Problems solved by technology

[0003] The existing medium and small boilers were not designed with low NOx emissions and environmental protection requirements in mind at that time, only considering the energy saving effect, the design of the furnace area was too small, especially the installation position of the burner throat was too small, which was not conducive to the existing general low NOx burner installation; but the national environmental protection policy is imperative, and a large number of existing medium and small boilers must be transformed

Abstract

The invention discloses a gas burner with ultra-low NOx and CO emissions for medium and small boilers, comprising a brazier brick, a cylinder body assembly, a gas gun assembly and an ignition gun assembly. One end is provided with a bottom plate and an air adjusting port. One end of the gas gun assembly and the ignition gun assembly is installed on the bottom plate, and the other end extends toward the brazier brick. The gas gun assembly includes an outer gun and a center gun, and the other end of the center gun extends into the brazier brick. The other end of the outer gun extends to the outside of the brazier brick and is arranged along the circumference of the brazier brick, and the other end of any outer gun is provided with a plurality of outer gun nozzles for increasing the combustion flame area. The present invention can make good use of the existing furnace space to solve the problem of excessive flame concentration, thereby reducing NOx and CO emissions.

Description

technical field [0001] The invention belongs to the technical field of boiler combustion, in particular to an ultra-low NOx and CO emission gas burner for medium and small boilers and a method thereof. Background technique [0002] With the advancement of social science and technology, the enhancement of people's awareness of environmental protection and the increase of social environmental protection governance, my country's emission values ​​for air pollutants are becoming increasingly stringent. At present, most regions in my country are implementing low-NOx emission requirements for boilers. For existing boilers, low-nitrogen burner transformation is encouraged and rewarded to reduce NOx emissions to 50mg / Nm 3 Below, for new boilers, the NOx emission concentration requirement is specially formulated to be 30mg / Nm 3 The following environmental incentive standards. [0003] The existing medium and small boilers were not designed with low NOx emissions and environmental p...
