Mell Which fuel is not used in thermal power plant?
For option (B) – Uranium is radioactive in nature. It is used in nuclear power plants where the process of nuclear fission is used to break Uranium into lighter elements and energy is released in the process. However it is not used as fuel in thermal power plants.
Can we use alcohol as fuel?
Alcohol type of fuels is alternative to petroleum-based fuels due to reduced greenhouse gas emission, toxic exhaust emission and enhancement of overall energy efficiency. Moreover, they are convenient for internal combustion engines due to their high octane rating, burning velocities and wider flammability limits.
What type of fuel is commonly used in a thermal power station?
Thermal power plants mainly uses solid fuel such as anthracite coal (Superior quality coal). In majority thermal power plants, bituminous coal also used.
Can alcohol be used for CI engine?
Various alcohols are used as fuel for internal combustion engines. The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
Which type of oil is used in thermal power plant?
・In order to satisfy environmental regulations applicable to power stations, KEPCO use mainly super-low-sulfur crude oil (with a sulfur content not exceeding 0.1%) to ensure fewer sulfur oxide emissions. Heavy oil is also used as a combustion aid.
Why alcohols Cannot be used in CI engines?
Explanation: Alcohols have high self-ignition temperature and low latent heat of vaporization. That is why they cannot be used in CI engines.
Why are thermal power stations different from other power stations?
The greatest variation in the design of thermal power stations is due to the different heat sources; fossil fuel power generation, though nuclear heat energy, solar heat energy, biofuels, and waste incineration are also used. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy.
How are heat exchangers used in thermal power stations?
Heat exchangers may be used where the geothermal steam is very corrosive or contains excessive suspended solids. A fossil fuel steam generator includes an economizer, a steam drum, and the furnace with its steam generating tubes and superheater coils.
How is steam used in a thermal power plant?
The steam activates a turbine which, in turn, drives an alternator to produce electricity. Combined cycle gas power plants (or steam-gas turbine plants): these combine a gas turbine and a traditional thermal plant to generate electricity. Unlike conventional thermal power plants, the residual energy of the gases is used for another cycle.
What kind of fuel is used in thermal power plants in India?
A power generation plant mainly consists of alternator runs with help of steam turbine. The steam is obtained from high pressure boilers. Generally in India, bituminous coal, brown coal and peat are used as fuel of boiler.
