Definitions

• the invention relates to a regenerator for regenerative type heat exchanger of the fluid pre-heaters.
• regenerator for heat exchanger consisting of horizontal courses which rest on lower adjacent horizontal courses, they being fastened against the relative movement by means of a stabilizing rib network on their top faces, as well as by a joint network at the level of each course incorporating at its bottom portion the rib course of the lower adjacent course.
• Each course also contains vertical cavities which are uniformly distributed on its surface and by an in-sequence overlapping the courses form continuous straight vertical channels, they being both separately positioned within the material mass, and on the rib and joint paths of the networks (RO Patent 113,869 and US Patent 5,924,744).
• This regenerator for heat exchanger has the disadvantage of not ensuring a communication through horizontal joint networks for a fourth of the vertical straight channels on the height of a three successive courses pack, but for a bigger pack only which can comprise even the whole height of the regenerator structure.
• the technical problem to be solved by the invention consists in providing a regenerator for heat exchanger that, by means of horizontal joint networks, ensures connecting all vertical straight channels by a maximum number of connections and with at least one connection to a pack having three sequential courses.
• the regenerator for heat exchanger accordingly to the invention solves this problem in that within any pack of three courses, lower, median and upper respectively, which are sequentially horizontally overlapped, several vertical channels in the lower course overlap other several vertical channels in the median course, and several vertical channels in the median course overlap several vertical channels in the upper course, so that between all the vertical channels in said three courses of the three courses pack, lower, median and upper respectively, there are several horizontal connections realized by a joint network of the lower course and by the joint networks of the median and upper courses, respectively.
• the vertical channels have a frustum of cone shape which is technologically motivated, having the large base at the lower side and, the slope of the frustum of cone portion in the range of 1 - 5%.
• the regenerator according to the invention consists in a pack A of courses 1 , 2 and 3 or more, lower, median and upper respectively, which are sequentially horizontally overlapped and adjacent packs B and C, lower and upper, respectively as against the pack A, on the attached figure being shown the upper course 4 of the adjacent pack B, as well as the lower course 5 of the adjacent pack C.
• joint courses 6, 7 and 8 are shown as well as rib networks 9, 10 and 11 intended to guiding and underside closing the channels of the upper course.
• the packs A, B and C are made up so that, according to the pack A, the vertical channels b overlap the vertical channels g, and the vertical channels h overlap the vertical channels m.
• the channels obtained by sequential overlapping the vertical channels a, i and n are horizontally united by the networks 6 and 8
• the channels obtained by sequential overlapping the vertical channels b, g and o are horizontally united by the networks 6 and 7
• the channels obtained by sequential overlapping the vertical channels c, h and m are horizontally united by the networks 7 and 8
• the channels obtained by sequential overlapping the vertical channels d, I and r are horizontally united by the network 8
• the channels obtained by sequential overlapping the vertical channels e, j and s are horizontally united by the network 6, and the channels obtained by sequential overlapping the vertical channels f, k and p are horizontally united by the network 7.
• the courses 4, 1 and 2, as well as the courses 2, 3 and 5 can form a similar pack as a rule of overlapping the pack A.
• overlapping the courses 4, 1, 2, 3 and 5 there are realized continuous vertical channels the longitudinal section of which is a sequence of pyramidal frustum having a periodical section variation of 10 - 30 %.
