A combustion system includes a combustor having staging blocks and flashback detection units configured to detect flashbacks occurring in the staging blocks, and a combustion control device configured to stop a supply of a fuel for one of the staging blocks in which a flashback occurs based on a detection signal from one of the flashback detection units. The combustion control device includes a staging processing unit configured to instruct to supply the fuel or stop the supply of the fuel for each of the staging blocks based on a staging pattern in which an operating line is specified and a load adjustment unit configured to reduce an amount of load to a level at which the supply of the fuel for the one of the staging blocks is stopped when the detection signal is input from the one of the flashback detection units.

Combustion control device, combustion system, combustion control method and program

A combustor includes a combustion chamber and an acoustic liner, wherein through-holes through are formed in a wall of the combustion chamber, a plurality of rows of the through-holes is arranged in a lengthwise direction of the combustor, the through-holes of a first through-hole row are shifted with respect to the through-holes of a second through-hole row so that centers of the through-holes of the first and second through-hole rows adjacent each other are staggered in the circumferential direction, cooling grooves are formed so as to avoid the through-holes inside that is sandwiched between the outer peripheral surface and the inner peripheral surface of the combustion chamber, and the cooling grooves include transverse cooling grooves extending in the circumferential direction between rows of the through-holes, and longitudinal cooling grooves extending in the lengthwise direction between the through-holes and connecting the transverse cooling grooves adjacent to each other.

Combustor with acoustic liner

An elevator door system including a landing door, a car door provided on a car, a latch device for locking the landing door when the landing door is closed. The elevator door system also includes a door locking device provided on the landing door composed of a coupling plate for coupling with the car door, an unlocking plate provided in parallel with the coupling plate, and a link for moving the unlocking plate toward the coupling plate. The elevator door system further includes a first linking mechanism for linking the door locking device with the latch device, and a coupling device provided on the car door composed of a pair of coupling rollers for coupling the car door with the landing door. One of the coupling rollers pushes the unlocking plate toward the coupling plate when the car lands the landing floor. A displacement of the unlocking plate caused by being pushed toward the coupling plate by the link is applied to the latch device. The latch device unlocks the landing door when the displacement of the unlocking plate is applied. The coupling device couples the car door with the landing door by pushing the door locking device when the car lands the landing floor and after the landing door is unlocked, and then the car door and the landing door are moved in one unit.
