Abstract

This plant was designed as a possible option for thermal utilization of rural and urban wastes in Nigeria. Pollutant gases such as carbon monoxide (CO) and nitrogen dioxide (NOx) have numerous health implications when unsafe amounts are released into the atmosphere. Packed-bed technology was installed along with the Wet Scrubber System (WSS) catalyzing the oxidation of packed-bed and pollutant gases. After the water temperature was controlled, the concentration of packed-bed increased resulting in an efficient pollution treatment system. Levels of pollutant gas emission were found to be beneath National Guidelines for Emissions. Data were collected from the experiments conducted in the Centre for Industrial Studies (CIS) workshop, Department of Mechanical Engineering, Abubakar Tafawa Balewa University, Bauchi, Bauchi State, Nigeria, which were analyzed and examined. Determination of the heat contents were carried out using two methods: IMR 1400 Gas Analyzer PL model and Dulong’s formula. Some samples of the wastes were analyzed with IMR 1400 Gas Analyzer PL model in the above named Centre. This is important because it is a direct measure of the temperature requirements that the specific waste was place on the system. The comparison of the net enthalpy values for textile, paper and wood wastes blended with plastic at different compounding ratios used which shows that 25%PL + 75%TE had the enthalpy calorific values of 8.077 MJ/mol, 10.287 MJ/mol, 10.241 MJ/mol and 11.045 MJ/mol for CO, CO2, NOX and SOX and 100%PA had the lowest value of 2.974 MJ/mol, 3.788 MJ/mol, 3.771 MJ/mol and 4.067 MJ/mol for CO, CO2, NOX and SOX respectively. The maximum temperature of the furnace attained from the energy balance based on this value around the combustion chamber was 277 K.

Keywords: Solid-waste, steam, temperature, flue gases, calorific value, energy, combustion.
