ABSTRACT

This paper presents an analysis of the pine and sunflower husks pellets combustion without and with 5% addition of waste glycerol. Usefulness of pellets contained glycerol additions has been compared in terms of applicable quality standards for biomass pellets. 10 kW domestic biomass boiler has been employed for burning tested pellets. The consumption of analyzed fuels during boiler operation was determined. Effects of waste glycerol addition on CO₂, CO, and NO_x concentrations in exhaust gases have been also examined. The experimental results show that regardless of the type of raw material, a 5% addition of waste glycerol to pellets has nearly twofold decrease NO_x concentration in flue gas and does not significantly affect changes of CO₂ and CO concentrations. Therefore, the use of the waste glycerol as a binder for the production of pellets can be a simple and cost-effective solution of its utilization.

摘要

本文介绍了在不添加和添加 5% 废甘油的情况下对松树和向日葵壳颗粒燃烧的分析。已经根据生物质颗粒的适用质量标准比较了含有甘油添加剂的颗粒的有用性。10 kW 家用生物质锅炉已用于燃烧测试颗粒。确定锅炉运行期间分析燃料的消耗量。还研究了废甘油添加对废气中的CO ₂、CO 和NO _x浓度的影响。实验结果表明，无论何种原料，在球团矿中加入5%的废甘油，烟气中NO _x浓度降低近2倍，且对CO _{2 的}变化没有显着影响。和 CO 浓度。因此，使用废甘油作为生产颗粒的粘合剂可以是其利用的简单且具有成本效益的解决方案。
