Abstract

The invention discloses a forced-draft flameless combustor, which mainly solves the problems of incomplete gas combustion and black smoke rising of the conventional combustor. The forced-draft flameless combustor comprises a combustor main body, wherein an air inlet is arranged at the bottom of the combustor main body, and a combustion seat is arranged at the top of the combustor main body; a gas inlet pipe is arranged in a vertical part of the combustor main body; a gas inlet is arranged at the bottom end of the gas inlet pipe, and an internal nozzle is arranged at the top end of the gas inlet pipe; the combustion seat is formed by movably overlapping a plurality of layers of funnel-shaped structures; and an adjustable clearance is reserved between every two layers of funnel-shaped structures. By unique design of the forced-draft flameless combustor, gas can be completely combusted, temperature is uniform during the arrangement of a plurality of combustors, a disk-shaped blue flame can be formed, a process is safe, carbon absorption is avoided, the problems of back fire and black smoke rising are solved, and the forced-draft flameless combustor is particularly applicable to a cracking furnace.

Description

technical field [0001] The invention relates to a burner, in particular to a forced draft flameless burner. Background technique [0002] Burners are widely used in various industrial furnaces. The existing burners are divided into two types: hole type and slit type. Emerging from through holes or crevices. The temperature of the above-mentioned burner is not uniform due to the flame emerging from the through hole or gap, and the combustion of the gas is not complete. The flame is orange, and black smoke and tempering will occur. In addition, due to its uneven temperature, carbon absorption will occur at points with higher temperatures during use, which will affect the performance of the equipment. For cracking furnaces, the flame temperature requirements are relatively high, and existing burners cannot meet the requirements of cracking furnaces well. Therefore, a burner with uniform temperature, complete combustion and safe process is needed. Contents of the invention ...
