The main technical indexes of the second generation new dry process cement technology and equipment innovation R & D requirements are specific heat consumption of clinker≤2680kJ/kg·cl, that is comparable to the standard coal consumption of clinker≤18kW·h/t; dust emission concentration of main dust collection equipment<10mg/Nm3, dust collector resistance<800Pa, the service life of the filter bag≥4years; NOx reduction efficiency of low NOx burner≥10%, staged combustion efficiency≥30%, denitrification efficiency of SNCR Technology≥70%, denitrification efficiency of SCR Technology≥85%; fuel substitution rate>40%; new clinker cement can reduce the CO2 emissions by more than 25%; labor productivity increased by 1.5 times to 2 times, 5000 t/d cement clinker production line capacity of 60 to 80 people can reduce the cost of management30%, and can reduce the cost of production by 15% ~ 20%, etc.
Up to now, the second generations of new dry cement technology and equipment research and development overall progress of more than 70%, part of the research and development projects have been fully completed, technical indicators have reached or exceeded the technical indicators identified by R & D standards, some R & D projects or part of the sub items have been or are being carried out in an engineering demonstration application which need further optimization and improvement of engineering demonstration application verification.
Tianjin cement industry design and Research Institute and China Equipment Group Co., Ltd. joint commitment to high energy efficiency and low nitrogen pre heating and pre decomposition and advanced sintering technology research and development projects, the clinker burning system power consumption has been reached to 17.9kW·h/t, better than R & D standards and technical indicators, clinker burning heat consumption has been achieved2780kJ/kgcl approach to R & D standards; Hefei cement industry research and Design Institute, Tianjin cement industry design and Research Institute, respectively, to bear the high efficiency of bed grinding technology research and development projects, cement (PO42.5) grinding power consumption has been better than standard technical indicators research, the best indicator is less than 25kWh/t; High performance and high efficiency filter bag dust collection technology research and development project of high performance and high efficiency, which is undertaken by Nanjing film material Co. Ltd., dust emission concentration of main dust collection equipment, dust collector resistance, the service life of the filter bag has reached the standard technical indicators research and export Europe and the United States and other countries; By the Tianjin cement industry design and Research Institute, research and Design Institute of Hefei cement industry, low NOx burners Conch Cement Group Co. bear low NOx burner and staged combustion technology stock efficiency has reached or exceeded the standard technical indicators research. Staged combustion technology stock average efficiency above 30%. The best level can up to 50%.
By China Building Materials Science Research Institute, Tianjin cement industry design and Research Institute, Beijing Building Materials Research Institute respectively bear the new Baillet high belite sulphoaluminate cement clinker clinker and low carbon development projects also have a good progress. Various R & D units through the optimization of batching technology and calcination system, a new type of low calcium cement clinker production technology was creatively developed and a large scale industrial experiment was carried out and gained valuable experience in industrial production, get the quality of qualified low calcium cement clinker products which meet the requirements of the project.Preliminary study of low calcium cement in concrete indicate the working performance and strength of the cement is better than that of ordinary portland cement.
