Abstract

For the experimental investigation on the combustion characteristics of Municipal Solid Waste(MSW) in Fluidized Bed, a lab scale Fluidized Bed facility was constructed. Single and mixed municipal solid waste burning in Fluidized Bed showed that dry waste can be burnt quickly at the bed temperature of 500 degrees C, and furnace temperature increased about 30-50 degrees C. Many kinds of combustion runs were conducted in this Fluidized Bed combustion facility. The parameters examined were air flow rate(from 5.5 m3/h to 7.5 m3/h), form of fuels(scrap or whole), moisture content and so on. Concentration of CO2, CO, SO2 and NOx in the flue gas were monitored and recorded every 5 seconds. The temperatures along the reactor were recorded every 10 seconds.

摘要

为了对城市固体废弃物（MSW）在流化床中的燃烧特性进行实验研究，搭建了一套实验室规模的流化床装置。在流化床中对单一及混合城市固体废弃物进行燃烧实验，结果表明，干垃圾在500℃的床温下能够快速燃烧，炉膛温度升高约30 - 50℃。在该流化床燃烧装置中进行了多种燃烧试验。所考察的参数包括空气流速（从5.5立方米/小时到7.5立方米/小时）、燃料形式（碎片或整体）、含水量等。每5秒监测并记录一次烟道气中二氧化碳、一氧化碳、二氧化硫和氮氧化物的浓度。每10秒记录一次沿反应器的温度。
