1/1/2016& 0183;& 32;As a very general rule of thumb, optimum gas yields and quality are obtained at operating temperatures of approximately 595–650 C 1100–1200 F . A gaseous product with a higher heat content BTU/ft 3 can be obtained at lower system temperatures but the overall yield of gas determined as the fuel-to-gas ratio is reduced by the unburned char fraction.Cited by: 10

Solar power - Wikipedia
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics PV , indirectly using concentrated solar power, or a combination.Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam.
Speed control of synchronous machine Electric easy
The synchronous machine speed is controlled by varying the frequency. Speed control of synchronous machine is achieved by voltage fed inverters, current fed inverters or cyclo converter. Speed control is of two types I.e. scalar control and vector control. A scalar control synchronous machine consists of two different modes of operation.

Currently, the most widelyaccepted rule-of-thumb values are an injection rate of 1.5 B/D cold-waterequivalent CWE per acre-foot of reservoir volume and 40% steam quality at thesandface. Because reservoirs respond differently to steam injection, no single valueof steam injection rate or quality can be optimum for all reservoirs and allsteamflood situations.
