Abstract

The multiple fire hole flame-free ceramic burners is used in flameless combustion industrial furnace and kiln, especially hot blast stove for iron making blast furnace. The multiple fire hole flame-free ceramic burner has two outer ring gas channels. After air through the air inlet and gas through the gas inlet enter the air preheating ring channel and the gas ring channel, gas and air are preheated in between two ring channels before jetting to the mixer for mixing and jetting through the combustion nozzle to combust. The gas ring channel has guide bricks for homogeneous distribution of gas. The present invention has unique structure, small size and great power, and is suitable for various kinds of hot blast stove with heat accumulator.

Description

technical field

[0001] The invention belongs to the technical field of ceramic burners for industrial furnaces, in particular to the technical field of ceramic burners for flameless combustion of top-fired hot blast stoves in ironmaking blast furnaces. Background technique

[0002] The top-combustion hot blast stove is a new type of furnace structure. Since the 1960s, metallurgists in various countries have begun to pay attention to it and then carried out extensive research; at present, the top-fired hot blast stove has been considered as a hot blast Furnace technology development direction. Since the top-combustion hot blast stove does not have a special combustion chamber for gas combustion, its top space is much smaller than the tall combustion chamber of the external combustion hot blast stove and the internal combustion hot blast stove. In such a small space, In order to realize the complete combustion of a huge amount of gas, a flameless combustion device with high c...
