【 摘 要 】

China's cement industry, which produced 1,388 million metric tons (Mt) of cement in 2008, accounts for almost half of the world's total cement production. Nearly 40% of China's cement production is from relatively obsolete vertical shaft kiln (VSK) cement plants, with the remainder from more modern rotary kiln cement plants, including plants equipped with new suspension pre-heater and pre-calciner (NSP) kilns. Shandong Province is the largest cement-producing Province in China, producing 10% of Chinas total cement output in 2008. The average annual growth rate (AAGR) of cement production in Shandong Province between 2000 and 2008 was 10%. This growth was dominated by the increase in rotary kiln production, which was mostly due to the increased share of NSP kilns. Production from rotary kilns grew from 11% of total cement production in 2000 to 58% in 2008. This report documents an analysis of the potential to improve the energy efficiency of NSP kiln cement plants in Shandong Province. Sixteen NSP kiln cement plants were surveyed regarding their cement production, energy consumption, and current adoption of 34 energy-efficient technologies and measures.
