Title:
EJECTION-TYPE COMBUSTION APPARATUS CAPABLE OF REDUCING PROTECTIVE-GUARD THERMAL STRESS
Document Type and Number:
WIPO Patent Application WO/2016/154984
Kind Code:
A1
Abstract:
Provided is an ejection-type combustion apparatus capable of reducing the thermal stress of a protective guard, comprising multiple layers of protective guards (10, 12, 14, 16) arranged along the vertical direction; each layer of protective guard (10, 12, 14, 16) is closed in the circumferential direction to form a flame chamber having top and bottom open ends. Of two adjacent layers of protective guards (10, 12, 14, 16) in the vertical direction, the radial width of the upper layer is greater than the radial width of the lower layer, such that an ejection area (18) in fluid communication with the flame chamber is formed between two adjacent protective guards (10, 12, 14, 16). The outer peripheral surface of at least one of the lower protective guards (10, 12, 14, 16) has a plurality of Venturi burners (20) distributed at intervals along its circumference. The upper part of each of the Venturi burners (20) extends into the ejection area (18) so that the flames formed by the Venturi burner (20) are covered by the immediately adjacent upper protective guard (10, 12, 14, 16) in the horizontal direction. Each of the Venturi burners (20) deflects radially inward with respect to the vertical direction.
