    Full text link
    Purpose of the study is to obtain fundamental knowledge about Kuznetsk bituminous coal entrained-flow gasification in O 2 -CO 2 mixtures for oxy-fuel IGCC. To achieve this purpose, it is necessary to carry out experimental and numerical studies. To obtain universal knowledge, "CKTI" single-stage gasifier with fuel consumption of 5-15 kg/h was chosen as an experimental installation. In order to identify the most interesting and informative experimental regimes, a number of computational studies have been carried out, whose results are given in the paper. A numerical (CFD) model has been developed, which includes all the submodels necessary for the study. Two series of numerical calculations were carried out. In the first series, the composition of the blast (O 2 = 0-100%, CO 2 = 0-100%) and the oxygen ratio were varied at constant consumption of coal and blast. In the second series, the composition of the blast (O 2 = 0-100%, CO 2 = 0-100%) and the coal consumption were varied at constant oxygen ratio and blast flow rate. The study allowed predicting and analyzing the temperature distribution and the syngas components content along the gasifier height with different CO 2 concentrations in the blast.

    A method of studying thermochemical conversion of single biomass particles in an intense air flow

    There are many methods for obtaining kinetic data of thermochemical conversion of fuel particles. These methods to some extent reproduce the conditions of industrial processes. At the same time, there is a lack of methods reproducing the conditions of wood particles gasification in downdraft gasifier. In this process, raw fuel enters the hot reactor region with intense air jets blowing through the tuyeres. It is difficult to directly measure the weight of particles under these conditions due to the effect of gas flow. The authors proposed a research method in accordance with which the sample is introduced into a heated furnace and placed in the tuyere flow. The sample is combusted for a certain time then removed from the furnace and quickly quenched. The method allows reproducing the dynamics of changes in temperature, mass, volume, shape and structure of the inner layers of particles. It provides visual observations of the process, high heating rate of wood samples (750-5500 Β°C min-1) and large amount of data sufficient for statistical processing.
