다양한 종류의 연소로 형식에서 고체 연료 특성이 연소과정에 미치는 영향

Abstract

Three Lab-scale combustors of different types were made to observe some basic phenomena of fuel combustion in the combustors ; grate type combustor, rotary kiln and FBC. The aims were to introduce how to simulate the combustion behaviors in the real plants by utilizing the reduced apparatuses and characterize the combustors relating to some important parameters such as fuel size, water contents, bed temperature, rotating speed of kiln, flow rate. The mean carbon conversion time and the flame propagation rate were adopted for the quantitative analysis.
