摘要： PURPOSE:To form stable flame and restrain excessively rich CO by making a scoop hole, through which a part of secondary air is supplied over the volocity change area of primary air flow, and a seirl air hole in a connected part of a main and a sub-conbmstion chamber, through which a part of secondary air is supplied. CONSTITUTION:A gas turbine burner is provided with a fuel nozzle 3, a sub-combustion chamber 5, and a main combustion chamber 6 and a primary air hole 9 and a swirler 8 are made in the area near the head of the sub-combustion chamber 5, through which air is effected to swirl. Scoop holes 17 out into the burner to make a part of secondary air over the volocity change area of the primary air flow 12 are made in the wall of the sub-combusion chamber near the main combustion chamber 6 and auxiliary swirlers 18 are provided on the internal face expanding from the sub-combusiton chamber 5 to the main combustion chamber 6, which make a aprt of secondary air swirl to supply. Secondary air blown through the scoop holes 17 can run through the primary air flow 12 and be supplied for the flame and swirl 19 fed from the auxiliary swirler 18 can eliminate the low-temperature area so that the required purpose can be attained.

摘要： PURPOSE:To reduce the ineffective operation and to increase the soft processing ability, by compulsively flowing current through the diodes and Zener diodes constituted in matrix and detecting and monitoring the currents. CONSTITUTION:The logic level conversion circuits AMPO and AMP 1 converts the current detected into logic level to photo couplers PHO and PH1, the drive circuit DV drives the transistor Tr for current switching, and it is controlled with the control circuit CNT. The current flowing is detected via the contact a and one diode DO constituted in matrix with the closing of the scanned contact a, and based on the detection, the current flows compulsively via another diode D1 constituted in matrix and the Zener diode ZD. Thus, the current flowing to another diode D1 and the Zener diode ZR is detected and monitored. Accordingly, ineffective operation is made less and the software processing ability can be increased.

摘要： PURPOSE:To perform safe and sure fixation, by providing at one end of an accelerator a head larger than the diameter of a frame inserted part and providing a circumferential groove in optional position at a hole of a frame and inserting the accelerator into the frame hole and deforming the frame. CONSTITUTION:The headed accelerator 15 is tightly fitted into the frame 5 so that the head of the accelerator is not located in the frame. The frame is pressed on both is sides by calking jigs 16, 17. The frame part pressed by a projection of the jig 16 cannot go out and is therefore poushed into the groove of the accelerator 15, thereby filling the groove. Thus, the frame 5 and the accelerator 15 are calked with each other. Since the accelerator is headed, the accelerator connot be pulled out from the frame even if theecalking is imperfect. Therefore, the fixation is safe and sure.
