Incineration is a Thermal Treatment Technology (3Ts) that could be expressed as the way to get rid of waste effectively with the reduction of its mass and volume. However, to control the combustion process efficiently, especially combustion temperature, with low energy content in Municipal Solid Waste (MSW), an additional fuel is needed and leads to increase of operating cost compared with other disposal option. High Temperature Air Combustion (HTAC) has been successfully demonstrated in a lab-scale incinerator for energy saving and pollutant reduction, especially NOx. This article has the objective to design and manufacture the prototype scale High Temperature Air Incinerator with a capacity to treat MSW of 12 Ton per day. The system consists of an automatic feeding machine to feed the waste into the primary combustion chamber (PCC) where the combustion takes place. The push ram is used to push the burning waste and fall down to the lower hearth. Primary combustion air is supplied into PCC at the amount lower than the stoichiometric requirement to produce the combustible gas which is flown into the Secondary Combustion Chamber (SCC) located above PCC. Secondary combustion air is injected to react with combustible gas to convert to the product of complete combustion. A part of hot flue gas which is flew out from SCC is reverted and mixed with fresh air, in order to reduce oxygen concentration, before passing through the heat exchanger tube bundle which is placed inside SCC in order to exchange heat with hot flue gas. To manufacture the designed incinerator, the detail of materials used as well as the frabication method is explained. It has been shown that HTAC can be applied for thermal destruction of waste successfully, in term of energy saving and pollutant free. Benefits of this research work will promote the using of thermal treatment technology of dispose of MSW with lower operating cost and lower pollutants.

In order to optimize the process conditions for regeneration of activated carbon form spent catalyst resulted from 3,4,5,6-tetrachloropyridine-2-carbonitrile synthesis. A two-step process involving the thermal desorption of spent activated carbon and the activation of activated carbon treated by thermal desorption with steam was designed. The influence of desorption temperature, time and the flow rate of nitrogen on the yield of chlorides, the iodine adsorption capacity and the yield of activated carbon were investigated, respectively . The optimal desorption conditions were: temperature of 650°C, time of 90min and the flow rate of nitrogen of 30ml/min. The yield of the chlorides obtained under the optimal conditions was 14.85%. The regeneration of activated carbon treated by thermal desorption with steam; the optimized conditions analyzed by RSM were regeneration temperature of 696°C, time of 84 min and flow rate of steam of 0.58g/min. The experimental results on the optimized conditions were iodine adsorption value of 1003.59mg / g, These methods can not only recover chloride in the spent activated carbon, but also the regeneration activated carbon could partially replace the fresh activated carbon, which would bring an obvious economical benefit and social benefit.

Flue Gas Treatment

Abstract One of the main pollution types is air pollution, which has a significant impact on the surrounding environment and on living beings. Major source of air pollution is combustion processes. There are many flue gas treatment technologies around the world. In this paper a new, innovative flue gas treatment technology – fog unit – is introduced. The goal of the fog unit is to treat flue gases that are emitted from households. In the European Union, including Latvia, at the beginning of 2020, a directive will come into effect that will set limits for emissions and the effectiveness for incinerators in households. The main focus of this study was to determine the most optimal operating mode for the fog unit by changing different operating parameters: sprayed water temperature, sprayed water flowrate and types of nozzles (drop diameters). Results show that the most optimal operating mode in terms of flue gas treatment efficiency and recovered energy is at water temperature: 20 °C, sprayed water flowrate: 250 l/h and nozzle: MPL1.12 M. However, electrical consumption of water circulation pump leaves negative effect on this operating mode.
