Intensified combustion device in a furnace

Abstract

Disclosed is an inner furnace reinforcing burner. The burner comprises a secondary combustion chamber wall, a secondary combustion chamber at the inner side of the secondary combustion chamber wall, and an oxygen supply blower fan at the outer side of the secondary combustion chamber wall. The secondary combustion chamber comprises at least two cylindrical strong combustion chambers. The bottom parts of the strong combustion chambers are communicated with a primary combustion chamber through a fire outlet. The top part of the strong combustion chamber is communicated with an exhaust heat boiler. The secondary combustion wall is provided with a turbulent flow oxygen feeding channel that comprises an annular oxygen conveying channel and a tangential oxygen spraying channel. The air outlet of the tangential oxygen spraying channel is communicated with the oxygen supply blower fan at the outer side of the secondary combustion chamber wall through the annular oxygen conveying channel. The burner allows a plurality of cylindrical strong combustion chambers to replace the traditional strong combustion chamber with a rectangular cross section, utilizes the tangential oxygen spraying channel to supply oxygen for the strong combustion chamber, overcomes the defects that the secondary combustion chamber of a mechanical furnace row type household garbage incinerator fails to enables full combustion, is likely to generate black smoke, achieves the goal of treatment form the fountainhead and protects the environment.

Description

technical field [0001] The invention relates to an intensified combustion device used in domestic waste incinerators. Background technique [0002] The second combustion chamber in the mechanical grate type domestic waste incinerator (including imported technology) currently used in the society (see the Figure 4 ), which is a vertical space with a rectangular section (that is, the cross-sectional shape of the second combustion chamber is a rectangle), and in order to supplement the oxygen in the second combustion chamber, the vertical space with a rectangular section is installed on the front and rear walls along the width direction of the furnace Multiple jets for oxygenation. After years of practice, it has been proved that the high-temperature flue gas in the secondary combustion chamber of this structure cannot be fully mixed with the supplementary oxygen, and there is a low-temperature dead angle, which cannot completely burn the combustibles and achieve full combustio...
