TECHNICAL AND ECONOMIC ASSESSMENT OF THE USE OF ALTERNATIVE FUELS FROM WASTE AT THERMAL ELECTRIC POWER PLANTS IN EXCHANGE FOR TRADITIONAL FUELS

A feasibility study was carried out for the transition of typical power engineering objects, diff ering in thermal capacities and electric powers, from traditional fuel (coal, natural gas, fuel oil) to the combustion of biomass, composite liquid fuel, and generator gas. Three options for producing generator gas during gasifi cation of biomass, composite liquid fuel, and coal were studied cash fl ows were calculated for the transition of each of the power plants under consideration to alternative fuel and the payback period for such a transition. Relative indicators of the effi ciency of the generator gas were determined taking into account a set of signifi cant parameters: heat of combustion, fuel consumption, anthropogenic emissions, ash residue, maximum combustion temperature, minimum ignition temperature, combustion initiation delay time, cost, technical and economic indicators of storage, transportation and fuel combustion, fi re and explosion safety.
