摘要: Fuel is burned in a primary combustion chamber with less than the air required for stoichiometric combustion so that the combustion gases have a high carbon monoxide (CO) and hydrocarbon content and the temperature of the gases is held below that at which significant nitrogen oxides (NO.sub.x) would be produced. The combustion gases are then passed through a secondary combustion zone in which more air is injected into the gas stream to oxidize the CO and hydrocarbons to carbon dioxide (CO.sub.2). The secondary burner comprises a plurality of foraminous tubes through which secondary air is emitted. Combustion in the secondary zone is maintained at a temperature below that at which nitorgen oxides (NO.sub.x) will be produced in significant quantities.

摘要: Fuel and less than the amount of air for stoichiometric combustion are injected into a combustion chamber so that the fuel rich mixture burns as a core in the combustion chamber. The balance of the air for substantially stoichiometric combustion is injected coaxially and rotationally as a sheath or vortex which surrounds the core. Where the core is hot and rich, there is little mixing of the sheath air and core gases and the available oxygen combines preferentially with fuel components other than nitrogen so that little nitrogen oxides are produced. After some heat is extracted from the gases in the core, more complete mixing of the sheath air and core gases occurs. Under these lean and cool combustion conditions, production of nitrogen oxides is also unsubstantial. Means for mixing the gas streams may be disposed adjacent the exit end of the combustion chamber when necessary to promote turbulence and further mixing of the air and hot gases for bringing about complete combustion of any residual combustibles. In the larger combustion systems within long furnaces means of promoting turbulence may not be required to complete combustion.
摘要翻译: 将燃料和小于化学计量燃烧的空气量注入燃烧室,使得富燃料混合物在燃烧室中燃烧为核心。 用于基本上化学计量燃烧的空气的平衡被同轴地和旋转地注射为包围芯的鞘或涡流。 在核心是热和富的情况下,鞘空气和核心气体几乎没有混合,并且可用的氧气优先与除了氮气之外的燃料组分结合,使得产生少量的氮氧化物。 在芯中的气体中提取一些热量后,会发生鞘气和核心气体的更完全混合。 在这些贫冷的燃烧条件下,氮氧化物的生产也是不实质的。 当需要混合气流的装置可以设置在燃烧室的出口端附近,以促进湍流并进一步混合空气和热气体,以使任何残留的可燃物完全燃烧。 在长炉内的较大的燃烧系统中,促进湍流的手段可能不需要完成燃烧。

摘要: A bellows arrangement for forming a gas leakage resistant pressure seal between ceramic heat exchange tubes has an elongated metallic bellows defining a central passageway with first and second ends. A metallic tube passes through the bellows and freely moves with respect to the second end of the bellows while defining a gas chamber between the tube and bellows. Axial expansion of the bellows under the influence of the internal pressure when such pressure is higher than the external pressure which may be the atmosphere acts to apply a force at the interface between the bellows assembly and the ceramic heat exchange tube which is proportional to the internal pressure of the heat exchange tube, thereby accommodating movement of the heat exchange tube and providing a pressure seal that is leak resistant.

摘要: An insulated material comprises a first wall having a surface with a layer of insulation thereover. The insulation is anchored to the wall by a plurality of rods which are each attached to the wall and extends through the insulation. The rods are interlocked at expansion point means which allows expansion and contraction of the rods without permitting movement of the insulation from its position.
