Combustion systems in gas turbines

Combustion systems in gas turbines

Introduction

A gas turbine is an engine designed to convert chemical energy of fuel into some form of useful power such as mechanical (shaft) power or high speed thrust of a jet. The gas turbine consists of a compressor, combustion chamber and turbine.

John Barber may be credited for initial development of gas turbine in 1791.The next important development came in 1872,when Stolze obtained a patent. The first U.S. patent covering a complete gas turbine came on June 24,1895 by Charles Gurtis. The first gas turbine that actually operated was designed and operated in France by Stolze but results were discouraging because of low component efficiencies. Holzwarth gas turbine operated on explosion cycle without precompression.

Brown Boveri must be given credit for pioneering construction of gas turbine to generate electrical energy in power stations. The first Brown Boveri gas turbines were those used to drive the air compressors of the Velox boilers in1927.

British made their first flight with an airplane powered by gas turbine on May 15,1941.Power Jets Ltd. Under guidance of Whittle build the WIA engine designed for thrust of 1450lb. & using air-cooling for turbine.

Rolls Royce developed W2B engine also known as Well land. The Well land was first flown in Meteor airplane on June 12,1943.Germany also produced various jet engines before the end of World War II, like BMW 003, Junkar 004. From 1945 to 1950 numerous companies with a vision on profit started or continued research and development of the gas turbine for many applications.
