Short-answer question 1. What are the main heat losses in gray kilns? Please hide the replies; no scoring will be given in principle if they are not hidden. Specific hiding method: http://bbs.hcbbs.com/viewthread.php?tid=492556&highlight=%D2%FE%B2%D8
1. Heat carried away by the kiln gases 2. Losses due to ash discharge 3. Heat required to evaporate the moisture in the diluted material 4. Thermal losses in the lime kiln equipment 5. Incomplete combustion of limestone
1. Heat carried away by kiln gas 2. Heat carried away by ash discharge 3. Heat required to evaporate the water in the diluted material 4. Heat emitted from the outer surface of the ash kiln 5. Incomplete combustion of limestone
Uneven distribution of material, pressure loss in pipes, inefficient circulation of material, fly ash loss
1 Wall heat dissipation 2 Wall air leakage 3 Flue gas emission
Heat carried away by kiln gas and ash discharge, heat required to evaporate the water in the diluted material, heat emitted from the outer surface of the ash kiln, incomplete combustion of limestone
1. Heat carried away by the kiln gases 2. Heat carried away by the ash discharged 3. Heat required to evaporate the moisture in the diluted material 4. Heat emitted from the outer surface of the ash kiln 5. Incomplete combustion of limestone
Furnace gas carries away heat; ash discharge carries away heat; heat required to evaporate the water in the dilute material; heat emitted from the outer surface of the ash kiln; incomplete combustion of limestone.

What are the main heat losses in gray kilns? Answer: 1. Heat carried away by kiln gas; 2. Heat carried away by the ash being discharged; 3. Heat required to evaporate the moisture in the dilute material; 4. Heat emitted from the outer surface of the ash kiln; 5. Incomplete combustion of limestone. 1# chen3jun
