Title: Fuel nozzle for combustion of gaseous fuel
Inventor: MASAI TADAHISA
IPC: F23R3/18
Filed: 1993-12-28
Abstract: PURPOSE:To enlarge the range of stable combustion, by a method wherein a flame-holding ring is formed so as to intersect perpendicularly to air-flow and flame-holding fuel flows at the rear of the flame-holding ring. CONSTITUTION:Air-flow 12 flows-in through an opening 13 for main combustion air, following which part of the flow of air is dammed by a flame-holding ring 11 intersecting perpendicularly to the air-flow 12 and having a L-shaped cross section. At this time, the flow of the air peels off at the point part (a) of the flame-holding ring 11, and a vortex occurs to the downstream side thereof. The strength of the vortex depends on the speed of the air-flow 12, and the faster the speed is, the stronger the vortex becomes. Stable flames can be formed by supplying flame-holding fuel to this vortex part through flame- holding gas jets 3 at the rear of the flame-holding ring 11, independent of gaseous fuel 1 through main gas jets. In this way, the range of stable combustion can be enlarged.

Filed: 1987-12-28
Abstract: PURPOSE:To improve overall efficiency by applying DC bias voltage in addition so as to negate the temperature dependence of a gate potential of an output stopping transistor. CONSTITUTION:Switching power supply is such that input voltage Vcc is turned ON/OFF by a switching transistor(Tr) Q103 to convert the input into AC voltage which is sent to an output side through a transformer T101. It is rectified and smoothed by a diode D104 and a capacitor C102, and a difference between divided and detected output voltage value and reference voltage is supplied by negative feedback to the TrQ103 through a TrQ104 through a differential amplifier 10, a triangle wave oscillator 12 and a comparator 14 so as to stabilize the output voltage. At that time, a bias circuit 22 is provided, and is constituted of diode D103 and so on to apply bias voltage to the base of a TrQ102. Accordingly, if an ambient temperature rises, and even if a base-emitter potential falls, the bias voltage also falls as well, so that the temperature dependence can be negated as much as possible.
