    摘要: A solid fuel burner is provided with a guide member arranged on an outer circumferential section of a distal end of a first gas nozzle so as to guide a fluid flowing through a second flow passage outward in a radial direction; and a contraction forming member that is arranged on an upstream side of the guide member with respect to the flow direction of the second flow passage so as to reduce the cross sectional area of the second flow passage. An outer diameter of the guide member is formed to be smaller than an inner diameter of an outer peripheral wall of a second gas nozzle. The first gas nozzle, the guide member, and the contraction forming member are configured so as to be integrally attachable/detachable along an axial direction of the first gas nozzle toward the outside of a furnace.

    摘要: Provided are a heliostat calibration, device and a heliostat calibration method that can suppress time-change-dependent control error increases and can reduce calibration frequency. The present invention is provided with: an initial position information acquisition unit that acquires initial position information for a heliostat; a theoretical value calculating unit that calculates from the heliostat initial position information and sun position information a theoretical value that is related to the orientation of the heliostat; a deviation calculation unit that, using as input an actual measured value for the orientation of the heliostat, calculates the deviation between the theoretical value and the actual measured value at least two times a day; and a coordinate calibration unit that, when the deviation exceeds a threshold value, calibrates the coordinates of the heliostat such that the deviation is at or below the threshold value.

    摘要: In accordance with the flow distribution of combustion gas including an unburned portion, an after-air port (AAP) arranged downstream of the two-stage combustion burner can effectively reduce the unburned portion by dividing as appropriate so as to avoid interaction, and by mixing together, two types of after-air having functions of linearity and spreading. As the configuration of this AAP, a primary nozzle for supplying primary after-air and having a vertical height greater than the horizontal width is provided in the center in the opening of the AAP, a secondary nozzle for supplying secondary after-air is provided in the opening outside of the primary nozzle, and one or more secondary after-air guide vanes having a fixed or variable tilt angle relative to the after-air port center axis are provided at the outlet of the said secondary nozzle to deflect and supply the secondary after-air horizontally to the left or right.

    摘要: Provided is an inexpensive and simple solar power system. A solar power system according to the present invention includes: a heat collection apparatus (2, 4); a steam turbine (5), a power generator (16); a superheated steam supply line which supplies the steam turbine with superheated steam generated by the heat collection apparatus; a water supply line which condenses the steam expelled from the steam turbine into water and supplies the condensed water to the heat collection apparatus; a heat storage device (8) which has a heat storage medium; a first line which branches from the superheated steam supply line and which supplies the heat storage device with the superheated steam flowing through the superheated steam supply line; a second line which branches from the water supply line and which supplies the heat storage device with the water flowing through the water supply line; and a third line which supplies the steam turbine with superheated steam generated by the heat storage device. The heat storage device stores the heat of the superheated steam which has flowed through the first line in the heat storage medium, and heats the water which has flowed through the second line with the heat storage medium to thereby generate the superheated steam.
