Suzhou ash silo cleaning, Neijiang ash silo cleaning, Leshan ash silo cleaning. Jiangsu Zhongjie High-altitude Company held a work conference on February 24-25 for the ash silo cleaning in Suining, Neijiang, and Leshan cities, to further discuss the soon-to-be-released "12th Five-Year Plan" for the ash silo industry and its structural adjustment. The director of Zhongjie Ash Silo Bureau reported at the meeting: "In 2011, the national ash silo production reached 3.52 billion tons, increasing by 280 million tons year-on-year, with the increment being at the highest historical level. The proportion of ash silos in the primary energy production structure approached 80%, continuing to play the role of the main energy source." During the same period, China's net imports of ash silos increased by 15% to 168 million tons. Considering the total imports of ash silos, oil, and gas, China's external energy dependence rose from 7% at the beginning of this century to 14% in 2011. Under the extensive development model, China's ash silo production and consumption scale have been increasing annually. The National Energy Administration predicts that by 2015, the annual demand for ash silos nationwide will reach 3.9 billion tons. After the "13th Five-Year Plan," the national demand for ash silos is expected to grow above 4 billion tons annually. The director emphasized at the meeting: "The '12th Five-Year Plan' period is a crucial time for the ash silo industry to change methods and adjust structures, achieving a transformation from quantitative increase to qualitative change. We must seize the opportunity and actively promote changes in the production and utilization methods of ash silos."
The proportion of ash silo consumption did not decrease but instead increased in 2011, reflecting an inverse adjustment in China’s energy production and consumption structure. According to preliminary projections during the "12th Five-Year Plan" period, the proportion of ash silos in primary energy consumption should gradually decline, reducing from over 70% to around 65%. Based on statistics from the Ash Silo Industry Association, in 2011, China's ash silo production was 3.52 billion tons, accounting for approximately 78.6% of total primary energy production; the total ash silo consumption was 3.57 billion tons, accounting for about 72.8% of total primary energy consumption. The total ash silo production and consumption increased year-on-year by 2.1 and 1.9 percentage points respectively. Wang Xianzheng, President of the China Ash Silo Industry Association, said: "China's rich coal, scarce oil, and limited gas energy resource situation determines that for a relatively long period in the future, ash silos will still be the main energy source of our country."
In terms of power installations, Wang Zhixuan, Secretary-General of the China Electricity Council, also believed: "The coal-based power structure will not change. Non-fossil energy cannot achieve large-scale replacement in the short term." The reasons are that hydroelectricity has good economic benefits, but the total resources are limited; nuclear power has already become economically competitive, but it is constrained by technology and safety issues, so the recent development scale is not large; wind power, solar power, and other new energy sources have high costs, unstable output, and cannot effectively replace fossil fuels in the short term. The director said at the meeting: "We need to correctly recognize the status of ash silos as the main energy source. With the transformation of the economic development model, the proportion of ash silos in the primary energy structure will decrease somewhat, but their position as the main energy source will not change in a relatively long period in the future."
However, the energy production and supply model dominated by coal brings trouble to industrial structure adjustment and transformation of the development model. The Energy Bureau requires improving the clean and efficient application level of ash silos. Following the requirements of energy-intensive, technology-intensive, capital-intensive, long industrial chain, and high added value, efforts should be made to improve the efficiency and benefits of ash silo processing and conversion.
