Embodiment approach

[0045] The present invention will be described below with reference to the accompanying drawings. However, the present invention can be implemented in many different forms, and therefore is not limited to the embodiments described here. In addition, in order to clearly describe the present invention, parts irrelevant to the description in the drawings are omitted, and similar reference numerals are assigned to similar parts throughout the specification.

[0046] Throughout the specification, when it is mentioned that a certain part is connected (connected, contacted, combined) with other parts, this includes not only the case of "direct connection" but also the case of "indirect connection" with other parts interposed therebetween. And, unless there is a special record to the contrary, when it is mentioned that a certain part "includes" a certain constituent element, it means that other constituent elements are further included, and other constituent elements are not excluded....

Abstract

One embodiment of the present invention provides a combustor having excellent performance with respect to high-efficiency and low-emission combustion since a flame is formed by optimizing a divided-flame technology, an air-staged technology, a partially-premixed fuel technology, and a fuel gas recirculation technology. An ultra-low emission combustor according to one embodiment of the present invention comprises: a flame generation part in which mixed fuel and air is combusted so as to generate a first flame; and a multi-stage air supply part into which a portion of the flame generation part is inserted and supplying combustion gas or air to a region of a second flame inside a combustion chamber.

Description

technical field [0001] The present invention relates to an ultra-low emission burner, and in more detail, relates to a flame formation by optimizing split flame technology, air staging technology, partial fuel premixing technology and combustion gas recirculation technology, therefore, high efficiency Excellent low emission combustion performance. Background technique [0002] Due to energy depletion and environmental problems, high-efficiency, low-emission combustion of combustion systems is now essential, and in order to achieve this, research for improving the performance of the burner and combustion control for improving the operation method are actively carried out. [0003] Existing representative low-emission combustion technologies include dye classification technology, air classification technology, combustion gas recirculation technology, internal combustion gas recirculation technology, re-combustion technology, OFA technology, etc. However, this combustion techn...
