RESEARCH OF THE THERMAL POTENTIAL OF VARIOUS MIXTURES OF HOUSEHOLD SOLID WASTE TO WOOD PELLETS

Abstract

The article deals with the current issue of solid household waste management and focuses on the
fact that the most effective method of reducing the amount of waste is heat treatment. Attention is paid to
such an important parameter when burning solid household waste as caloric content.
A study of the calorific value of various types of waste, wood solid fuel pellets made from different
types of wood was conducted. Waste samples were obtained during an on-site expedition to the municipal
solid waste landfill (MSW) in the village of Rybne An analysis of the calorific value of the waste mixture,
which corresponds to the morphological composition of the landfill (MSW) in the village of Rybne what
suitable for burning. Also, an analysis of the calorific value of the mixture of wood solid fuel pellets,
which was made from different types of wood, was carried out. The level of thermal energy for different
types of waste (plastic, bio-waste, rubber, paper, textiles, wood, etc.) and different types of solid wood
pellets (oak, beech, pine, etc.) was studied. The calorific index of different mixtures of waste and pellets
at different percentage values of the components in the mixture was calculated. Microsoft Excel software
was used to simplify the calculation. Real caloric values obtained during a laboratory study using an IKA
C1 calorimeter were used in the determination.

Through transformations, ratios and calculations, dependencies were established for each of the
types of waste and solid fuel wood pellets. Using the values of calorific value, which were obtained
during combustion, the minimum and maximum levels of caloric content at different percentage values of
the components were found. A calculation algorithm has been created, which can be used to determine
the amount of thermal energy at various percentage ratios of waste types to wood solid fuel pellets.
