During operation, introduced at blast furnace gas and coke-stove gas, the manual firing hole on the left of burner hearth and lighted a fire by burner,
And burning generates hot gas in the presence of combustion-aid air pipe, at the same time, blast furnace gas is passed through with the air in combustion-aid air pipe I
Enter burning mixing chamber after spiral board, make hot gas burning more abundant, and oxygen content and carbon monoxide in flue gas can be reduced contain
Amount, hot gas is able to detect that top temperature, outlet temperature, furnace top pressure, outlet pressure in burner hearth, also can detect blast furnace coal
Gas, combustion air flow, exhaust gas flow, and the with the naked eye combustion case in stove directly from peep hole can be used, then hot gas
Enter taper flue gas mixing-chamber through taper exhanst gas outlet, the waste gas of exhaust gas entrance is tangentially from taper exhanst gas outlet lateral wall
Screw thread is mixed into taper flue gas mixing-chamber with hot gas, it is ensured that the stabilization of outlet wind-warm syndrome, generation meets the flue gas of technological requirement,
Coal mill system drying hot blast consumption and system atmosphere inerting most are delivered to through exhanst gas outlet and hot blast introduction pipe afterwards, is overcome existing
The problem of there is easy deflagration phenomenon and unstable wind-warm syndrome because structure design is unreasonable in flue gas drying stove.
The utility model reasonable in design is reliable, is effectively guaranteed the stabilization of outlet wind-warm syndrome, and reduces flue gas
In oxygen content and carbon monoxide content, prevent to cause the generation of deflagration phenomenon during drying coal dust, do not leaked with sealing
Gas, furnace cavity it is big and can detection temperature, pressure and furnace flame fired state advantage, it is adaptable to metallurgy, electric power, chemical industry,
The coal mill system drying hot blast of machinery, building materials and industrial state's stove industry and system atmosphere inerting.
