Creation of a Composite System Based on Pyrolysis Resins and Pyrogenetic Water using the Cavitation Effect

In this work, coal from the coal basins of the southern region of Kyrgyzstan (Uzgen Kara-Debe, Alay Zak-Kashkasuu, Kadamjai Bel-Alma, Sulyukta open-pit mine No.4) is taken as the main raw material, and on the basis of the products obtained from it, it is envisaged to create composite systems as a fuel. In the experiments, we placed 1000 g of pre-weighed coal in a reactor to determine the release of volatile substances, and then subjected it to slow pyrolysis to a given temperature in a stainless steel reactor, ensuring tightness. Pyrolysis was carried out for brown coal from 100 ° C to 550 ° C and for hard coal from 100 ° C to 1100 ° C, i.e. it was carried out until the release of liquid and gaseous products ceased. The calorific value of coals was determined by a colorimetric bomb. Based on the cavitation effect, a stable composite system was created, consisting of 10 micron coal powder + coal tar + pyrogenetic water + water + plasticizers. It was found that the cavitation effect is high for obtaining a homogeneous, stable, dispersed composite system. Voltage of 16 volts is enough for the combustion process to occur, and the efficiency during combustion can be increased by 4-6% due to fogging of the chrome coil heated to 4000C, and this will bring economic benefits. During combustion, the content of harmful substances (CO, H2S, NO, SO2, C2-C12) is released in an amount that does not exceed the norm.
