1. Sufficient fuel; the coke ratio must not be too low. 2. Adequate decomposition time. 3. The combustion temperature must not be too low; there must be sufficient air pressure and air volume
The main requirements are: (1) Sufficient production; the coke ratio must not be too low； (2) Sufficient decomposition time ； (3) The combustion temperature must not be too low to ensure sufficient air pressure and air intake.
1. Sufficient fuel; the coke ratio must not be too low； 2. Sufficient decomposition time ； 3. The combustion temperature must not be too low; sufficient air pressure and air volume must be ensured.
Answer: The main requirements are: ① sufficient fuel; the coke ratio must not be too low; ② adequate decomposition time； ③The combustion temperature must not be too low; sufficient air pressure and air volume must be ensured.
The main requirements are: sufficient fuel, and the coke ratio must not be too low； Enough time for decomposition ； The combustion temperature must not be too low; sufficient air pressure and airflow must be maintained
Mainly, the following must be ensured: 1. Sufficient fuel; the coke ratio must not be too low. 2. Sufficient decomposition time. 3. The combustion temperature must not be too low; sufficient air pressure and air volume must be ensured.
Answer: 1) A low fusing 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) Prevent ash and lumps from forming inside the lime kiln, ensuring balanced 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 as high as possible.
