蓄热式热交换器是由罗伯特·斯特林博士于1816年首次提出并建造的，与蓄热式热气机相结合。从那时起，它的使用主要局限于炉膛空气预热器。然而，随着燃气轮机的出现，出现了对高热比和低压力损失的紧凑型换热器的需求。这是必要的，倾向于使用小水力直径的气体通道。在回热器中，对气体通道尺寸的限制是由于在位置上产生和支撑细长通道的困难，这些通道必须执行将热量从一种气体传递到另一种气体和将两种气体保持在不同压力下的双重功能。回热器中的小气体通道也容易被燃气轮机机组热气体的沉积物堵塞。最近人们对蓄热式热交换器重新产生了兴趣，这是因为它表现出了满足这些反对意见的前景。要求……
The regenerative heat exchanger was first proposed and constructed by Dr. Robert Stirling in 1816, in connexion with a regenerative hot-air engine. Since then its use has been mainly confined to furnace air preheaters. With the advent of the gas turbine, however, the need has arisen for a compact heat exchanger of high thermal ratio and low pressure loss. This, of “necessity, tends to the use of gas passages of small hydraulic diameter. In the recuperator, a limit to the size of the gas passages is imposed by the difficulties of producing and supporting in position long thin passages which must perform the dual function of transferring heat from one gas to another and of keeping separate the two gases at different pressures. Small gas passages in a recuperator also tend to become blocked with the deposits from the hot gases of a gas-turbine unit.The renewed interest recently taken in the regenerative heat exchanger is due to the promise which it shows of meeting these objections. The requirement that the ...
