A gas turbine combustor comprises a cylindrical outer casing having one end closed by a header plate. A combustor liner provided with an inner combustion chamber which is divided into a first-stage combustion region on a side of the header plate and a second-stage combustion region formed on a downstream side of the first-stage combustion region. A first-stage fuel supply unit mounted to the header plate for injecting a first-stage fuel to the first-stage combustion region and a second-stage fuel supply unit mounted to the header plate for injecting a second-stage fuel previously mixed in a lean fuel state. The first-stage fuel supply unit includes a first-stage fuel nozzle assembly, which supplies the first-stage fuel, formed by combining a diffusion combustion nozzle and a pre-mixture combustion nozzle. The pre-mixture combustion nozzle has, at an intermediate portion thereof, a pre-mixing portion for preliminarily mixing the first-stage fuel with an air, and the pre-mixing portion having a diameter in a downstream portion thereof smaller than that of an upstream portion thereof so as to form a pre-mixed flow into a contraction flow. The pre-mixing fuel nozzle of the first stage fuel nozzle assembly is disposed so as to surround the diffusion combustion nozzle disposed in a central portion thereof.

摘要:
A gas turbine combustor for a gas turbine power plant comprises a combustion liner connected to a turbine and provided with a main fuel nozzle assembly and a sub-fuel nozzle assembly for jetting fuel to an inside of the combustion liner through nozzle holes, a base fuel supply line, a main fuel line for supplying a fuel to the main nozzle assembly for premixing an air with the fuel jetted through the nozzle hole for carrying out a lean burning in the combustion liner, and a plurality of sub-fuel lines for supplying the fuel to the sub-fuel nozzle assembly for mixing the fuel with a combustion air for carrying out a diffusion burning in the combustion liner. The main and sub-fuel lines branch off a front end of the base fuel supply line. Distributing valves are incorporated in the main fuel line and at least one of the sub-fuel lines for distributing the fuel into the main and sub-fuel lines and degree of openings of the distributing valves are controlled by a control unit for controlling a fuel distribution ratio. The sub-fuel nozzle assembly includes a swirler provided with swirling vanes at an end portion inserted in the combustion liner for swirling the fuel therein The swirling vanes are provided with a combustion air passage to which the nozzle holes of the sub-fuel nozzle assembly are opened.

A bicycle ergometer includes an eddy current brake having a flywheel rotor assembly including an inner part of iron material having a carbon content of 0.12% or less and a silicon content of 0.35% or less, a stator provided inside the rotor assembly, a plurality of exciting coils provided on the stator, and a power source for energizing the exciting coils. The outer part of the flywheel rotor can be made of concrete. The ergometer includes an input panel for inputting physical attributes of the user, e.g., age and sex, a pulse sensor for measuring the heart rate of the user at rest and during exercise on the ergometer, an arithmetic control circuit for calculating a training program and heart rate range and for controlling the eddy current brake to present a load to the user which will maintain the user's heart rate in a predetermined range. The method of using the ergometer enables a user to select a physical strength program and a weight reduction program with the selected program reflecting the age, sex, and the present physical condition of the user.
