Abstract:
Purpose. Justification possibilities of increasing of energy efficiency of heat generators by means regulating modes dosing of air and fuel.
Methodology. Investigation of combustion process solid fuel is based on the laws of conservation of mass, energy and momentum. Planning activities for energy efficiency is based on the principles of energy management using data derived with methods of simulation and physical modeling.
Findings. The factors affecting the efficient combustion of solid biofuels analyzed. A method for dosing the components of a solid fuel and air on the basis of analysis the composition of the flue gases was suggested. A simulation model of electro complex heat source with a fan motor control system based on the use of adaptive neuro-fuzzy systems was created.
Originality. Substantiated efficiency of realization of rational dosage of components of burning is with the use of the regulated modes of operations of auger for serves of fuel and ventilator on the basis of analysis of composition of smoke gases. It allowed to increase energy efficiency of heat generator; decrease harmful emissions in an atmosphere; to provide the secure fuel supply at the chamber of burning, that does impossible ignition of fuel in a bunker in case of emergency stopping.
Practical value. The proposed method of supplying energy-efficient fuel mixture in the solid fuel boilers was tested for production facilities “Ukrainian technological systems” in the Ternopil region. As components of biofuels used chopped straw (humidity 25–37%) and sawdust (humidity 12–15%). During the experiment test system of control demonstrated satisfactory performance on the process equipment company. The results obtained proved that the use of technology allows us to reduce energy costs by an average of 17%. This method can be used in enterprises, which focusing on the use of alternative fuels.
