Best answer: What is the function of the combustion chamber used in a turbine engine?

In a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. The combustor then heats this air at constant pressure. After heating, air passes from the combustor through the nozzle guide vanes to the turbine.

What is the function of combustion chamber?

A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the firebox which is used to allow a more complete combustion process.

What is combustion chamber in gas turbine engine?

A combustion chamber is where the fuel is burned at constant temperature with air and gas turbine, where the air is expanded to generate electricity.

What is combustion section in gas turbine?

The combustion section contains the combustion chambers, igniter plugs, and fuel nozzle or fuel injectors. It is designed to burn a fuel-air mixture and to deliver combusted gases to the turbine at a temperature not exceeding the allowable limit at the turbine inlet.

What are the three types of combustion chambers used in a turbine engine?

Types of Combustion Chamber. There are three main types of combustion chamber in use for gas turbine engines. These are the multiple chamber, the tubo-annular chamber, and the annular chamber.

What are three types of combustion?

Here’s a closer look at five types of combustion:

  • Complete Combustion. Complete combustion requires a combination of fuel and oxygen. …
  • Incomplete Combustion. Incomplete combustion occurs when there is not enough oxygen for the fuel to fully react. …
  • Rapid Combustion. …
  • Spontaneous Combustion. …
  • Explosive Combustion.

What is the purpose of multivalve?

In automotive engineering a multi-valve or multivalve engine is one where each cylinder has more than two valves. A multi-valve engine has better breathing and may be able to operate at higher revolutions per minute (RPM) than a two-valve engine, delivering more power.

What are the 3 main component of gas turbine?

Gas turbine overview. The gas turbine has three major sections, namely the compressor, combustor and turbine (although, from a materials perspective, the other major component groups – rotor, casing and auxiliaries – are also of interest).

What is the working principle of gas turbine?

The gas-turbine operates on the principle of the Brayton cycle, where compressed air is mixed with fuel, and burned under constant pressure conditions. The resulting hot gas is allowed to expand through a turbine to perform work.

What is the working principle of a gas turbine engine?

As hot combustion gas expands through the turbine, it spins the rotating blades. The rotating blades perform a dual function: they drive the compressor to draw more pressurized air into the combustion section, and they spin a generator to produce electricity.

What are the three types of turbine blades?

Turbine blades are classified into three types: Impulse, reaction, and impulse-reaction.

What is gas turbine and how it works?

A gas turbine is a combustion engine at the heart of a power plant that can convert natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces the electrical energy that moves along power lines to homes and businesses.

Where is the combustion drain valve located?

A spring-loaded drain valve at the bottom of the combustor outer case through which unburned fuel is drained during an aborted start.

What are two types of fuel used in turbine engines?

The two kinds of fuel most commonly used in General Aviation are Jet fuel and Avgas. As the name suggests, Jet fuel is used mainly to power jet engines, which rely on the powerful thrust of expelled air to drive the plane forward.

What happen in the combustion chamber of a turbine engine?

In a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. The combustor then heats this air at constant pressure. … To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process.

What is meant by a free turbine turboshaft engine?

A free-turbine turboshaft is a form of turboshaft or turboprop gas turbine engine where the power is extracted from the exhaust stream of a gas turbine by an independent turbine, downstream of the gas turbine.
