QC290/370-24 (8)-1.6/350(0.35/190) Cement kiln AQC Waste Heat Boiler Design Instruction  PAGE 6 QC290/370-24 (8)-1.6/350(0.35/190) Cement kiln AQC Waste Heat Boiler Design Instruction R095-SM-1 Prepared by: Reviewed by: Verified by: Approved by: July, 2010 Changsha Boiler Plant Co., Ltd P.R.China Content I Preface II Boiler parameters III Basic size IV Design introduction V Structure introduction I Preface According to the parameters requirement of cement kiln AQC tail gas, on the basis of our mature structure of waste heat boiler serial product and domestic and overseas latest cement kiln waste heat boiler, we developed the QC290/370-24(8)- 1.6/350(0.35/190) waste heat boiler. It is a kind of waste heat boiler for pure low-temperature cement kiln waste heat power generation which fulfills the AQC tail gas waste heat recovery of 5000~6000t/d clinker production of cement industry. This boiler can not only make effective use of the waste heat, but facilitate the operation of the following process, reducing the product cost and energy product, strengthening the company’s marketing competitiveness. Meanwhile, it also fit the national energy policy and will be an irresistible trend in the future. II Boiler parameters i) Inlet exhaust gas parameters (1) Inlet exhaust gas quantity 290000Nm3/h (2) Inlet exhaust gas temperature 370℃ (3) Inlet exhaust gas dust quantity ~30g/Nm3 (4) Exhaust gas content dusty air ii) Design parameters (1) High pressure steam section Rated evaporation 24t/h Rated steam pressure (gage pressure) 1.6MPa Rated steam temperature 350℃ Blowdown rate 1％ (2) Low pressure steam section Rated evaporation 8t/h Rated steam pressure (gage pressure) 0.35MPa Rated steam temperature 190℃ Blowdown rate
