Analytical investigations on chopped waste of biomass and slag recycling from the energetic domain

Abstract

In an economy increasingly globalized a country's energy strategy is done in the context of changes and developments taking place worldwide. Due to increasing energy demand, energy has developed rapidly without the problem of environmental protection. Total energy demand in 2030 will be around 50% higher than in 2003. The current world energy situation compel mankind to find new energy sources in order to replace fossil fuels currently used widely. It is considered that in perspective, energy from biomass will be ranked second only to energy from fossil fuels. Special attention was given to recovery of the waste and biomass burning from the perspective of preserving natural resources and reduce the amount of waste generated. The quality criteria for the recovery of waste are usually connected to the structural properties of the residue and the content of hazardous substances and the amount of unburned fuel or the solubility of heavy metals, etc. This paper presents the results of same laboratory tests on different samples of coal and waste mixed blends of biomass and small clay. Test samples were subjected to specific laboratory solid (moisture, ash, elemental analysis, calorific value) necessary for evaluating and reporting CO2 emissions in accordance with the law. Analytical investigations were performed to highlight the following aspects: the influence of biomass present in the fuel mix to reduce CO2 emissions; the use of biomass mixed with slag often recover unburned carbon content in the process of energy production; the influence of carbon (total carbon, organic carbon) in calculating CO2 emissions. Following laboratory tests found a better relationship between organic carbon (TOC) and CO2 emissions than total carbon that is present in fuel.
