Abstract: Under the condition of low calorific value converter gas as fuel, the limestone suitable for low calorific value calcination process is selected after high coke mixed gas replaced by converter gas in the double D lime kiln of Nangang. In view of the adverse effects of low calorific value gas, a series of equipment and process improvements are carried out, which effectively overcome the disadvantages of low calorific value gas, stabilize kiln production and increase the production capacity of double D lime kiln.

Key words: Double D lime kiln, Low calorific value gas, Calcination process, Capacity enhancement
