Use advice for data set
| When utilizing this dataset in Life Cycle Assessment (LCA), please ensure that the production systems and boundaries are consistent with those of the dataset, which specifically covers ordinary Portland cement production at two cement plants in Northeast China, utilizing the new dry process. The data user should account for the advanced technological processes, waste heat recovery, and electricity generation in the impact assessment. This dataset should only be applied to large-scale cement production scenarios where advanced energy efficiency measures are employed. Data users need to be aware that including or excluding the pure low-temperature waste heat power generation can significantly affect the outcomes of the environmental impact assessment. |
Technical purpose of product or process
| This dataset describes the technological application of a modern cement production process. The cement produced in this manner, ordinary Portland cement, serves a wide range of construction purposes, including the construction of buildings, bridges, and roads. Furthermore, the production process incorporates advanced equipment and technology, such as the adoption of an enhanced five-stage suspension preheating and kiln decomposition system, a vertical raw mill, and a large ball mill fitted with a roller press. This setup typifies a high-efficiency cement manufacturing plant designed for large-scale production with a daily output of 5000 tons of cement clinker. Moreover, the plant utilizes pure low-temperature waste heat power generation, which is an environmentally conscious feature targeting the recovery and conversion of waste heat from the production process into electricity. |

| Equipped with a 5000T/D new dry process cement clinker production line, which adopts advanced enhanced suspension preheater five-stage kiln decomposition technology and advanced cement production equipment such as vertical raw material mill and large ball mill with roller press. The case adopts the technology of pure low temperature waste heat power generation. The kiln head exhaust gas from thechiller is used for heating AQC boilers, and the kiln tail exhaust gas from the preheating device is used for heating PH boilers. The heat energy in the exhaust gas is converted into overheating steam by high -efficiency waste heat boiler to promote the power generation of the steam generator set. |
