comparison of Direct Combustion in a circulating fluidized bed system and decoupling Combustion in a dual fluidized bed system for distilled spirit lees
2016Co-Authors: Zhennan Han, Xi Zeng, Changbin Yao, Yin WangAbstract:At present in China, a fluidized bed combustor is not suitable to treat a high-water-containing (30–60 wt %) industrial biomass residue, such as distilled spirit lees (DSL), which can cause a low bed temperature and inflammation retardation. Our previous fundamental studies showed that the so-called dual fluidized bed gasification decoupling Combustion technology (or decoupling Combustion for short) can ensure the highly efficient and stable Combustion for high-water-containing biomass fuel and lower NOx emission as well. In this study, the Combustion characteristics of DSL in a circulating fluidized bed (CFB) system and a dual fluidized bed (DFB) system will be examined and compared systematically. For Direct Combustion of DSL in a CFB system, the high moisture of 30 wt % decreased the bottom temperature of the combustor significantly and brought in unstable Combustion, thus leading to s large amount of auxiliary fuel (such as coal) needed to raise the temperature to reach an adiabatic flame temperature ...

energy potential from rice husk through Direct Combustion and fast pyrolysis a review
2017Co-Authors: Isabel Quispe, Rodrigo Navia, Ramzy KahhaAbstract:Rapid population growth and consumption of goods and services imply that demand for energy and resources increases continuously. Energy consumption linked to non-renewable resources contributes to greenhouse gas emissions and enhances resource depletion. In this context, the use of agricultural solid residues such as rice husk, coffee husk, wheat straw, sugar cane bagasse, among others, has been widely studied as an alternative energy source in order to decrease the use of fossil fuels. However, rice husk is among those agricultural residues that are least used to obtain energy in developing countries. Approximately 134 million tonnes of rice husk are produced annually in the world, of which over 90% are burned in open air or discharged into rivers and oceans in order to dispose of them. This review examines the energetic potential of agricultural residues, focused on rice husk. The review describes Direct Combustion and fast pyrolysis technologies to transform rice husk into energy considering its physical and chemical properties. In addition, a review of existing studies analyzing these technologies from an environmental life cycle thinking perspective, contributing to their sustainable use, is performed.

Comparison of Direct Combustion in a Circulating Fluidized Bed System and Decoupling Combustion in a Dual Fluidized Bed System for Distilled Spirit Lees
2016Co-Authors: Han Zhennan, Xi Zeng, Yao Changbin, Wang Yin, Xu Guangwen, Zeng XAbstract:At present in China, a fluidized bed combustor is not suitable to treat a high-water-containing (30-60 wt %) industrial biomass residue, such as distilled spirit lees (DSL), which can cause a low bed temperature and inflammation retardation. Our previous fundamental studies showed that the so-called dual fluidized bed gasification decoupling Combustion technology (or decoupling Combustion for short) can ensure the highly efficient and stable Combustion for high-water-containing biomass fuel and lower NO emission as well. In this study, the Combustion characteristics of DSL in a circulating fluidized bed (CFB) system and a dual fluidized bed (DFB) system will be examined and compared systematically. For Direct Combustion of DSL in a CFB system, the high moisture of 30 wt % decreased the bottom temperature of the combustor significantly and brought in unstable Combustion, thus leading to s large amount of auxiliary fuel (such as coal) needed to raise the temperature to reach an adiabatic flame temperature and ensure normal bed Combustion. Besides, the slag formed in the loop seal also affected the stable run of the DFB Combustion system. For decoupling Combustion of DSL in a DFB system, both the temperatures in the gasifier and combustor were kept stable and a uniform temperature distribution in the combustor was also observed. In terms of gas emission, the average NO contents in a CFB system and a DFB system were about 160 ppm (369 mg/m(3)) and 50 ppm, respectively, which fully verified the property of low NO emission by decoupling Combustion. The Direct Combustion of DSL in a CFB system and decoupling Combustion in a DFB system were compared in an industrial demonstration plant for demonstrating technical features of decoupling Combustion
