PREMIXING BURNER AND METHOD OF OPERATING THE SAME
Document Type and Number:
Japanese Patent JPH07208710
Kind Code:
A
Abstract:

PURPOSE: To secure a stable mixed combustion and a reduced NOx emission with a limited degree of turbulence by supplying a fuel in a range of a Venturi section acting above the internal chamber of a premixing burner to let the stream of combustion air pass through the Venturi section.

CONSTITUTION: A fuel 31 is injected to a location to maximize the mixing speed of the stream 15 of combustion air with an inner chamber 14 of a premixing burner, namely, in the region of tangential air inlet slits 21 and 22. In the region, a Venturi mixer 32 is provided over the overall length of the premixing burner. The Venturi mixer 32 comprises a double path, namely, passages 33 and 34. The central Venturi body 35 simultaneously serves as fuel supply conduit. The Venturi body 35 is further provided with a nozzle 36 toward passages 33 and 34 on both sides. The passages 33 and 34 can develop a Venturi effect as other part bodies 37 and 38 adjoining them are formed in a Venturi likewise.
