Title:
FLOW PASSAGE CHANGE-OVER APPARATUS, REGENERATIVE ALTERNATE COMBUSTION BURNER SYSTEM AND REGENERATIVE HEAT EXCHANGER SYSTEM
Document Type and Number:
WIPO Patent Application WO1994002784
Kind Code:
A1
Abstract:
This invention relates to a flow passage change-over apparatus of a simple construction capable of carrying out a change-over operation at a high speed without causing the leakage of a gas between two systems of flow passages, for example, two flow passages through which two kinds of gases of different temperatures are introduced. A casing of the apparatus is divided by partitions (5, 6, 7) into a total of four chambers, i.e. two fixed chambers (2a, 2b) connected to two systems of flow passages in which the directions of flow of fluids are fixed, and two change-over chambers (4c, 4d) connected to two systems of flow passages in which the directions of flow of fluids can be changed over alternately. The two fixed chambers (2a, 2b) are allowed to communicate with different change-over chambers (4c, 4d) alternately by the change-over means (3). A regenerative alternate combustion burner system is formed by using this flow passage change-over apparatus, or a regenerative heat exchanger system is formed by installing the flow passage change-over apparatuses changing the direction of a flow of a fluid by the upstream side flow passage change-over apparatus and changing after the passage of the fluid through the heat accumulator the direction of the flow of the fluid to the original direction by the downstream side flow passage change-over apparatus.
