摘要： A combined, integral steam generator coal gasifier includes a vertically elongated, all welded, gas tight enclosure with a burner zone having a double pitch sloping furnace floor and a slag tap extending therethrough. Successive zones located above the burner zone are provided with appropriate tube materials for conveying synthesis gas produced by the coal gasification process. A multi-pass convection pass zone having upflow and downflow passes is located at an upper portion of the enclosure and contains a plurality of superheater (primary and secondary) as well as economizer heating surfaces which extract heat from the synthesis gas to produce steam. An ash remover is connected to the outlet of the convection pass zone to remove ash from the synthesis gas exiting from the convection pass zone. The slag tap located at the bottom of the burner zone communicates with a slag tank or a drag chain deasher for receiving and removing slag from the burner zone.

摘要： A multi-cylinder air delivery port for introducing air into a fossil fuel-fired boiler and auxiliary equipment. The air delivery port is generally comprised of a linearly translatable and rotatable bundle of open ended cylinders that allow air to be injected with a directional and/or swirling flow pattern without the use of louvered damper blades and spin vanes of conventional air delivery ports.

摘要： An integrated air foil and ammonia injection grid provides a plurality of air foils across a flue conveying flue gas. Each air foil has a leading curved edge and a tapered, pointed, trailing end. At least one injection pipe is positioned inside each air foil, and has at least one nozzle for injecting ammonia into the flue gas flowing across the air foils. Preferably, plural injection tubes are provided and positioned one behind the other in each air foil, and each injection tube in a given air foil has a length different than a length of the other injection tubes in the same air foil. A longest injection tube in a given air foil is located furthest downstream and proximate the tapered trailing edge and a shortest injection tube in the same air foil is located furthest upstream, remaining injection tubes in the same air foil being progressively shorter the further upstream any injection tube is located. Apertures may be provided on opposed lateral sides of the air foils for introducing a gas flow into the flue gas passing across the air foils. Ammonia flow to each injection pipe may be individually controlled.
摘要翻译： 集成的空气箔和氨注入栅格在烟道输送烟气中提供多个气翼。 每个气翼具有前导弯曲边缘和锥形尖尖尾端。 至少一个喷射管位于每个气翼内部，并且具有至少一个喷嘴，用于将氨注入流过气翼的烟道气中。 优选地，在每个空气箔中设置多个注入管并且彼此并排定位，并且给定的空气箔中的每个注入管的长度与同一个空气箔中的其它注入管的长度不同。 在给定的空气箔中最长的注射管位于最下游并且靠近锥形后缘，同一空气箔中的最短注入管位于最上游，同一空气箔中的剩余注入管在进一步上游任何注射 管位于。 孔可以设置在气翼的相对的侧面上，用于将气流引入穿过气翼的烟道气中。 可以单独控制每个注入管的氨流量。
