专利汇可以提供Heat exchanger installation for a closed gas circulatory system, such as a thermal power plant, for example专利检索，专利查询，专利分析的服务。并且A closed helium gas circulatory system includes a compressor, nuclear reactor, turbine, and heat exchanger installation serving as recuperator and precooler, the recuperative heat exchanger and the precooling heat exchanger of the installation both having tubes, the tubes of one of the heat exchangers being disposed concentrically or coaxially to those of the other heat exchanger.，下面是Heat exchanger installation for a closed gas circulatory system, such as a thermal power plant, for example专利的具体信息内容。
1. Heat exchanger installation for assembly in a closed gas circulatory system which includes a heat consumer and a heat source located upstream of said heat consumer in flow direction of gas in said circulatory system, comprising a recuperative heat exchanger, a precooling heat exchanger, and means for conducting gas, that has been cooled in the heat consumer, through said recuperative heat exchanger for preheating the gas to said precooling heat exchanger for removing heat from the circulatory system, said precooling heat exchanger for removing heat from the circulatory system being connected to the heat source through a compressor and through said recuperative heat exchanger for preheating the gas, one of said heat exchangers having tubes disposed around a centrally located space, and the other of said heat exchangers having tubes projecting into said centrally located space, supply and discharge lines for heat exchanging working medium traversing the tubes of said heat exchangers being located at one end of each of said heat exchangers, a supply inlet for heated waste gas delivered from the heat source and a gas discharge outlet both being located at the other ends, respectively, of said recuperative heat exchanger for preheating the gas and of said precooling heat exchanger for removing heat from the circulatory system, and flowthrough opening means for the gas located between said centrally located space and the space surrounding the same at said other ends of said heat exchangers at which said waste gas supply inlet and said gas discharge outlet are located.
2. Heat exchanger installation according to claim 1 wherein the tubes of said precooling heat exchanger for removing heat from the circulatory system project into said centrally located space, and the tubes of said recuperative heat exchanger for preheating the gas are disposed in a space surrounding said centrally located spaced, said tubes of said precooling heat exchanger being shorter than those of said recuperative heat exchanger so as to form a free region surrounded by the tubes of said recuperative heat exchanger, and including distributor tubes for waste gas flowing out of the heat consumer, said distributor tubes being located in said free region.
3. Heat exchanger installation according to claim 1 wherein at least the tubes of the heat exchanger projecting into said centrally located space are suspended at only one end thereof within the installation.
4. Heat exchanger installation according to claim 3 including a closure plug located at an upper end of said centrally located space and holding said last-mentioned tubes within said centrally located space.
5. Heat exchanger installation according to claim 4 including a substantially cylindrical vessel wherein said heat exchangers are received, said closure plug, from which the tubes of said precooling heat exchanger are suspended in the centrally located space, projecting into said substantially cylindrical vessel, and including an insert fitted in said cylindrical vessel and carrying a tube plate, the tubes of said recuperative heat exchanger surrounding said centrally located space being secured to said tube plate.
