Abstract

The aim of the article is to present the physical and chemical properties of the refuse derived fuel (RDF) substrates, which have a significant impact on the energy recovery process in power plants. The experimental part includes technical (moisture and ash content, net and gross calorific values) and elemental analyses (sulfur, chlorine and mercury content), biomass and non-biomass concentration in the samples. In order to carry out the analysis of reactor slagging and fouling risk, chemical composition of the ash and characteristic ash fusion temperatures were determined. The waste samples are heterogeneous material and their properties are diversified – the moisture content ranges from 1.8 to 29.2 wt. %, the net calorific value from 17.231 to 28.307 MJ/kg, the ash content in the samples from 7.7 to 31.2 wt. %. The S content is in the range from 0.04 to 0.58 wt. %, the Cl content from 0.58 to 2.11 wt. % and the Hg content in the samples from 0.09 to 0.20 mg/kg. It can be observed, that the tested waste is a demanding fuel, because of its unfavorable fouling and slagging properties, which are directly related to the content of oxides with the basic properties.

在电力工业的适用性方面具有重要的废物特性

本文的目的是介绍垃圾衍生燃料(RDF)底物的物理和化学性质，这对发电厂的能量回收过程有重要影响。实验部分包括技术分析(水分和灰分含量、净热值和总热值)和元素分析(硫、氯和汞含量)、样品中的生物质和非生物质浓度。为了对反应器结渣和结垢风险进行分析，测定了灰的化学成分和特征灰熔融温度。废样为异质材料，其性质多样，水分含量为1.8 ~ 29.2 wt. %，净热值为17.231 ~ 28.307 MJ/kg，灰分含量为7.7 ~ 31.2 wt. %。样品中S含量为0.04 ~ 0.58 wt. %， Cl含量为0.58 ~ 2.11 wt. %， Hg含量为0.09 ~ 0.20 mg/kg。可以看出，所测试的废物是一种要求很高的燃料，因为其不利的结垢和结渣性能与具有基本性能的氧化物的含量直接相关。
