摘要： A combustion apparatus including a mixture feeding pipe for injecting a mixture of pulverized coal for combustion air into a furnace, with the mixture being then ignited. A first gas feeding passage is disposed outwardly of the mixture feeding pipe for feeding oxygen-containing gas into the furnace, with a second gas feeding passage being disposed between the gas feeding passage and the mixture feeding pipe, in a radial direction, for feeding the oxygen-containing gas into the furnace. A projection is disposed between the gas feeding passage and the mixture feeding pipe and extends at an exposed end surface thereof into the furnace beyond an exposed end of the mixture feeding pipe, with the projection being hollow for allowing the oxygen-containing gas to flow within the projection.

摘要： A combustion apparatus including a mixture feeding pipe for injecting a mixture of pulverized coal and combustion air into a furnace, with the mixture then being ignited. A radially outwardly flared flame maintaining ring is provided at a tip end of the mixture feeding pipe, with the maintaining ring being exposed to a reduced atmosphere and to high temperatures due to radiant heat from the furnace. A projection extends into the furnace beyond the flame maintaining ring so as to protect the flame maintaining ring from radiation from inside the furnace thereby suppressing an excessive increase in temperature. Combustion air flows along a surface of the projection so as to provide at oxidized atmosphere. A pulverized coal/air separating member extends within the mixture feeding pipe, and a portion or separation of the flow forcibly occurs is locally formed in a conical end portion of the pulverized coal/air separating member, whereby it is possible to effect a complete combustion in a stabilized manner regardless of the unit capacity and load of the combustion apparatus.

摘要： A burner for pulverized coal has a coal duct for pulverized coal and primary combustion air and a secondary combustion air duct such that the coal and primary air and secondary air mix outside the outlet nozzles of the duct in a mixing zone at which combustion occurs. Coal distribution means in the coal duct create, adjacent the outlet nozzle, at least one outer zone of flow spaced from the coal duct axis and at least one inner zone of flow nearer the coal duct axis. These are means for slowing flow in the outer zone relative to the flow in the inner zone, prior to the mixing zone. To achieve good mixing, and promote NO.sub.x reduction, the coal concentration in the outer zone is higher than in the inner zone. The slowing means may be radially inwardly projecting baffles.

摘要： A pulverized coal combustion burner includes a pulverized coal nozzle, and secondary and tertiary air nozzles provided in concentric relation to the pulverized coal nozzle. A flame stabilizing ring is provided at an outlet end of the pulverized coal nozzle. A separation wall is provided within the pulverized coal nozzle to divide a passage in this nozzle into two passages. A pulverized coal/air mixture flows straight through the two passages, so that recirculation flows of the pulverized coal/air mixture are formed in proximity to the outlet end of the pulverized coal nozzle. As a result, the ignitability of the pulverized coal, as well as a combustion rate, is enhanced, thereby reducing the amount of discharge of NOx.
