in the November 2014 issue.)
Is coal used in power plants?

How hot can charcoal get?
As a general rule, you want the steel you’re working to reach about 2,000-2,200°F to be malleable. Meanwhile, lump charcoal is believed to be able to reach temperatures of about 2,000°F at its upper range – which explains why it’s ...
How does combustion produce heat?
In order to produce fire and extreme heat, combustion needs to occur between oxygen, the fuel source, and something to ignite it such as friction or another heat source. Once the fuel reaches ignition temperature, combustion occurs and it burns on its own as long as it has oxygen and fuel for combustion.
What fuel is used in a forge?
Of the various fuel types available, the primary 3 to choose from are lump coal, propane, and charcoal.
How to add air to a forge?

How much energy does a fireplace generate?
How much heat from a fireplace actually heats the home? With a wood-burning fireplace, only between 15% to 30% of the energy generated by the burning wood is turned into heat. Gas fireplaces are much more efficient and can return 75% or even more of their generated energy into heat.
Why is green wood hotter than other woods?
With green wood, the heat generated from the fire will vaporize the water held in the wood before it starts burning the wood itself. So, the drier your wood source, the hotter your fire. The type of wood fueling the fire also plays into the level of heat production.
How to measure heat from a fireplace?
One of the best ways to measure the heat generated by your fireplace is to use an IR (infrared) thermometer. This device measures the radiant energy of a spot it's pointed at. There are many available models but look for one that can measure over 1000 degrees.
What is conductive heat?
Conductive heat occurs when heat is transferred from one object to another by direct contact. You may have experienced this if you’ve ever touched a hot pan on the stove or made a snowball with your bare hands.
Synopsis
Environment
- Fast-forward to 2014, and the scene is radically different. Advanced coal plant emissions controls are the norm, and PRB coal is in use to some extent at most power plants in the U.S., and the Environmental Protection Agency (EPA) has proposed standards for reducing carbon emissions from existing power plants under Section 111(d) of the Clean Air Act. Comprising a variety of po…
Introduction
- This article outlines the basics of plant efficiency and heat rate, such that one can quickly understand where the best opportunity for improvement is for a specific generating asset. It then examines ways in which the 6% NPHR goal might be achieved.
Definitions
- The term heat rate simply refers to energy conversion efficiency, in terms of how much energy must be expended in order to obtain a unit of useful work. In a combustion power plant, the fuel is the energy source, and the useful work is the electrical power supplied to the grid, the steam heat supplied to an industrial customer or used for heating, or both. Because useful work is typically …
Usage
- In the U.S., heat rate is typically expressed using the mixed English and SI units of Btu/kWh. Though confusing at first, this merely indicates how many Btu/hr of energy are required to produce 1 kW of useful work. Other countries commonly use kJ/kWh, kCal/kWh, or other measures. This article uses the U.S. format.
Advantages
- Because approximately 3,412 Btu/hr equals 1 kW, we can easily determine the thermodynamic efficiency of a power plant by dividing 3,412 by the heat rate. For example, a coal power plant with a heat rate of 10,000 Btu/kWh has a thermal efficiency of 3,412/10,000, or 0.3412 (34.12%).
