Description

The grinding of raw materials and calcinating for clinker are closely linked as one complete procedural phase in the new suspension preheater (NSP) kiln. In addition, the residual heat from the kiln in the calcinating process is used to dry or bake raw materials in the grinding phase with the addition of coal powder.The NSP kiln is a production system of high efficiency, good production continuity, high output, and low overall energy consumption. In addition, with better dust collection and noise elimination equipment, the production system of the NSP kiln can greatly reduce the consumption of resources and pollutant emissions. When using this data set, attention should be paid to the system boundaries specified - the preparation stage of the raw meal (including grinding) and the calcination stage for producing clinker. Users should include both of these stages in their Life Cycle Assessments. It's important to note the high efficiency and low energy consumption of the NSP kiln process; therefore, comparisons with other kiln types should account for these attributes. Additionally, due to the advanced dust and noise control technologies, environmental impact factors should be adjusted accordingly in LCA models. The specific use of coal powder for drying or baking in the grinding phase should also be appropriately reflected.

Technology

Compared with the shaft kiln, the NSP kiln is a production system of high efficiency, good production continuity, high output, and low overall energy consumption. In addition, with better dust collection and noise elimination equipment, the production system of the NSP kiln can greatly reduce the consumption of resources and pollutant emissions.
