生物质与煤共烧有助于减少温室气体排放，并可作为发展生物质供应基础设施的低成本垫脚石。本文对捷克共和国、法国、德国和波兰的燃煤锅炉中生物质共燃潜力进行了技术经济评估。从查尔默斯电厂数据库中提取的燃煤电厂的地理位置、锅炉装机容量、锅炉技术类型和调试年份是当前燃煤电厂基础设施的特征。评估考虑了锅炉技术类型、生物质类型、共烧分数、实施成本、共烧的盈亏平衡价格和碱指数，以确定高温腐蚀的风险。影响共烧潜力的主要因素是生物质价格、碳价格和碱指数。结果表明，四个国家的共烧潜力约为16twh - 1年，从转换角度来看，德国的潜力最大，其次是波兰。据估计，当碳价格为20€t - 1 CO2时，生物质与煤共烧在生物质价格低于13€MWhinput - 1时具有竞争力。平均而言，1太瓦时生物质共烧发电可替代90万吨化石燃料二氧化碳排放。©2019化学工业协会和约翰威利父子有限公司
Biomass co‐firing with coal can help to reduce greenhouse gas emissions and can act as a low‐cost stepping‐stone for developing biomass supply infrastructures. This paper presents a techno‐economic assessment of the biomass co‐firing potential in coal‐fired boilers in Czech Republic, France, Germany and Poland. The current coal power plant infrastructure is characterized by means of geographic location of the coal power plants, installed boiler capacity, type of boiler technology and year of commissioning, as extracted from the Chalmers Power Plant Database. The assessment considers type of boiler technology, type of biomass, co‐firing fraction, implementation costs, breakeven prices for co‐firing and an alkali index to determine the risk of high‐temperature corrosion. The main factors affecting the co‐firing potential are the biomass price, carbon price and alkali index. Results indicate that the total co‐firing potential in the four countries is around 16 TWh year−1, with the largest potential from a conversion perspective in Germany, followed by Poland. Biomass co‐firing with coal is estimated to be competitive at biomass prices below 13 € MWhinput −1 when the carbon price is 20 € t−1 CO2. On average, 1 TWh of electricity from biomass co‐firing substitutes 0.9 Mt of fossil CO2 emissions. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
