Title: Fuel spraying device for gas turbine combustor
Inventor: HAYASHI NORIYUKI
IPC: F23R3/00
Filed: 1990-09-17
Abstract: PURPOSE:To shorten a time, in which a compressor installed in a different place is run, as much as possible and to improve the thermal efficiency of the whole of a gas turbine by a method wherein a part of air fed to a burner is branched, and a steam system is connected to an air system where atomization of liquid fuel is promoted by means of air pressurized by the compressor installed in a different place. CONSTITUTION:A nozzle core 11 through which liquid fuel 101 is atomized is located to the central part of a fuel nozzle 1, the liquid fuel 101 is atomized at a vortex chamber 12, and injected as spray through a nozzle hole 13. A cone 15 to form a spray air flow passage 14 is located to the outer periphery of the nozzle hole. Steam 106 the pressure of which is increased in an exhaust heat recovery boiler 53 produces a high speed swirl by means of a spray swirler 16, the swirl being discharged through the nozzle hole 13. Since atomization is promoted, even when a compressor 54 installed in a different place is stopped, the atomizing characteristics of the liquid fuel 101 is not lowered. Since steam 103 and steam 106 are used for atomization of liquid fuel grains, a mixing state of steam in a region where fuel reaction on the fuel nozzle side in a liner is active is improved and production of NOX is reduced by means of a less amount of steam.

Title: Manufacture of anhydrous and crystal trifluoroacetic acid alkali metal salt
Inventor: RUI AMIE
IPC: C07C51/41
Filed: 1986-10-16
Abstract: A process for preparing alkali metal salts of trifluoroacetic acid in the anhydrous and crystalline state. In a first stage, trifluoroacetic acid is neutralized with an alkaline agent in a medium consisting essentially of an alcohol containing 3 to 4 carbon atoms. In a second stage, the water formed by the neutralization reaction is removed by azeotropic distillation. In a third state, the remainder not removed by distillation in the second stage is treated by adding a hydrocarbon which does not solubilize an alkali metal trifluoroacetate and which forms an azeotrope with the alcohol to separate crystals of anhydrous alkali metal trifluoroacetate.
