Title:
NOVEL HEATING FURNACE HAVING MULTI-HEARTH STRUCTURE, AND DESIGN METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/192307
Kind Code:
A1
Abstract:
Provided are a novel heating furnace having a multi-hearth structure, and method and use thereof. The heating furnace comprises a feed channel (1), a combustor (2), a furnace body and a collection outlet channel (7). The number of the combustor (2) is one. The furnace body comprises at least two hearths (3, 4) therein. An inlet of each hearth (3, 4) comprises a heat-insulated switch-board (10, 11) capable of being opened and closed. Remote differential pressure gauges (8, 0) are respectively provided between an inlet and an outlet of each hearth (3, 4). A feed space (13) is formed between the combustor (2) and the hearths (3, 4). The feed channel (1) communicates with the feed space (13). Each hearth (3, 4) comprises an outlet channel (5, 6). A heat-insulating filler is filled between the adjacent hearths (3, 4). Without changing a furnace tube configuration, a furnace tube material and the number of the combustor, when a hearth has a problem, a heating operation can be timely switched to another hearth without suspending normal operation for a heating furnace overhaul, thereby extending an operation suspension interval of a device required by the heating furnace overhaul, improving operation stability of the device, and eliminating a need of installing a spare furnace and accordingly reducing the cost.
