Working principle of coal power plant

coal power plant

In a coal-fired power plant, a steam boiler is an airtight container that turns water into high temperature steam. It can drive the turbine to rotate so as to generate electric energy. The Shengli boiler is a boiler manufacturer from a coal fired electric plant. So, what is the working principle of a coal-fired power plant? Below, we will introduce the working principle of the coal power plant.

1, generate heat

Before the coal is burned, it is pulverized into fineness of talc. Then mixed with hot air and blown into the boiler's combustion chamber. Suspension combustion, the coal and air is fully mixed, so as to be able to achieve complete combustion and obtain the maximum possible heat.

2. The water turns into steam

High-pressure water pumps deliver water to the interior of the boiler through pipes inside the boiler, converting the water into steam through combustion and heat transfer in the furnace. The steam reaches a temperature of 1000 degrees Fahrenheit at 3,500 pounds per square inch and is delivered to the turbine.

3. steam turbine turbine

The high pressure to drive a series of giant turbine blades makes the turbine shaft turn. The turbine shaft is connected to the shaft of the generator, and the magnet is rotated in an online circle to generate electricity.

4. steam back to the water

After driving the turbine, the steam was sucked into a condenser in the basement of the power plant and cooled indoors. In this important step, millions of gallons of cold water from a nearby water source, such as a river or a lake, are pumped into and through the pipe network that passes through the condenser. The cold water in the pipe condenses the steam into water and returns to the factory for repeated use. The cooling water returns to its source. There is no pollution in the whole process, and the steam water is back to the boiler repeating cycle.

In addition to coal-fired boilers, Shengli boilers also produce sawdust, rice husk, bagasse, natural gas, liquefied petroleum gas, heavy oil and other boilers for power plants all over the world.
