Title:

REGENERATIVE TYPE BURNER AND STORAGE TYPE HEAT EXCHANGING SYSTEM AVAILABLE THEREFOR

Document Type and Number:

WIPO Patent Application WO/1995/015462

Kind Code:

A1

Abstract:

The invention relates to a storage type heat exchanging system for performing heat exchange by alternately passing a combustion exhaust gas, which is a high temperature fluid, and an air for combustion, which is a low temperature fluid, through a stationary heat reservoir, and a regenerative type burner for effecting combustion by the use of a preheated air of high temperature provided by the system. The storage type heat exchanging system comprises a porous heat reservoir (1) which is divided into three or more compartments in a circumferential direction, entrance exit means (6) which is in the form of a dual pipe and is divided into a feed chamber (6a) and an exhaust chamber (6b), and switching means (3) for providing cutoff between the heat reservoir (1) and the entrance/exit means (6) and selectively providing communication between the heat reservoir (1) and the entrance/exit means (6) by means of a feed communication hole (5) and an exhaust communication hole (4) which are provided in such a positional relationship that the both holes are not existent in any one of the compartments (9, 10, 11) of the heat reservoir (1) at the same time and form the vacant compartment (10), through which any fluid does not flow, at at least a location between the compartment (11), through which an exhaust gas flows, and a compartment (12), through which air flows. Further, provided in the storage type heat exchanging system is a fuel nozzle (31) extending centrally therethrough to continuously jet a fuel, and an air of high temperature for combustion is caused to be jetted from the heat reservoir, thereby constituting a regenerative type burner. Also, the heat exchanging system in which a flow direction is not changed can be provided by providing the entrance/exit means (6, 6) and switching means (3, 3) before and behind the heat reservoir (1), without providing the fuel nozzle (31).
