摘要

本文总结了30kW实验燃烧装置固体颗粒排放的测量结果。该装置已用于流化床中生物质的氧燃料燃烧研究，当与碳捕获技术相结合时，这是降低大气中二氧化碳含量的有前途的方法之一。为了实现碳捕获系统，首先需要从烟道气中分离各种杂质。因此，这项工作的目标是识别烟气中含有的固体颗粒。用于该测量的仪器的一部分是喷射稀释器。为了评估测量结果，了解稀释器的稀释率是关键。为此，提出了一种确定喷射稀释器稀释率的方法，并进行了实验验证。

Measurement of solid particle emissions from oxy-fuel combustion of biomass in fluidized bed

The presented work summarizes the results of the measurement of solid particle emissions from an experimental 30 kW combustion unit. This unit has been used for the research of oxy-fuel combustion of biomass in a fluidized bed, which, when accompanied with carbon capture technologies, is one of the promising ways for decreasing the amount of CO2 in the atmosphere. To implement a carbon capture system, it is first needed to separate various impurities from the flue gas. Therefore, the goal of this work was to identify solid particles contained in the flue gas.Part of the apparatus used for this measurement was an ejector dilutor. To evaluate the results of this measurement, it is key to know the dilution ratio of the dilutor. For this purpose, a method for determining the dilution ratio of an ejector dilutor was proposed and experimentally verified.

期刊介绍： Acta Polytechnica is a scientific journal published by CTU in Prague. The main title, Acta Polytechnica, is accompanied by the subtitle Journal of Advanced Engineering, which defines the scope of the journal more precisely - Acta Polytechnica covers a wide spectrum of engineering topics, physics and mathematics. Our aim is to be a high-quality multi-disciplinary journal publishing the results of basic research and also applied research. We place emphasis on the quality of all published papers. The journal should also serve as a bridge between basic research in natural sciences and applied research in all technical disciplines. The innovative research results published by young researchers or by postdoctoral fellows, and also the high-quality papers by researchers from the international scientific community, reflect the good position of CTU in the World University Rankings. We hope that you will ﬁnd our journal interesting, and that it will serve as a valuable source of scientiﬁc information.
