摘要： PROBLEM TO BE SOLVED: To provide a fine powder-like fuel combustion device capable of providing excellent ignition and combustion performances by sufficiently developing the function of a concentrated/lean fuel separator to eliminate the unbalance of the concentration of fine powder-like fuel (fine powder coal) in the fine powder-like fuel combustion device such as a fine powder coal firing burner having an asymmetrical burner nozzle.
SOLUTION: This fine powder-like fuel combustion device comprises the burner nozzle 1, a fine powder coal supply tube 3, and a wind box 5 forming a combustion supporting air supply passage 4 around the fine powder-like fuel supply tube. A vertical plane passing the axis 8 of the jetting direction of the mixed flow A of fine powder coal and carrying air is tilted without crossing the side face of a furnace at a right angle. The shape of the burner nozzle is laterally asymmetrical with respect to the vertical plane, and a burner nozzle opening face 2 is positioned in the same plane as the side face of the furnace. The concentrated/lean fuel separator 31 is horizontally installed in the burner nozzle or the fine powder coal supply tube. The concentrated/lean fuel separator 31 is installed to be parallel with the side face of the furnace and laterally asymmetric with respect to the vertical plane.

摘要： PROBLEM TO BE SOLVED: To sustain the concentration distribution of pulverized fuel surely while eliminating leakage of auxiliary combustion air by an arrangement wherein a concentration separator disposed at the coupling part of a primary air nozzle and a pulverized fuel supply pipe changes the direction as the jetting direction of the primary air nozzle is changed. SOLUTION: A concentration separator 6 disposed at the coupling part of a primary air nozzle 1 and a pulverized fuel supply pipe 3 is coupled through an appropriate coupling mechanism with the primary air nozzle 1 and the direction of the concentration separator 6 is changed as the jetting direction of the primary air nozzle 1 is changed. The concentration separator 6 structured independently from the primary air nozzle 1 is operable independently and may be constructed to detect the movement of the primary air nozzle 1 and to change the direction thereof while following up the movement of the primary air nozzle 1. A diffuser 11 is disposed in the vicinity of an upstream curve of the pulverized fuel supply pipe 3 in outside direction of the curve.

摘要： PURPOSE: To simplify a burner as a whole by reducing the height of a burner panel in a burner which is adapted to burn a gas mixed with two kinds of pulverized coal, dense and thin. CONSTITUTION: A density separator 13 is provided inside a pulverized coal pipe 05 to form a pulverized coal mixed gas of a high concentration at an outer circumference part and that of a low concentration at the center of one pulverized coal pipe. This reduces a dense mixed gas burner and a thin mixed gas burner to one unit, through two separate burners are used in the prior art.

摘要： PURPOSE:To control a reheat steam temperature and enhance the thermal efficiency of a reheat cycle without using a reheater spray. CONSTITUTION:A vaporizer 2, a low temperature superheater 3, a high temperature superheater 4 and a reheater 5 are laid out in a fluidized bed furnace 1 where a bed height 7a of a common fluidized bed can be controlled by a bed height control device 6. The amount of evaporation of the vaporizer 2 is controlled by means of the bed height 7a while the superheated steam temperature of a high temperature superheater is controlled by means of a superheat spray 17. Furthermore, the superheated steam temperature of the reheater 5 is controlled by changing the temperature of the fluidized bed respectively. In this case, there is installed a shielding plate 22 between the high temperature superheater 4 and the reheater 5, thereby changing the temperature of the fluidized bed of the reheater 5 independently of the fluidized bed temperatures of the superheaters 3 and 4 and enabling the reheat steam temperature to be controlled. The shielding plate 22 is provided with a clearance 23 in its lower part and enables a fluidized material to be transferred.

摘要： PURPOSE:To permit an easy decomposition of nitrous oxides in an unprocessed fluid into nitrogen and oxygen by generating glow discharge plasma between a flat plate electrode and a saw-toothed plate electrode by voltage application to activate the fluid with the plasma. CONSTITUTION:Opposite flat plate electrodes 100 are provided facing each of the upper and lower surfaces having sawlike notches of a flat plate electrode 101 and equally spaced from the latter electrode. The flat plates 102 made of a dielectric consisting of alumina porcelain, etc., are interposed between the electrodes 101 and 100 in contact with the latter. AC electric source 8 or pulse source is connected between the electrodes 100 and 101 to generate glow discharge plasma through which an unprocessed fluid is passed for activation, resulting in an easy decomposition of nitrogen suboxides in the fluid into nitrogen and oxygen. The flat dielectric plate 102 provided on the surface of the flat plate electrode 100 prevents a change from the glow discharge to the arc discharge.
