Zpřesnění metodiky stanovení termokinetických vlastností uhelného prášku

Abstract

The thesis deals with creating a methodology for determining termokinetic parameters of pulverized coal using an experimental device called Drop tube, which allows the simulation of reaction conditions in the area of high- power boiler, burning pulverized coal. It describes the main influences on the course of combustion of pulverized coal and the first steps to improve the methodology. The methodology is new to the new coolant sampling probe in gas- tight double- shell design for improved insulation properties. The probe is further complemented by a new cryogenic valve for finer control of medium dispensed into the probe. The experimental section describes the use of experimental tests on drop tube assembly and subsequent curve burning coal particles. Graphs include manufacturing drawing cooling probe and cryogenic valves.
