1. A low focusing ratio, along with a thick insulation layer in the ash kiln, helps to maintain lower exhaust gas temperatures and ash exit temperatures, thereby reducing heat loss. 2. Prevents caking and lump formation inside the kiln, ensuring stable combustion within it. 3. The sizes of limestone and coke should be uniform. 4. The sealing performance of equipment such as kiln gas pipelines and kiln gas scrubbers should be good. 5. The calcium carbonate content in limestone should be as high as possible. 1# chen3jun
A reasonable distribution of particle sizes ensures good permeability within the kiln

1. With a low ash discharge rate, the insulation layer of the lime kiln must be thick enough to maintain a relatively low ash discharge temperature and minimize heat loss； 2. Prevents caking and lump formation inside the lime kiln, ensuring stable combustion within the kiln ； 3. The sizes of limestone and coke should be uniform ； 4. The sealing performance of equipment such as kiln gas pipelines and kiln gas scrubbing towers should be good ； 5. The content of CaCO3 in limestone should be as high as possible.
1. With a low tuning rate, the insulation layer of the lime kiln must be thick enough to maintain low exhaust gas and ash temperatures, thereby reducing heat loss. 2. Prevents caking and lump formation inside the lime kiln, ensuring stable combustion within the kiln. 3. The sizes of limestone and coke should be uniform. 4. The sealing performance of equipment such as kiln gas pipelines and kiln gas scrubbers should be good. 5. The content of CaCO3 in limestone should be high.
1. A low tuning rate; the lime kiln should have good thermal insulation to maintain low exhaust gas and ash temperatures, thereby reducing heat loss； 2. Prevents caking and lump formation inside the kiln, ensuring stable combustion ； 3. Ensure that the fed limestone and coke are of uniform size ； 4. Equipment such as kiln gas pipelines and scrubbers must have good airtightness ； 5. The content of the active ingredient in limestone (CaCO3) should be as high as possible
The conditions are: 1) A low heat loss rate; the insulation layer of the lime kiln must be thick enough to maintain low exhaust gas and ash temperatures, thereby reducing heat loss； 2) Prevents caking and lump formation inside the lime kiln, ensuring stable combustion within the kiln ； 3) The size of limestone and coke should be uniform ； 4) Equipment such as kiln gas pipelines and kiln gas scrubbing towers must have good sealing performance ； 5) The calcium carbonate content in limestone should be as high as possible
1. A low heat loss rate is required; the insulation layer of the lime kiln must be thick enough to maintain low exhaust gas and ash temperatures, thereby reducing heat loss； 2. Prevents caking and lump formation inside the lime kiln, ensuring stable combustion within the kiln ； 3. The size of limestone and coke should be uniform ； 4. The sealing performance of equipment such as kiln gas pipelines and kiln gas scrubbing towers should be good ； 5. The calcium carbonate content in limestone should be as high as possible.
1. Low ignition rate; thick insulation layer helps maintain a low furnace temperature and reduces heat loss. 2. Prevents clumping inside the lime kiln, ensuring stable combustion within the kiln. 3. Uniform size of limestone and coke. 4. Good sealing within the kiln. 5. High calcium carbide content in the limestone
Answer: 1. With a low burnout rate, the insulation layer of the lime kiln must be thick enough to maintain low exhaust gas and ash temperatures, thereby reducing heat loss； 2. Prevents caking and lump formation inside the lime kiln, ensuring stable combustion within it ； 3. The sizes of limestone and coke should be uniform ； 4. Equipment such as kiln gas pipelines and kiln gas scrubbing towers has good sealing performance ； 5. The content of CaCO3 in limestone should be as high as possible.
