An Overview of Combined Cycle Power Plant

Jun 26, 2020 · The gas turbine and steam turbine are coupled to a single generator. For startup, or 'open cycle' operation of the gas turbine alone, the steam turbine can be disconnected using a hydraulic clutch.In terms of overall investment a single-shaft system is typically about 5 per cent lower in cost, with its operating simplicity typically leading to higher reliability.

Air Source Heat Pump: A Replacement For A Gas Boiler

Air Source Heat Pumps (ASHP) have been suggested as a potential alternative to gas boilers for space and water heating. Whilst currently used mainly for heating properties with no gas connection, the UK Committee on Climate Change (CCC) and the draft Future Homes Standard have even proposed banning gas boilers in new build homes from 2025, by not allowing a natural gas connection.

Ejector Working Principle - Mechanical Engineering Site

Jan 01, 2021 · An ejector is a device used to suck the gas or vapour from the desired vessel or system. An ejector is similar to a vacuum pump or compressor. The major difference between the ejector and vacuum pump or compressor is it had no moving parts. Hence it is relatively low-cost and easy to operate and maintenance-free equipment. Ejector Working Principle

Gas detector - Wikipedia

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.

Steam Boiler | Working principle and Types of Boiler

Feb 24, 2012 · The basic working principle of boiler is very very simple and easy to understand. The boiler is essentially a closed vessel inside which water is stored. Fuel (generally coal) is burnt in a furnace and hot gasses are produced. These hot gasses come in contact with water vessel where the heat of these hot gases transfer to the water and

Gas Turbine Power Plants: Parts and Functions | EE Power

Jun 03, 2020 · Gas turbines operate on Brayton Cycle. 25% of energy production in the world is based on gas-turbine power plants. This percentage will increase further when there is a decrease in energy production using fossil fuels. The efficiency of open-cycles can be increased by up to 38%. Small scale gas turbines can be used to obtain 35-45 MW of energy.

How do heat exchangers work? - Explain that Stuff

May 04, 2021 · Hot water is piped through it from a gas central heating boiler, giving up some of its heat to the air in the room in the process and returning to the boiler for more. This is a sort of heat exchanger because the heat from one fluid (the hot water in the pipe) is being given to another fluid (the cold air in the room) without the two fluids mixing.

3.1 Stationary Gas Turbines

A combined cycle gas turbine is a gas turbine with a HRSG applied at electric utility sites. The gas turbine drives an electric generator, and the steam from the HRSG drives a steam turbine which also drives an electric generator. A supplementary-fired boiler can be used to increase the steam production.

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.
