Development of gas-generator cartridges operating in the deflagration combustion mode
Keywords:
sodium nitrate, combustion, carbon, walnut, flame temperatureAbstract
This study investigates the performance of a three-component mixture of sodium nitrate, magnesium and carbon obtained by carbonisation of walnut shells or by grinding of gas mask elements. Experimental studies of combustion processes were carried out and formulations of gas-generating compositions with subsonic burning speed and the most efficient characteristics and high specific gas yield were developed. Field tests of the developed gas-generating compositions were also carried out to determine the possibility of their application in practice.
Scientifically substantiated criteria determining the choice of component composition of gas-generating compositions in patoroons, as well as technological processes and optimal conditions of mineral raw materials extraction with the use of gas-generating compositions in conditions of open-pit mining and variation of mine materials depending on the composition of initial components, stage of development, metamorphism, storage methods, etc. are presented.
The developed gas-generating compositions have high energy characteristics and can be used for effective processing of separate types of mineral and natural raw materials at ore deposits of Kazakhstan.
