    • In a porous filter, dust that has been collected from a gas through a filter group installed in a vessel body onto filter surfaces is removed from the filter surfaces by backwashing in which the supply and stoppage of a high-pressure gas ejected toward porous filter elements are repeated by means of a valve operation. Backwash tanks having upstream backwash valves and downstream backwash valves are installed in backwash pipes through which the high-pressure gas is guided from high-pressure-gas supply equipment to backwash nozzles for ejecting the backwash high-pressure gas toward the filter group to form a backwash high-pressure-medium supply line. The outlet pressure of the high-pressure-gas supply equipment is set to “1/critical pressure ratio” or more times a filter inlet gas pressure so that the flow speed of the high-pressure gas ejected from the backwash nozzle is the speed of sound or higher.

    • A burner for an entrained bed gasifier is provided in which a stable ignition is accelerated in the vicinity of a fuel jetting port and a good combustion state is maintained. A fuel (1, 3), such as coal and char etc., and a portion of a gasifying agent (2, 4, 5) are premixed in a burner before they a charged into a gasifier. The burner includes a triple tubular member including an outer tubular portion, an intermediate tubular portion, and an inner tubular portion. A seal gas tube is positioned within the inner tubular portion. At the time when the fuel, such as coal and char etc., and a premixing gas (a portion of the gasifying agent) are charged into the burner, at least any one of the fuel, such as coal and char etc., and the premixing gas is charged in a tangential direction relative to the burner central axis so as to be given a swirling directional velocity component.
    • 提供一种用于夹带式气化器的燃烧器,其中在燃料喷射口附近加速稳定的点火,并保持良好的燃烧状态。 燃料(1,3),例如煤和炭等,以及一部分气化剂(2,4,5)在燃烧器中充入气化器之前被预混合在燃烧器中。 燃烧器包括一个三重管状构件,其包括外部管状部分,中间管状部分和内部管状部分。 密封气管定位在内管状部分内。 当燃料(例如煤和炭等)和预混合气体(一部分气化剂)装入燃烧器时,至少任何一种燃料如煤和炭等,以及 预混合气体相对于燃烧器中心轴线在切向方向上充电,以便得到旋转的方向速度分量。
