    • A system and method for rapid cooling a hot isostatic press including a pressure container. The pressure container has an internal load space and includes insulation disposed at least partially around the load space, heating elements disposed inside the insulation, and a load disposed on a load bearing plate. Fluid is directed into the load space of a pressure container using at least one nozzle to form a rotational flow. The fluid from the at least one nozzle is mixed as it passes through the rotational flow near the insulation with fluid near the load. The fluid from the at least one nozzle has a lower temperature than the fluid in the load space and/or the load.

    • An apparatus for cooling a hot product gas, the latter is passed through a tubular zone. The product gas contains particles which, on entering the tubular zone, are tacky, but lose their tackiness through cooling in said zone. Within said zone a cooling gas flow forms a gas wall, which prevents contact between the product gas or the tacky particles contained therein, and one of the fixed walls in the tubular zone. Thus within an outlet connection (2) forming the tubular zone is provided an anular insert (3), which forms a gap (4) with the outlet connection. A cooling gas is blown into this gap counter to the flow direction of the product gas. At the end of the insert, this cooling gas is deflected by the product gas and flows within the insert in the same direction as the product gas and protects the inner wall of the insert from the latter. This product gas is cooled to such an extent by the action of the cooling gas that the particles in the product gas have lost their tackiness at the outlet-side end of the insert.
    • 用于冷却热产物气体的装置,其通过管状区域。 产物气体包含在进入管状区域时发粘的颗粒,但是通过在所述区域中的冷却而失去其粘性。 在所述区域内,冷却气体流形成气体壁,其防止产物气体或其中所含的粘性颗粒与管状区域中的一个固定壁之间的接触。 因此,在形成管状区域的出口连接件(2)内设置有与出口连接件形成间隙(4)的孔口插入件(3)。 冷却气体与产品气体的流动方向相反地吹入该间隙。 在插入件的末端,该冷却气体被产品气体偏转,并沿与产品气体相同的方向在插入件内流动,并保护插入件的内壁免于产生气体。 该产品气体通过冷却气体的作用被冷却到产品气体中的颗粒在插入件的出口侧端部失去粘性。

    • This invention is directed to the contact interchange of thermal and kinetic energy between adjacent compressible fluid streams across a virtual heat transfer surface at substantially different velocities in parallel flow. The invention may find especial application as a regenerative heat exchanger in gas turbine power plants, or as the low-velocity contact-type air pre-heater of a steam generator or furnace. Hot low-pressure exhaust fluids and cool compressed intake fluids enter the receiver-side section of an elongate heat exchanger. Intake-fluid stream pressure energy is converted to kinetic energy within nozzle passageways of the receiver-side section. The cold high-velocity intake-fluid stream is rapidly heated in the velocity-accelerated contact interchange process by the hot low-velocity exhaust-fluid stream within the mixing section. Following the contact interchange process, the intakefluid and exhaust-fluid streams are separated from each other by flow-dividing members and discharged from the separator-side section. Within the preheated intake-fluid stream, normal shock in supersonic flow across the inlet of the intake-fluid discharge passage is averted by the effects of variable control over characteristic length and exhaust-fluid outlet flow control.

    • Flue gas is a by-product of many energy and industrial plants and is typically emitted through a chimney stack. If the flue gas temperature in the chimney stack drops below the flue gas dew point, condensation of water vapor and acid gases ensues. These gases are very corrosive for chimney stacks designed to operate in a dry condition. The Flue Gas Reheat System of the present invention continuously and proactively manages flue gas chimney stack temperatures above the dew point in order to optimize emission control and effectuate energy efficiency improvements in industrial plants. Waste heat is harvested from the exterior surfaces of existing steam and pollution control equipment through conduction, convection and radiation. This heat is transferred to a working fluid. The working fluid is then directly mixed with the flue gas prior to the flue gas entering the chimney stack to raise the temperature of (or re-heat) the flue gas above its dew point to maintain a dry chimney stack condition. The use of residual or waste heat from throughout the plant and the minimal equipment required to harvest the waste heat reduces the operating cost and improves the overall reliability of the system. This method is useful in many industries, including electric power generation plants and other energy intensive process industries that seek emission control and various boiler and fuel energy efficiency improvements, many of which improvements result in a reduction in normal chimney stack temperature.
    • 烟气是许多能源和工业厂房的副产品,通常通过烟囱堆放出来。 如果烟囱中的烟气温度低于烟气露点,则会导致水蒸汽与酸性气体的冷凝。 这些气体对于设计​​为在干燥条件下工作的烟囱堆叠是非常腐蚀性的。 本发明的烟气再热系统连续主动地管理高于露点的烟道烟囱烟囱温度,以便优化排放控制并实现工业设备的能源效率改进。 废热通过传导,对流和辐射从现有蒸汽和污染控制设备的外表面收获。 这种热量被传递到工作流体。 然后在烟道气进入烟囱之前,将工作流体与烟道气直接混合,以将烟道气(或再加热)升高到其露点以上以保持干烟囱堆叠状态。 使用来自整个工厂的残余或余热以及收集废热所需的最少设备降低了运行成本并提高了系统的整体可靠性。 这种方法在许多行业中是有用的,其中包括寻求排放控制和各种锅炉和燃料能源效率改进的发电厂和其他能源密集型过程工业,其中许多改进导致正常烟囱堆温度的降低。
