Study on combustion properties of magnesium-rich propellant based on analysis of kneading mixture

Abstract

In order to improve the combustion performance of the magnesium fuel, the heat value and combustion temperature of the mixture and the propellant were analyzed. The results show that: At the kneading machine speed of 1600 r/min, the magnesium and aluminum-rich fuel was prepared by adding propellant, with a calorific value of 2420 kg / t. The propellant has high calorific value, low combustion temperature, low non-combustible content, no by-products of combustion products, and low environmental pollution. Rich fuel shall meet the following requirements in use: First of all, the rich fuel should be added to the rich fuel to meet the combustion performance requirements; Secondly, to ensure that the mixing effect of rich fuel and mixture is consistent; Again, to ensure that the rich fuel does not produce harmful gases at higher temperatures. Rich fuels contain a variety of metal elements and trace elements (P / K), and their chemical composition is also different from traditional fuels such as coal and oil. According to the working principle and characteristics of the kneading machine, the type and added amount of rich fuel can be reasonably selected; At the same time, it can also consider the use of different metal elements and trace elements with different mixing amounts and different fuel composition, and reasonably choose the type and added amount of rich fuel.
