The design of cyclonic pre-heaters in suspension cement kilns
网页The total fuel consumption in modern kiln systems varies from 3000–3600 kJ/kg (dry process with multi-stage cyclonic pre-heaters and pre-calciners) to 3100–4200 kJ/kg (dry rotary kilns with cyclonic pre-heaters) and 3300–4500 kJ/kg (semi-dry/semi-wet processes). Long rotary kilns and shaft kilns (>5000 kJ/kg) now represent less than 1% of
