UCG PROCESS VISUALIZATION
Abstract
Underground coal gasification (UCG) is an industrial process that provides an alternative to conventional underground mining at coal seams that are located especially deep underground. This process converts coal into product gas (syngas). In this contribution, a proposal of the monitoring system of the underground coal gasification process is presented. The task of the monitoring system is shown indirect measured values from UCG process as two-dimensional temperature field of gasified coal seam. The two-dimensional temperature field is results from the Fourier partial differential equation of the heat conduction that was used for the calculation of the temperature field in the gasified coal seam with using algorithm of queue burning movement for modelling boundary condition in gasification channel. This Fourier partial differential equation was solved by implicit algorithm of the elementary balances method. The monitoring system is based on programming means MATLAB with using its visualization components (GUIDE). This system was verified on data obtained from laboratory measurement realized on the laboratory gasified.
