Abstract: A self-anchoring expansion gap assembly (42) for refractory lined vessels such as a gasifier (10) includes a substantially annular insulating blanket structure (66, 68) formed of compressible refractory material. A coil of rope (62) formed of relatively incompressible refractory material is positioned proximate an outer periphery of the insulating blanket structure. The expansion gap assembly is placed in an expansion gap of a gasifier, for example, such that the coil of rope aligns with an annular channel (30) formed in the refractory lining of the gasifier at the expansion gap. Compression of the expansion gap assembly locks the coil of rope in the annular channel of the expansion gap thereby resisting vacuum pullout. The coil of rope can be formed as a single coil or a plurality of substantially concentric coils preferably from a single length of refractory rope.
Abstract translation: 用于耐火衬里容器例如气化器（10）的自锚式膨胀间隙组件（42）包括由可压缩耐火材料形成的基本上环形的绝热毯结构（66,68）。 由相对不可压缩的耐火材料形成的绳索（62）位于绝缘橡皮布结构的外周附近。 例如，将膨胀间隙组件放置在气化器的膨胀间隙中，使得绳索的线圈与在膨胀间隙处的气化器的耐火衬里中形成的环形通道（30）对齐。 膨胀间隙组件的压缩将绳索绳索锁定在膨胀间隙的环形通道中，由此抵抗真空抽吸。 绳索可以形成为单个线圈或多个基本上同心的线圈，优选由单根耐火绳构成。

Abstract: The operating life of a fuel injector nozzle (10) for a gasifier is prolonged by shielding the fuel injector nozzle (10) with a preformed protective insulating sheath (70) before the fuel injector nozzle (10) is installed inside a preheated reaction chamber of the gasifier. The thermal insulating sheath (70) has low thermal conductivity and is placed around the fuel injector nozzle body. The thermal sheath (70) can also be positioned to cover a downstream end (16) of the fuel injector nozzle (10) that includes a nozzle portion (40). The thermal insulating sheath (70) is supported by ceramic rope, solder or metal wire and is gradually consumable in the environs of the reaction chamber immediately after the fuel injector nozzle (10) is installed. Before the thermal sheath (70) is consumed, it moderates the temperature rise rate of the fuel injector nozzle (10) while the fuel injector nozzle (10) is being installed in the gasifier.

Abstract: The fuel injector nozzle (10) for a gasifier includes a protective recfractory sheath (70) that is flush mounted at a downstream end proximate the nozzle outlet portion (40). The refractory insert (72) is of annular form to surround the nozzle outlet. The annular refractory member can be a one-piece structure or a multi-segment structure. Whether the annular refractory member is a one-piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locating pins (110) or by thread-like engagement between a projection (144) and a groove (172) that are provided on complementary inter-engaging surfaces of the recess and refractory member. The enduring presence of the annular refractory member prolongs the service life of the fuel injector by protecting the vulnerable surface areas at the downstream end of the fuel injector nozzle that are close to a hot and corrosive reaction zone within the gasifier.

Abstract: A method for facilitating the deslagging of a partial oxidation reactor used to produce syngas is disclosed. The slag comprises vanadium trioxide and a siliceous material that accumulate on the interior walls (17) of the partial oxidation reactor (1) as a byproduction of the syngas production. The deslagging is accomplished by controlled oxidation, wherein the vanadium to glass weight ratio is maintained to at least about 3:2, operating the reactor (1) at a temperature of at least about 2000 degree F, and maintaining controlled oxidation conditions sufficient to convert the vanadium trioxide in the slag to vanadium pentoxide.

Abstract: The fuel injector nozzle for a gasifier includes a protective refractory sheath that is flush mounted at a downstream end proximate the nozzle outlet portion. The refractory insert is of annular form to surround the nozzle outlet. The annular refractory member can be a one-piece structure or a multi-segment structure of preferably not more than four pieces. Whether the annular refractory member is a one-piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locking pins or by thread-like engagement between a projection and a groove that are provided on complementary inter-engaging surfaces of the recess and the refractory member. The retaining structure provided on the annular refractory member and at the recess in which the refractory member is disposed securely maintain the annular refractory protective member in position. The enduring presence of the annular refractory member prolongs the service life of the fuel injector nozzle by protecting the vulnerable surface areas at the downstream end of the fuel injector nozzle that are close to a hot and corrosive reaction zone within the gasifier.
