Methodology of biomass fuels creation processes

The increasing demand for thermal and electric energy in many branches of industry and municipal management accounts for drastic diminishing of natural resources. Meanwhile, in numerous technical processes, a huge mass of wastes is produced. A segregated and converted combustible fraction of the wastes, with relatively high calorific value, may be used as a component of formed fuels. The utilization of the formed fuel components from segregated groups of waste in associated processes of co-combustion with conventional fuels causes significant savings resulting from partial replacement of fossil fuels, and reduction of environmental pollution resulting directly from the limitation of waste migration to the environment. Particular attention should be paid to the possibility of reusing biomass waste in the aforementioned processes. The realization of technological processes with the utilization of formed fuel in associated thermal systems should be qualified by technical criteria, which means that elementary processes as well as factors of sustainable development, from a global viewpoint, must not be disturbed. The utilization of post-process waste should be preceded by detailed technical, ecological and economic analysis. The objective function defined in the optimization task assists in the decision process i.e. choosing a suitable solution. In order to optimize the mixing process of fuel components, a mathematical model of the forming process was created. The paper also presents the optimization of parameters in the process of forming fuels using a modified simplex algorithm with a polynomial worktime. The calculation procedures outlined above are embodied in a numerical model programmed in the Pascal object-oriented language.
