Specific embodiment
The utility model is described below with reference to the accompanying drawings of the specification.
As shown in figures 1-4, a kind of roller bottom furnace Two-cuff Technique combustion system, including furnace body 1 and reversal valve, wherein in the furnace
The top and lower part of 1 two sides wall 2 of body are equipped with burner 3, are respectively equipped with gas port 31 and air scoop 32 on the burner 3,
Burner 3 all in entire furnace body 1 is divided into several segments, the burner 3 in every section is a sub-control combustion zone；
In the same sub-control combustion zone, the gas port 31 on the same side wall 2 is connected with by combustion gas branch pipe 41
Combustion gas supervisor 51, in two sides, the end of combustion gas supervisor 51 is respectively connected with a combustion gas reversal valve 61, two combustion gas reversal valves 61 it
Between pass through gas header pipe 71 and the connection of flue gas general pipeline 73；
Air scoop 32 on the same side wall 2 is connected with air supervisor 52 by air branch pipe 42, in two sides air
The end of supervisor 52 is respectively connected with an air reversing valve 62, passes through air header 72 and cigarette between two air reversing valves 62
