Chemical energy
Chemical energy is stored in coal. This energy is transferred as heat and stored in water as steam. The energy in steam is transferred to movement in a turbine and to electrical energy in the turbine. Page: 1  1. 2  2. 3  3. 4  4. 5  5. 6  Back. Useful energy transfer is when the energy is transferred into something that is used for a specific application. For example, boiling a water to make a cup of coffee, in this … case the heat is transferred into something that will be helpful for making the coffee. Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a side effect of the useful energy transfer. These transfers waste energy. Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer.   Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a side effect of the useful energy transfer. These transfers waste energy. Pulverised coal (for better and easier combustion), is burned in a boiler where the Heat Energy is converted to Thermal and Pressure Energy of Superheated Steam. This is then Converted into Mechanical Energy by Driving large Steam Turbines.
