摘要： A counterweight link rod incorporates a counterweight lifting lug to provide a safe and easily usable means to lift a counterweight during erection or maintenance for positioning it with respect to a connection point with the wicket gate operating ring. The arrangement also provides a readily available permanent means for attaching an overhead crane hook to the wicket gate operating ring for stroking the gates during erection or maintenance. The arrangement also provides a means for operating the wicket gate operating ring when the operating ring servo-motors fail.

摘要： A calcining combustor for the suspension preheater of a rotary kiln cement manufacturing plant having a cooler for the clinker comprises an upright furnace vessel having an outwardly spiraling gas exhaust duct at its upper end leading to a preheater gas/meal separator and a mixing portion at its lower end; an inlet for hot combustion air from the cooler into the mixing portion; an inlet for cement meal from the preheater into the mixing portion downstream from the combustion air inlet to entrain the meal in the rising combustion air; and burners for injecting fuel into the air/meal stream downstream from the meal inlet to calcine the meal by heat released by burning of the fuel with the combustion air. The initial calcination temperature is a minimum because the combustion air atmosphere within the combustor is devoid of significant amounts of carbon dioxide and chlorine and alkali vapors typically present in kiln-off gases, and the endothermic calcination reaction absorbs heat energy to limit temperature rise within the combustor so that caking and formation of alkali and nitrogen oxide vapors is minimized. An alternative embodiment has an inlet for hot kiln-off gases into the furnace vessel at a point where substantial calcination has occurred so that both (a) calcining and (b) mixing of the calcined meal/air stream with the kiln-off gases to transfer heat energy thereto occur in a single vessel.

摘要： A thrust containment apparatus is disclosed for use with a pressurized rotary kiln gasifier. The thrust containment apparatus maintains stationary hoods mounted on both ends of the kiln shell in fixed positions by relieving the hoods of forces generated by high pressures within the kiln. The thrust containment device comprises braces mounted on the hoods on the sides remote from the kiln shell. Tie members, or tie rods, extending along the exterior of the kiln shell connect the braces. An expandable bellows is provided between one brace and its adjacent hood. As tie members deform through thermal and tensile expansion, the bellows accomodates the expansion while maintaining a gas-tight seal between the hood and the brace. Being of equal internal pressure as the kiln and having a diameter against the hood equal to the diameter of the seal connecting the hood to the kiln, the bellows relieves the hoods of all pressure forces and transmits these forces to the braces and tie rods thereby ensuring continuous stationary positioning of the hoods.

摘要翻译： 公开了一种用于加压回转窑气化器的止推装置。 推力容纳装置通过减轻由窑内的高压产生的力的罩，将固定的罩安装在窑壳的两端处于固定位置。 推力容纳装置包括安装在远离窑壳的侧面上的罩上的支架。 沿着窑壳外部延伸的领带构件或拉杆连接支架。 在一个支架和其相邻的罩之间提供可膨胀的波纹管。 随着连接件通过热膨胀和拉伸膨胀而变形，波纹管适应膨胀，同时保持罩和支架之间的气密密封。 由于与窑相同的内部压力并且具有与罩相反的直径等于将发动机罩连接到窑的密封件的直径，波纹管释放所有压力的罩，并将这些力传递到支架和拉杆，从而确保 罩的连续静止定位。
