Extracted text: Projects 3: Gas turbine operated on Brayton cycle Gas turbine operated on Brayton cycle used for electric utility as separated or combined cycles with steam power plant. Broadly speaking, gas turbine cycle is preferred over steam power plant in power station. Therefore, your head of department asked you to investigate and study the possibility of upgrading the power plant in Project-1 to a gas turbine cycle or a combination of both. However, your head of department asked to deliver a report showing you professional evaluation and assessment for gas turbine cycle efficiency. This report will be used to convince the company board committee. Task.1 Your selection was a gas-turbine power plant operating on an ideal Brayton cycle and according to the manufacturing datasheets it has the following specifications: A pressure ratio of 14.77. The gas temperature is 350 K at the compressor inlet and 1500 K at the turbine inlet. Under the assumption of standard air, perform the following: 1. Gas temperature of the compressor and the turbine exits, 2. Back-work ratio, 3. Thermal efficiency using the formula nth = "quetin and by formula ŋth= 1 – r- -P(k²–1)/k, discuss any differences and explain it. For the gas turbine plant described in Task.1, investigate the principles of operation of a gas turbine plant by considering the following: 1. Construct TS and PV diagram 2. Construct simple sketches showing, all the competent for open and closed gas turbine engine 3. Describe the operating role of each component in the engine and main difference between closed and open gas turbine engine 4. How would a closed gas turbine engine be combined with steam power plant engine.
