阅读：21发布：2021-11-15

专利汇可以提供Process for burning cement clinker专利检索，专利查询，专利分析的服务。并且A new process for burning cement clinker consisting of a rotary kiln, a raw material suspension preheater comprising multistage cyclone heat exchangers, and a fluidized calciner having a separate heat source is provided. This process improves the allover decarbonizing rate of raw materials fed into the rotary kiln remarkably by extracting a part of the raw materials from at least one of the multistage cyclone heat exchangers of the suspension preheater and introducing it into the fluidized calciner so as to have it calcined. This process can increase the rotary kiln capacity extremely as compared with that of the conventional suspension preheater system as well as to enable the rotary kiln to operate continuously and stably for a long period.，下面是Process for burning cement clinker专利的具体信息内容。

权利要求

1. IN A PROCESS FOR BURNING CEMENT CLINKER WHICH COMPRISES FEEDING CEMENT RAW MATERIAL FROM A FEEDER TO A MULTI-STAGE PREHEATING ZONE, HEAT EXCHANGING SUCCESSIVELY SAID CEMENT RAW MATERIAL WITH A COMBUSTION GAS FROM A COMBUSTION ZONE THROUGH SAID MULTI-STAGE PREHEATING ZONE, BURNING TO CEMENT CLINKER IN A NON-FLUIDIZED STATE THE HEAT EXCHANGE CEMENT RAW MATERIAL IN SAID COMBUSTION ZONE WITH THE SAID OF FUEL AND COOLING SAID CEMENT CLINKER, THE IMPROVEMENT WITH COMPRISES INTRODUCING A PART OF SAID CEMENT RAW MATERIAL HEAT EXCHANGED FROM SAID MULTI-STAGE PREHEATING ZONE INTO A FLUIDIZED CALCINING ZONE HAVING A SEPARATE HEAT SOURCE WHERE SAID PART THEREOF IS CALCINED IN A FLUIDIZED BED, INTRODUCING A WASTE GAS FROM SAID CALCINING ZONE WHICH ENTRAINS THE CALCINED CEMENT RAS MATERIAL TO A FINAL STAGE OF SAID MULTI-STAGE PREHEATING ZONE WHERE THE CALCINED CEMENT RAW MATERIAL IS SEPARATED FROM SAID WASTE GAS AND BROUGHT TO BE MIXED WITH ANOTHER PART OF THE HEAT EXCHANGED CEMENT RAW MATERIAL WHICH HAS BOT BEEN INTRODUCED INTO SAID FLUIDIZED CALCINING ZONE, AND THEN FEEDING THE CALCINED AND THE HEAT EXCHANGED CEMENT RAW MATERIALS TO SAID COMBUSTION ZONE TO PRODUCE A BURNED CEMENT CLINKER.

2. A process for burning cement clinker claimed in claim 1, wherein a part of said cement raw material from said feeder is directly introduced into said fluidized calcining zone.
