Background technique
After sintering process itself needs large quantity of air, ignition furnace to install in sintering ignition furnace, in ignition furnace of sintering machine
A semiclosed region is formed in length, the air capacity that sintering ignition blower provides generally only considers sky required for gas-fired
Tolerance, and this air capacity that sintering ignition blower provides much is unable to satisfy the needs of sintering process, it need to also be by surrounding gap
Supplement air.Existing sintering ignition furnace is generally made of lighting section and soaking zone two parts, between lighting section and soaking zone by
The fiery beam of one piece of gear is isolated, and fiery beam and sintering charge level a certain distance are kept off, and air required for soaking zone itself is except a part
Outside by heat preservation segment trailer and trolley edge supplement, there are also quite a few be by gear fire beam between lighting section and soaking zone with
Gap between charge level supplements, this high-temperature flue gas for resulting in lighting section is lost to soaking zone, due to heat loss, so can disappear
Consume more coal gas.Common practice is, supplements portion of air in soaking zone when operation, gas consumption will be declined.
However, keeping off fiery beam cannot be designed too close apart from charge level, distance is too close, and keeping off fiery beam can then influence due to encountering the charge level of fluctuation
Production, by test, due to keeping off, there are gaps between fiery beam and charge level, still inevitably have hot fume to flow to from lighting section and protect
Temperature section, this also result in can not be inevitable between lighting section and soaking zone there are the convection current of hot fume, to cause more coals
Gas increases production cost by unnecessary consumption.
