    Abstract: PURPOSE:To prolong the lifetime of a burner by decreasing wear caused by slurry, by inreasing the fuel passing area by means of moving a control cone forward to the side of an injection port so that the fuel injection speed does not become very high. CONSTITUTION:A cone 13 is designed to be movable to the axial direction 22 of a burner by moving a cone-moving axial shaft 20 by screws and others which are not shown. The passage 6 for atomizing gas 1 such as steam is opened to a mixing part 7a which is a part of fuel passage 15 near an injection port 19. In this case, a swirl flow can be given to the atomized fuel by opening each passage 6 for atomizing gas to the tangential direction of a fuel passage 15. At that time, a supporting plate 21 will not give a bad influence to the swirl of fuel, because it is positioned in the upstream side of the mixing part 7a.

    Abstract translation: 目的：通过减少由浆料引起的磨损来延长燃烧器的使用寿命，通过将控制锥向前移动到喷射口侧面来减少燃油通过面积，使燃油喷射速度不会变得非常高。 构成：锥体13被设计成可以通过螺钉等移动锥形移动轴20而能够移动到燃烧器的轴向22。 用于雾化气体1（例如蒸汽）的通道6向作为喷射口19附近的燃料通道15的一部分的混合部分7a打开。在这种情况下，可以通过打开每个通道6向雾化燃料提供涡流 用于将气体雾化到燃料通道15的切线方向。此时，由于支撑板21位于混合部7a的上游侧，所以支撑板21不会对燃料的涡流产生不良影响。

    Abstract: PURPOSE:To reduce the effect of after air, and to obtain a combustion method reducing NOx without increasing CO and smoke dust in exhaust gas by providing a front section in a furnace with each burner at a lower stage, an intermediate stage and an upper stage and sections higher than the front section with front and rear after air ports and specifying the air ratios of each burner at the lower stage, the intermediate stage and the higher stage. CONSTITUTION:The front after air port 11 is arranged at a section higher than the rear after air port 12. The air ratio of the lower-stage burner 2 is made to reach 0.8-1.0, the air ratio of the intermediate-stage burner 3 to 0.6-0.8 and the air ratio of the lower-stage burner 4 to 0.4-0.6 as the conditions of combustion. The lower-stage burner 2 and the intermediate-stage burner 3 are burnt under approximately the same conditions of combustion as a conventional stage combustion method at that time, but the air ratio of the upper-stage burner 4 is reduced remarkably up to 0.4-0.6, and intermediate products in a combustion reaction are increased. Accordingly, flames generated by the lower-stage and intermediate-stage burners 2, 3 and a flame generated by the higher-stage burner 4 are mixed sufficiently because nitrogen oxide generated by the lower-stage and intermediate-stage burners is reduced by radicals generated by the higher- stage burner.

    Abstract: PURPOSE:To make it possible to detect continuously pressures accurately by providing two pressure detecting branch pipes having strainers respectively from the pipe of a slurry fluid. CONSTITUTION:Two branch pipes 3A and 3B are branched from pipe 2 of a slurry fluid, and strainers 6 are provided respectively for preventing solid components in the fluid from flowing to pressure gauge 1 and are connected to pressure gauge 1 through three-way switching valve 7, and pipes 8A, and 8B branched from washing pipe 8 are connected between strainers 6 and valve 7 respectively. Consequently, one of branch pipes 3A and 3B is used for pressure detection in pipe 2, and the other uses washing liquid from pipe 8 to remove solid components stuck to stariners 6 even if one is detecting the pressure, so that branch pipes 3A and 3B can be prevented from being clogged, and pressures in pipe 2 can be detected continuously.

    Abstract: PURPOSE:To enhance the efficiency of injecting a NOx reducing agent into a combustion chamber by setting an injection pipe at an angle or upright and supplying the agent with steam or the like from the lower part of the pipe followed by spraying. CONSTITUTION:NOx reducing agent injection pipe 4 is put into combustion chamber 1 at an angle of theta or upright. A mixed gas of a NOx reducing agent and steam is supplied to pipe 4 from reducing agent supply inlet 9 at the lower end, and the gas is spray-injected into chamber 1 from a plurality of injection nozzles 5 of pipe 4. By placing pipe 4 at an angle or upright the mixed gas undergoes the force of a rising current due to decrease in gas specific gravity by heating, and the gas evenly spreads to the tip of pipe 4. Accordingly, the gas is sprayed uniformly and smoothly from nozzles 5, enhancing NOx removing efficiency. Cooling water 8 is supplied from cooling water supply inlet 10 at the lower end of pipe 4 to enhance the cooling effect.

    Abstract: PURPOSE:To inject a reducing agent into a high-temperature gas for self-cooling by forming several partitions with baffles located in a path between an inner tube and outer tube, and flowing out the reducing agent from holes in the inner tube, then it is ejected from a nozzle on each partition of the outer tube. CONSTITUTION:An inner tube 5 in which an atomized fluid flows is covered by an outer tube 6 to construct a double tube. The inner tube is equipped with inner tube holes 8 that are equivalent to nozzles 9 on the outer tube 6, and baffles 10 which form several partitions. It is so designed as to separately flow a quantity of atomized reducing agent compatible to capacity of the nozzles 9 into each partition from the inner tube holes 8 for cooling the outer tube 6, and then the agent is ejected from the nozzles into the high-temperature gas.
