【摘要】：中国造纸业的产能不断扩大,现已位居世界第一位,我国人口众多,能源资源相对不足,人均拥有量远低于世界平均水平,金东纸业(江苏)有限公司年消耗标煤量达100万吨。能源占工厂总成本的20%,是金东纸业除纸浆之外的最大成本项。企业自备发电厂采用热电联产,通过将能源分级,热电分产能源利用方法,将燃料化学能转换为蒸汽后,在汽轮机做功,汽轮机排放乏汽用于造纸工艺。由于自备发电厂成本均摊在主产品,节能压力不大,缺乏对于能源产量、能源产出和能源消耗的全局观念。通过自备发电厂与国家公共发电厂纵向对比,与欧美造纸企业自备发电厂同业对比,依据标杆理论与鱼骨图分析,使用能源审计与能量平衡两个核心工具,分析能源的存储,转换,输送全过程。从设备和管理两方面入手,找出薄弱环节,提升自备电厂的节能水平。探讨了秸秆、树皮、秸秆压块等生物质能源,在自备发电厂中的开发和利用,改善企业相对单一煤炭的能源结构,合理配置企业能源,符合国家发展的政策。发展可再生能源对调整能源结构、增加能源供应、减排和环境效益、促进经济发展的都有特殊意义。
[Abstract]:The production capacity of China paper industry is expanding, now the largest in the world. Our country has a large population, the energy resources are relatively insufficient, the per capita ownership is far below the world average. The annual consumption of Jindong paper (Jiangsu) Co., Ltd. is 1 million tons. Energy accounts for 20% of the total factory cost, which is the largest cost item in the paper industry of Jindong. By means of energy classification, thermoelectric production and energy utilization and conversion of fuel chemical energy into steam, the steam turbine does work and the steam turbine exhaust steam is used in papermaking process. Because the cost of the power plant is shared in the main product, the energy saving pressure is small and the energy output, energy output and energy are lack. Through the comparison between the self generating plant and the national public power plant, compared with the European and American paper-making plant, according to the benchmarking theory and the fish bone map analysis, the energy audit and energy balance two core tools are used to analyze the energy storage, transfer and transport process. From the two aspects of equipment and management, To find out the weak link and improve the energy saving level of the self-made power plant. The biomass energy, such as straw, bark, straw pressure block and so on, is explored and utilized in the self-made power plant. The energy structure of the enterprise relative to single coal is improved, the energy of the enterprise is rationally configured and the policy of national development is conformed. The development of renewable energy to adjust energy structure and increase energy Source supply, emission reduction and environmental benefits, and promoting economic development have special significance.
