Title: Combustor for gas turbine
Inventor: SATOU ISAO
IPC: F23R3/06
Filed: 1981-06-05
Abstract: PURPOSE:To perform an effective reduction with a less air amount, by a method wherein, in a combustion for gas turbine using LNG as fuel, fuel and air are evenly mixed by a first and a second mixing eddy generating means. CONSTITUTION:Fuel 39, such as LNG, is jetted to an inlet of a top combustion chamber 11 from a fuel nozzle 5, combustiom air 41 and fuel 39 are mixed by an air revolving device 6, and the mixture gas is ignited by an ignition plug for burning. In the top combustion chamber 11, the chamber is formed in a smaller diameter than that of a main combustion chamber33, and this promotes the mixture of the fuel 39 and the fuel air 41, and shortens a combustion reaction time. During said combustion, revolving airs 43 and 49 flow from a connecting direction to the inside of each top combustion chamber 11 through revolving air intriducing holes 15 and 18, of which a first and a second mixture eddy air generating means consists, and a part of fuel gas flows backward in the diretion of a fuel nozzle 5 through the force of revolving airs 45, 49. This increases a force of a so-called counter-flow 43 and improves a flame-holding property.

Abstract: PURPOSE:To improve the antirolling characteristics at carrying, by detecting the amount of magnetic tape wound on a supply reel and controlling the compensating characteristics of a feedback control system to the reel motor accordingly. CONSTITUTION:When a VTR enters a recording/reproducing operation and an amount of magnetic tape of a supply reel is still much, the rotating speed of a reel stand 7 is small and a frequency of a signal (a) from a tachometer 8 is low.

When the amount of tape of the supplying reel 7 is decreased and the frequency of the signal (a) from the tachometer 8 is high, the voltage of the control signal (b) from the circuit 9 is increased and the time constant of the circuit 4 is small, allowing to give an optimum compensating characteristic to a feedback controlling system to the reel motor 6. Thus, the antirolling characteristics can sufficiently be improved.
