What is the wasted energy called when coal is burnt?
The wasted energy when coal is burnt is called waste heat. This is the energy that is not converted into useful work during the combustion process and is released into the environment as heat.
How hot does coal burn and what factors influence its combustion temperature?
Coal typically burns at temperatures ranging from 1,100 to 2,200 degrees Fahrenheit. The combustion temperature of coal is influenced by factors such as the type of coal, the amount of oxygen available for combustion, the size and shape of the coal particles, and the efficiency of the combustion process.
What is the word equation for the combustion of coal?
The word equation for the combustion of coal is: coal + oxygen → carbon dioxide + water vapor.
What is a burnt out piece of coal?
A burnt out piece of coal is one that has already undergone combustion and no longer contains enough energy or fuel to burn effectively. It appears as a charred, blackened fragment that is no longer useful for producing heat or fire.
What is the chemical equation of coal combustion?
The combustion of coal can be represented by the general equation: C + O2 → CO2 This equation shows that carbon (C) in coal reacts with oxygen (O2) to produce carbon dioxide (CO2) as the combustion product.

What are the products of combustion for coal and petroleum?
Complete combustion will result in the production of CO2 and H2O.

How does spontaneous combustion in coal occur and what are the factors that contribute to this phenomenon?
Spontaneous combustion in coal happens when the coal self-heats and ignites without an external heat source. Factors that contribute to this phenomenon include the coal's composition, moisture content, particle size, and ventilation. When coal oxidizes, it releases heat, and if the heat cannot dissipate quickly enough, it can lead to spontaneous combustion.
What does the complete combustion of coal produce?
The complete combustion of organic compounds produces Carbon Dioxide (CO2), Water (H2O), and a residue of any impurities which were present in the coal before combustion. Complete combustion requires a great surplus of molecular Oxygen to occur.
Combustion of coal give out heat?
Yes, when coal undergoes combustion, it releases heat energy as a result of the chemical reaction with oxygen. This heat energy can be harnessed for various applications such as electricity generation or heating.
Where does combustion take place in a coal-burning power plant?
We can probably say the firebox of the boiler is where combustion takes place in a coal-fired power plant.A coal pulverizer feeds the coal into the firebox (burner or combustion chamber) along with forced air. The air-coal mix is ignited in the hot environment, and the heat rises to the coils in the upper part of the boiler. In the bottom of the combustion area we find the ash or slag collector.
