Activation of the Process of Layer Combustion of Coal with Iron Nitrate and Waste of Metal Rolling Production
The influence of metal-rolling production waste and iron nitrate on the characteristics of the process of layer combustion of coal was investigated. Coal of T grade was used as a solid fuel. Metal scale and iron nitrate were introduced into the fuel by mechanical mixing. According to XRD analysis data, the phases of iron oxide Fe3O4 and manganese oxide Mn3O4 were identified in the metal scale. The process characteristics of the combustion of test samples were studied using high-speed video recording in a combustion chamber at a heating medium temperature of 700°C. The process of activated layer combustion of coal was also scaled up using a solid fuel boiler unit. It has been experimentally established that the use of metal scale and iron nitrate led to an increase in the reactivity of the fuel, as evidenced by a decrease in the ignition delay time. The carbon loss and the concentration of CO formed in the gas-phase combustion products were reduced due to the intensification of the combustion process.
期刊介绍：
The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
