Download the electronic version of the book: http://bbs.hcbbs.com/thread-13140-1-2.html short answer questions: 1. What are the conditions for maintaining a high decomposition rate of CaCO3?
1. The fuel ratio is appropriate to fully decompose CaCO3； 2. Sufficient decomposition time allows CaCO3 to decompose completely in the combustion zone ； 3. The combustion temperature cannot be too low, and there should be enough air volume to accelerate combustion in the kiln.

answer: (1) The fuel ratio is appropriate to fully decompose calcium carbonate. (2) Sufficient decomposition time allows calcium carbonate to decompose completely in the combustion zone. (3) The combustion temperature cannot be too low, and there should be enough air volume to accelerate combustion in the kiln.
There must be sufficient temperature, and the decomposed products must be discharged from the system in time.
answer: 1. The fuel ratio is appropriate to fully decompose CaCO3. 2. Sufficient decomposition time allows CaCO3 to decompose completely in the combustion zone. 3. The combustion temperature cannot be too low, and there should be enough air volume to accelerate combustion in the kiln.
The fuel ratio is appropriate so that CaCO3 is fully decomposed and the decomposition time is sufficient so that CaCO3 decomposes in the combustion zone and tends to complete. The combustion temperature cannot be too low and there should be enough air volume to accelerate combustion in the kiln.
.The fuel ratio is appropriate to fully decompose calcium carbonate.； 2. Sufficient decomposition time makes calcium carbonate decompose safely in the combustion zone ； 3. The combustion temperature cannot be too low, and there should be enough air volume to accelerate combustion in the kiln.
answer: a) The fuel ratio is appropriate to fully decompose calcium carbonate ； b) Sufficient decomposition time to allow complete decomposition of calcium carbonate in the combustion zone ； c) The combustion temperature cannot be too low, and there should be enough air volume to accelerate combustion in the kiln
1. The fuel ratio is appropriate to fully decompose CACO3. 2. Sufficient decomposition time allows CACO3 to decompose completely in the combustion area. 3. The combustion temperature cannot be too low, and there should be enough air volume to accelerate combustion in the kiln.
