洁净煤(cleaned coal)是指通过物理或化学处理技术降低污染物含量的煤炭产品。该技术旨在减少煤炭燃烧时产生的硫氧化物、氮氧化物、颗粒物等有害物质,从而提升能源利用效率并缓解环境压力。
核心技术
应用与挑战
洁净煤主要用于发电厂和钢铁冶炼行业。中国国家发改委数据显示,2024年国内超低排放燃煤机组占比已达90%以上。然而,其推广受限于高成本(处理费用增加30%-50%)及部分新兴技术商业化进程缓慢。
环境效益
英国石油公司(BP)统计表明,采用洁净煤技术的电厂,颗粒物排放量比传统燃煤电厂减少75%,二氧化硫排放下降60%。
“Cleaned coal”(清洁煤)是一个涉及能源与环境技术的术语,通常指通过物理、化学或技术手段处理原煤,以减少燃烧时产生的污染物(如硫、灰分、颗粒物等)和碳排放,从而提升煤炭的环保性能。以下是详细解释:
清洁煤的实现依赖于多种技术,可大致分为三类:
“Cleaned coal”是一个技术性术语,其核心是通过人为干预降低煤炭的环境影响。尽管它在特定场景下具有实用价值,但长期仍需结合可再生能源转型实现碳中和目标。如需进一步了解具体技术或案例,建议参考能源领域的权威报告或政策文件。
