Abstract

A semiempirical method is proposed for determining the flow characteristics of a flow-through gas generator operating on gasification of a solid low-melting material by an ambient temperature airflow. Experimental studies of the gasification of a polypropylene charge are performed to demonstrate the approach. In the test fires, the yield of gasification products ranged from 43 to 120 g/s and the ratio of mass flow rates of air and polypropylene gasification products was 2.3–2.9. The analysis of errors inherent in the approach is carried out.
