摘要
为分析广东省建筑陶瓷行业清洁能源改造的减污降碳效益,收集建筑陶瓷行业发展和环境相关的资料,结合对16家典型建筑陶瓷企业改造后的调研数据,对比分析改造前后广东省建筑陶瓷行业在污染物排放、碳排放、能耗和用能成本方面的变化。研究结果表明,建筑陶瓷清洁能源改造从源头上减少了多种污染物的排放。其中,现有企业年减少SO21.49万t和NOx1.53万t;其次,清洁能源改造后,窑炉生产线的单位产品能耗明显下降,平均降低24%,特别是大型企业的平均降幅达到33%;第三,建筑陶瓷清洁能源改造减少了现有企业煤炭使用量462.8万t/a,节省79.3万t标准煤/a,并实现563.2万t/a的CO_(2)净减排量;最后,改造后的企业燃料使用成本增加25%~108%,平均增长65%,总成本增加19.5%。在碳市场交易不断扩大及碳价可能上升的背景下,如果企业在清洁能源改造中通过高效节能技改使单位产品能耗降低,实施清洁能源改造,将为企业带来碳排放成本的优势。
To analyze the pollution reduction and carbon reduction benefits of clean energy transformation in the architectural ceramics industry in Guangdong Province.Basing on first-hand on-site data from 16 typical enterprises after transformation and literatures on the development and environment of the architectural ceramics industry,this study conducted a comparative analysis of changes in pollutant emissions,carbon emissions,energy consumption,and energy costs before and after the transformation.The results indicated that,firstly,the clean energy transformation in the architectural ceramic industry had mitigated the emission of multiple pollutants at their origin.Specifically,emissions of SO 2 and NO x had been reduced by 14900 t/a and 15300 t/a.Secondly,following the transformation to clean energy,the energy consumption per unit product in furnace production lines showed a decline,with an average decrease of 24%.Large-scale enterprises,in particular,had achieved an average reduction of 33%.Thirdly,the clean energy transformation in the architectural ceramic industry had cut provincial coal consumption by 4628 million t/a,saving 793000 t/a of standard coal and realizing a net carbon dioxide emission reduction of 5632 million t/a.Lastly,the transformation had resulted in a 25%to 108%increase in fuel use costs,with an average rise of 65%and a total cost increase of 19.5%.Under the backdrop of the expanding carbon market and the possibility of rising carbon prices,it is worth to hight that the implementation of clean energy transformation will bring cost advantages in terms of carbon emissions for the enterprise if enterprises can reduce the unit product energy consumption of kilns through high-efficiency energy-saving technology during transformation.
