Energetical Examination of Pyrolysis Carbon Black and Pine Shavings Blend Pellets

Abstract

Pellets for firing are not only made of wood or by-products of herbaceous plants, it can also be used for energy purposes by using different waste materials or mixtures thereof. These materials do not appear in conventional pellet firing or residential sectors. Waste pellets could be used in larger industrial facilities and in waste combustion plants. During the work pellets are produced of various proportions using furniture industrial pine-based wood shavings and carbon black from the pyrolysis of waste tires. The carbon black is purely purified by the usual wood-pellet making methods, in most places the wet materials are reused in rubber industry. The energetic utilization of wood-based and carbon black mixture pellets was only slightly explored. During the tests, pellets are prepared for pine-based wood which were analyzed by energetic and mechanical properties. In the wood industry, large quantities of contaminated byproducts also appeared: surface-treated materials, glue, paint residues, which cannot be wood pellets in residential use according to EN-14961-1 standard. The study dealt with pyrolysis carbon black (up to 20% mixing) could be used with this contaminated wood.
