It is an excerpt. The gas turbine is a machine that converts fuel energy into mechanical energy like a car engine. The turbine, which takes the compressed air and expands it in its nozzles, operates a generator or compressor with its output shaft.
The supply of compressed air inside the machine is accomplished with an axial or radial flow compressor. Compressed air is sent into a large number of combustion chambers where it is heated by fuel. Here fuel can be a combination of heavy oil, diesel, kerosene, natural gas, gas or liquid fuel. In principle, any type of fuel can be used if the combustion system is properly designed. What matters in gas turbines is not the type of fuel used, but the hot air is obtained. It contains a certain amount of heat that can partially convert into velocity energy in hot air nozzles at about 1200 degrees. The high-speed air gas turbine changes direction in its mobile blades and creates a propulsion force that will make the turbine wheel spin. This event can repeat itself on the 2nd or even the 3rd wheel. Gas turbines are used for several purposes: & Bull; Generator start & Bull; Compressor start & Bull; Operation of aircraft and ships working principle: In principle, a gas turbine is an internal combustion machine, such as a diesel engine or explosion engine. The process followed by this machine consists of air inlet, compression, expansion and exhaust steps. The gas turbine cycle can easily be compared to an internal combustion engine cycle. Atmosphere air is sucked with a compressor and compressed with a pressure of 6 .... 12 bar. The temperature will increase due to compression. The air then passes into the combustion chamber and the fuel mixes with the fuel sprayed by the nozzles. Burning fuel raises the temperature of gas (air + combustion gases) under constant pressure. Hot gases expand throughout the turbine, where mechanical work will be achieved. Some of the work is used to start the compressor and the rest is delivered to the output shaft to be used for other purposes. The big difference of a gas turbine compared to a diesel or explosive engine is that the cycle of the gas turbine is continuous. Here, the process is not interrupted like 2 or 4 stroke engines. Compression includes combustion expansion and exhaust steps. This provides the opportunity to receive a constant torque over the output shaft, which is an advantage over the irregular torque of the reciprocating machines. |

Why is it cleaned. How to clean. I do not know if it is not cleared or not, I wanted to share it when I searched in the search engine.

LUCKYBEN thank you. I am waiting for the reply of friends who have knowledge about the subject |
