Abstract
The ejector system of annular lime kiln was modified for energy saving and pollution reduction. Under the principle of high air pressure and speed, the driving air flow and movement system was improved to achieve high ejector pressure and strong siphon effect. The technical transformation has broken the traditional cognition that two driving fans must be applied at full load in the industry. A single fan can meet the full production. The power and fuel consumption potentially reduced, and the output of quicklime increased. After renovation works, about 125 m3/h of coke oven gas and 250 m3/h of converter gases were saved. The temperature of the combustion chamber increased for 20 °C after modification.
