Problems solved by technology

Its heating method traditionally adopts flame radiation heating or indirect heating (the heat of flame combustion is transferred to the heated medium through the heat transfer medium), which has the characteristics of high heat emission, low thermal efficiency and high energy consumption.
These problems are exacerbated for high temperature manufacturing processes such as glass melting

[0136] figure 2 A burner according to a second exemplary embodiment of the present invention is shown. In the second embodiment, a plurality of through passages 11 are formed in the nozzle 1, and the plurality of through passages 11 include inner passages and outer passages, wherein the outer outlets 1121 of the outer passages are located at the ends of the inner passages in the radial direction of the nozzle. outside of each internal outlet 1111. The sum of the cross-sectional areas of the outlets 1111 and 1121 of the plurality of through passages is greater than the cross-sectional area of ​​the mixing passage 23 . exist figure 2 It is shown that each through channel 11 comprises a first portion extending from its inlet in a direction away from the axis of the nozzle and a second portion extending from the first portion in a direction parallel to the axis of the nozzle to the outlet of the through channel. two parts. With this structure, the first part of the plurality...

Abstract

The invention relates to a burner, in which at least one first passage (21) and at least one second passage (31) are formed, the at least one first passage (21) and the at least one second passage (31) are arranged such that a first fluid from an outlet (23) of the at least one first passage (21) and a second fluid from an outlet (33) of the at least one second passage (31) are mixed with each other, and the at least one first passage (21) is configured such that the first fluid generates a swirl in a first swirl direction, and / or the at least one second passage (31) is configured to enable the second fluid to generate rotational flow in the second rotational flow direction. The combustor has the advantages that flames are more stable, the explosion risk is avoided, the combustion performance is improved when hydrogen serves as fuel to be combusted, backfire of the combustor is avoided, ablation of the combustor is reduced, blockage of a nozzle by a heated medium is avoided, and the state of the combustor is monitored.

Description

technical field [0001] The invention relates to a burner, an assembly comprising the burner, a module comprising the burner and a heating device provided with the burner. Background technique [0002] CO 2 Emissions have become a common concern of the international community. This is one of the most important topics in today's society. Everyone is trying to reduce CO 2 emissions solutions. One of the main directions is to reduce CO by reducing energy consumption and improving energy utilization 2 emissions. [0003] A burner is a device that converts oxidant and fuel into heat energy through the chemical reaction of combustion. The heating device (such as a furnace) heats the heated medium in it by setting a burner. Its heating method traditionally adopts flame radiation heating or indirect heating (the heat of flame combustion is transferred to the heated medium through the heat transfer medium), which has the characteristics of high heat emission, low thermal effici...
