Limestone was calcined in a rotary kiln fired with natural gas. The kiln was operated at steady state, producing 280 tons of dead-burned (calcined at a higher temperature and for a longer time than usual, driving off all carbon dioxide) lime per day. The stone fed to the kiln analysed 96% CaCO3, 2% SiO2, 1% Fe₂O3, and 1% H₂O. Calculate: a. The feed rate of limestone b. The chemical analysis of the lime made

Question
Limestone was calcined in a rotary kiln fired with natural gas. The kiln was operated
at steady state, producing 280 tons of dead-burned (calcined at a higher
temperature and for a longer time than usual, driving off all carbon dioxide) lime
per day. The stone fed to the kiln analysed 96% CaCO3, 2% SiO2, 1% Fe₂O3, and 1%
H₂O. Calculate:
a. The feed rate of limestone
b. The chemical analysis of the lime made
