    摘要: The known pulverized coal combustion method including the steps of separating pulverized coal mixture gas ejected from a vertical type coal grinder into thick mixture gas and thin mixture gas by a distributor, and injecting these thick and thin mixture gases, respectively, through separate burner injecting ports into a common furnace to make them burn, is improved so as to reduce both an unburnt content in the ash and a nitrogen oxide concentration in exhaust gas while maintaining an excellent ignition characteristic. The improvements reside in that an air-to-fuel ratio of the thick mixture gas is regulated to within the range of 1-2, while an air-to-fuel ratio of the thin mixture gas is regulated to within the range of 3-6, and the range of a degree of pulverization of the pulverized coal is regulated to 100 mesh residue 1.5% or less. The degree of pulverization of the pulverized coal fed to the distributor is regulated either by adjusting the rotational speed of a rotary type classifier in the grinder or by adjusting the angles formed between classifying vanes, rotating about the axis of the rotary type classifier, and the direction of rotation.

    摘要: Raw coal is caused to fall through a coal feed pipe and onto a table so as to be pulverized by a roll. Fine coal particles and coarse coal particles resulting from pulverization are moved upward between an auxiliary classifier cone and a mill casing by hot air supplied from below the mill casing. The hot air (upward stream) carrying the fine coal particles and the coarse coal particles moves across a space of triangular cross section formed between the inverted conical body of the auxiliary classifier cone and the side wall of the mill casing and is forced through blowoff openings defined between deflector plates so as to flow as a lateral rotative stream toward a rotary classifier. Upon impinging the downward-inclined rotating vanes of the rotary classifier, the coarse coal particles are sprung back toward a lower portion of the auxiliary classifier cone and are separated from the fine coal particles. The fine coal particles separated from the coarse coal particles are ejected out of the roller mill together with the upward air stream through a pulverized-coal eject pipe. Coarse coal particles sprung back toward the lower portion of the auxiliary classifier cone move along the inner surface of the auxiliary classifier cone and fall onto the table so that they are re-pulverized by the roll.

    摘要: The present invention provides a cooling medium flow path for improving cooling efficiency of a cooling medium used for liquid-cooling systems for motors, radiators and the like. The cooling medium flow path according to the present invention is capable of increasing cooling efficiency of a cooling medium by providing magnetic members for generating a magnetic force in a direction substantially perpendicular to the flow direction of the cooling medium so that clusters of a liquid, such as cooling water, antifreeze liquid or the like flowing through the flow path may be finely divided or activated.
