Background technology
Annular lime kiln is little because of floor space, and finished product activity of lime is high, and the porosity is high, the raw low advantage of burning rate and wide
The general lime production enterprise being applied to metallurgy, chemical industry and building materials field.The traditional fuel of annular lime kiln is coal gas, such as coke-oven coal
Gas, coal gas of converter or blast furnace coke oven mixed gas etc..In recent years, dive with industrial deep-cutting and energy saving and cost lowering requires, and permitted
Multiple enterprises, because the restriction of area surroundings, do not have enough coal gas for lime production.Therefore, lime production producer is for annular
Sleeve kiln is persistently raised as the attention rate of fuel using coal dust, domestic has also gradually started to annular lime kiln coal combustion technology
Theoretical Proof and practical exploration.
Annular lime kiln fire coal mainly problem is encountered that the indoor slagging scorification of burning aborning.Coal dust sprays into burning through burner
Burn rapidly after interior, the high temperature that burning produces makes the ash in coal dust be softened or melted, and a part of ash is attached to burning
On the resistance to material in room, cooling and solidifying forms slagging scorification, so builds up from level to level, and the indoor slagging scorification amount of burning gets more and more.
Need to stop burner combustion by manually or mechanically mode scarfing cinder, wait burning indoor temperature to reduce, the knot of softening
After slag becomes fragile, can clear up.This manner of cleaning up affects the continuous production operation in limekiln, and the resistance to material life-span to combustor
There is harmful effect.And if not clearing up combustor for a long time, on the one hand, combustor flowing resistance increases, flow field is destroyed, and affects Calx
The calcine technology of sleeve kiln；On the other hand, flame flows in kiln after burning part coal ash and melting, and slag easily forms on resistance to material and hangs
Wall and lead to limestone to lump, affects Calx quality, once causing viscous kiln, will also have to stop kiln process caking.
