| Abstract: |
| The energy-utilization characteristics of shuttle kiln has been explained, its heat-balance model built, and its technical reformation scheme of energy-saving proved. Researches show that the consumption of liquefied petroleum gas per furnace without flue gas waste heat recovery reaches 2301Nm3, the thermal efficiency 14.7% and the energy utilization ratio 56.3%. The increase of heat efficiency from high-efficiency waste heat recovery of flue gas caused by the fast-handover-type big-specific-surface-area ceramic regenerator is 17.1% and the relative energy saving ratio 116.3%. Low-oxygen dynamic combustion and high-temperature swirling combustion during the temperature rising period from 300 centigrade to 980 centigrade and from 980 centigrade to 1240 centigrade based on the principle of the high-efficiency waste heat recovery of flue gas and the intensive convection heat transfer between the flue gas and the production surface is theoretically the feasible reformation scheme of energy-saving. |
