Question

Write a note on dual pressure combined cycle gas turbine power plant

Answer 1

A gas turbine, also called a combustion turbine, is a type of continuous combustion, internal combustion engine. There are three main components:

An upstream rotating gas compressor;

A downstream turbine on the same shaft;

A combustion chamber or area, called a combustor, in between 1. and 2. above.

A fourth component is often used to increase efficiency (turboprop, turbofan), to convert power into mechanical or electric form (turboshaft, electric generator), or to achieve greater power to mass/volume ratio (afterburner).
