    • Heat is reclaimed from a high temperature gasifier exhaust gas of between 250° C. and 20000C. A first duct receives the exhaust gas, and outputs it at a reduced temperature. A second duct receives a heat transfer fluid and outputs it at an elevated temperature. A heat transfer arrangement conducts heat extracted from the product gas to the heat transfer fluid (steam), thereby elevating the temperature of the heat transfer fluid. A heat pipe formed of sodium, potassium, rubidium, or lithium, has a first end for communicating with the high temperature exhaust gas and a second end for communicating with the heat transfer fluid. The heat pipe has an envelope formed of a selectable combination of stainless steel, Inconel, nickel, molybdenum, tungsten, niobium, carbon, carbon composite, and Hastelloy X, and a safety valve that ensures safe operation. An adiabatic zone is interposed between the first and second ducts.
    • 从250°C到200°C的高温气化炉排气回收热量。 第一管道接收废气,并在降低的温度下输出。 第二管道接收传热流体并在升高的温度下输出。 传热装置将从产物气体提取的热量传导到传热流体(蒸汽),从而提高传热流体的温度。 由钠,钾,铷或锂形成的热管具有与高温废气连通的第一端和用于与传热流体连通的第二端。 热管具有由不锈钢,铬镍铁合金,镍,钼,钨,铌,碳,碳复合材料和Hastelloy X的可选择组合形成的外壳,以及确保安全操作的安全阀。 在第一和第二管道之间插入绝热区域。
