    摘要： A combustor, in which a flame holding region is formed at a location distant from a pilot burner to avoid burnout of the pilot burner and in which flame holding capability is increased to use a lean pre-mix gas for reducing NOx emission, is provided. The combustor includes a combustion liner having a cylindrical side wall that defines a combustion chamber; and a main burner positioned at a top portion of the combustion liner for injecting an annular pre-mix gas into the combustion chamber to form a reverse flow region at a downstream portion thereof, which region is oriented towards the top portion of the combustion chamber along a longitudinal axis. In this combustor, a pilot burner is arranged at the top portion for injecting a mixture of fuel and air only in a direction confronting the reverse flow region.

    摘要： In the present invention, the extremely complicated setting and control and an extremely expensive optical component (wavelength locker) are not required, and optical output wavelength and optical output power can simply be set and controlled at a moderate price. At least one value for determining a dependence of the optical output wavelength on drive current and device temperature and at least one value for determining a dependence of the optical output power on drive current and device temperature in a light emitting device constituting first means 1 for emitting light are stored in fourth means 4. Fifth means 5 determines drive current or optical output power c and device temperature d, at which both the optical output wavelength and optical output power of the light emitting device are separately specified value b, from a relationship among the drive current, device temperature, and optical output wavelength of the light emitting device, the relationship being determined by the at least one value, and a relationship among the drive current, device temperature, and optical output power, the relationship being determined by the at least one value, and the fifth means 5 gives the drive current or optical output power c and device temperature d as target values to second means 2 and third means 3.
