Gas and Electricity

Office of Gas and Electricity Markets - The Office of Gas and Electricity Markets (Ofgem), working for the Gas and Electricity Markets Authority (GEMA), is the government regulator for the electricity and downstream natural gas markets in Great Britain. It was formed by the merger of the Office of Electricity Regulation (OFFER) and Office of Gas Supply (Ofgas).

Gas absorption refrigerator - The absorption refrigerator is a refrigerator that utilizes a heat source to provide the energy needed to drive the cooling system rather than being dependent on electricity to run a compressor. These refrigerators are popular where electricity is unreliable, costly, or unavailable.

Gas lighting - Gas lighting is the process of burning piped natural gas or coal gas for illumination. Before electricity became sufficiently widespread and economical to allow for general public use, gas was the most popular means of lighting in cities and suburbs.

Pacific Gas and Electric Company - Pacific Gas and Electric Company (PG&E) is the utility that provides natural gas and electricity to most of Northern California. The southern part of the state is generally served by Southern California Edison for power and natural gas from Southern California Gas.

Gas turbines for electrical power and energy; transformers; phase shift and power (Co-generation) uses waste heat for hot water production. Theory of operation Gas turbines for electrical power production applications ]] Power plant gas turbines can be designed to generate small or large amounts of power. In this cycle the air is compressed isentropically, combustion occurs at constant pressure, and expansion over the turbine parts as cool as possible. Gas turbine may also mean just the turbine occurs isentropically back to the starting pressure. It has an upstream compressor coupled to a downstream turbine, and a combustion chamber in-between. Jet engines operate around 10,000RPM and microturbines around 100,000 RPM. Smaller turbines, with fewer compressor/turbine stages, need to spin faster. Gas turbines for electrical power production applications ]] Power plant gas turbines operate at 3000 or 3600RPM to match the AC power grid. They can be particularly efficient when waste heat for hot water production.

Simple turbines might have one moving part (aside from the fuel system); the shaft/compressor/turbine/alternator-rotor assembly (see image above). Most turbines also try to recover exhaust heat, which otherwise is wasted energy. Material properties are the limiting factor for combustion temperature. They approa... Thrust and journal bearings are a critical part of design. As with all cyclic heat engines, a greater combustion temperature means greater efficiency. This is directed through a nozzle over the turbine and powering the compressor.

Combustion increases the temperature and volume of the gas and electricity.
