Vertical Shaft Kiln for Petroleum Calcination / Shaft Kiln
Incinerator Price
Vertical Shaft Kiln Introduction:
Shaft Kiln originated in the sixty's of last century, is a kind of
lime vertical kiln, with two shafts, inner shaft and outer shaft.
The raw material is calcined between the inner and outer shaft
space. ZK CORP is the best Kiln suppliers in China.
Shaft Kiln Technological Process:
Shaft Kiln inner structure from top to bottom is pre-heating zone,
upper counter-follow calcining zone, lower parallel-follow
calcining zone, and cooling / discharge zone. Raw material is
screened firstly, then transferred to the top of the kiln by the
hoisting hopper, and then feed into the kiln body by the rotary
distributor evenly. Preheated raw material moves into the upper
calcining zone along the annular furnace charge space in where the
raw material is effective in decarburization. The almost-finished
lime in the upper calcining zone moves into the lower calcining
zone for effective homogeneous, then moves down to the cooling
zone, finally drops into the lime silo under the kiln by lime
pusher platform. The finished lime transferred to the storage by
the belt conveyer.
Vertical Shaft Kiln Structure:
The raw material to be calcined is charged at the top of the kiln.
It it then pre-heated by the combustion gases in the
counter-current before reaching the burning zone. In the burning
zone the material is calcined by means of fuel introduced together
with primary combustion air through radially arranged burner
lances. Cooling air is introduced at the discharge part of the kiln
to cool the product in a counter-current manner. The heated cooling
air travels upwards to the burning zone and is used again there as
the secondary combustion air.
From the top of the kiln he exhaust gas are directed to a dust
collecting system.
