Abstract

This article addresses the global problem and proposes an innovative and highly efficient solution, particularly, the combustion process using the High-Temperature Fluidized Bed Technology. Many scrap tires and biomass waste are generated worldwide in every specific country or region. Removing such waste is a serious problem as its disposal in the landfill is prohibited. The best solution to this challenge is the eco-friendly utilization of such waste as a local fuel. Georgian Technical University (GTU) professors conducted a theoretical study describing the relationship between the pollutants emitted and combustion temperature, which was practically tested and approved using the created 2 MW capacity device (Patent P6828, 2018-03-20) working on the High-Temperature Fluidized Bed Technology, which fully differs from the commonly introduced Low-Temperature Circulative Fluidized Bed Technology. The most interesting confirmation is that even in the case of biomass and scrap tire mixture usage, the GHG emissions are less compared to Natural Gas combustion. Recently a 5 MW capacity combustion device was for a particular business purpose. Both creatures were recognized and awarded by the Association of Energy Engineers of USA (AEE) and Energy Globe contest in 2021 and by the AEE in May 2024.
