Process for producing heat and cement clinkers in one boiler, its products, the equipment used and its uses

摘要

The present invention discloses a process for producing both steam power and the fast-burnt cement clinker/fast-burnt modified coal ash simultaneously in one apparatus, the fast-burnt cement clinker/fast-burnt modified coal ash prepared by said process as well as cement products prepared using them as active substance. It also discloses the apparatus suitable for embodying this process. Said process of the present invention possesses the technological features of fast-burning and fast-cooling and contributes a good hydraulic cementitious activity to the said fast-burnt cement clinker/fast-burnt modified coal ash which are capable of being directly used as active substance in cement production of high quality.
