Which kind of fuel can be burn in a gas turbines?
Fuels derived from other fuels, such as methanol from natural gas, coal or wood are acceptable under certain circumstances, but it is more efficient to burn the fuel from which it is derived. HOW CAN THESE FUELS BE USED? Wood can be used as a fuel in two ways in a gas turbine, as discussed below: Wood Gas.
Can be used as fuel in gas turbines?
Explanation: Natural gases,petrol,diesel etc can be used as fuels in gas turbines. Gas turbines requires liquids with high specific heat as fuels.
Which fuel is used in turbine?
Customarily, combustible fuels for gas turbines encompass natural gas, process gas, low-Btu coal gas and vaporized fuel oil gas (Boyce 2002). Natural gas is the most preferred conventional fuel for propulsion of gas turbines.
Which of the following is not used in gas turbine power plant?
2. Which of the following is not used in gas turbine power plant? Explanation: Natural gas itself or mixture of natural gas and air is used as working medium in gas turbine power plant. Condenser is a device or arrangement used to condense low pressure steam already used by turbine.
Why is liquid fuel better than gas fuel?
Though it has a much lower flash point than fuels such as gasoline, it is in many ways safer due to its higher autoignition temperature and its low density, which causes it to dissipate when released in air.
Can gas turbines use diesel?
Most common ones are naphtha, kerosene, and diesel fuels, which normally can be used as is or with minor cleanup. Oils: Includes crudes and other refined residuals that are heated to acceptable levels to enable the needed viscosity for gas turbine combustion.
Why is Pulverised coal used Mcq?
Why is pulverised coal used? Increased calorific value of coal.
How is pulverized coal used to generate electricity?
In this technology, pulverized coal is injected to combust in a furnace in the presence of a controlled level of air. The heat generated is used to produce high-pressure steam driving a steam turbine to generate electrical power.
What is special in a coal fired power plant?
Preparing the coal for firing or pulverizing. This is what is special in a coal fired power plant, especially large thermal power plants. Burning the coal in the combustion process to release the energy in the fuel. Why Pulverizing?
What is the difference between Pf and SC pulverized coal?
Therefore, replacing old pulverized fuel (PF) plants with SC pulverized coal plants has the potential of reducing emissions by 10–25\% [15]. Pulverized coal (PC) combustion is presently the system of choice for coal-fired power-generating plants.
How much coal does a power plant consume?
Before going into the details, let us look at the quantity of coal processed in a power plant. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal.
