Beschreibung
Zusammenfassung:	The invention relates to a potassium fixing method for biomass fuels. The potassium fixing method includes the steps of pretreatment, drying and high-temperature utilization, wherein during pretreatment, a silica sol solution is evenly sprayed on biomass fuel containing potassium elements or the biomass fuel is soaked into the silica sol solution. The potassium fixing method for the biomass fuels has the advantages of simplicity, low silica sol price, low cost and capabilities of effectively fixing potassium, benefiting improvement on reaction efficiency and weakening adverse effect of the potassium component in the biomass fuels on equipment such as a boiler during combustion. 本发明涉及种生物质燃料固钾方法，其包括预处理、干燥处理和高温利用步骤：其中预处理为向含有钾元素的生物质燃料上均匀喷洒硅溶胶溶液或将生物质燃料浸泡在硅溶胶溶液中。本发明方法可有效实现钾的固化，有利于提高反应效率和改善了生物质燃料中含钾组分在燃烧过程中对锅炉等设备造成不良影响。此外，本发明方法简单，所采用的硅溶胶价格便宜，成本低。
