The purpose of this study is to investigate the behavior of biomass gasification in the packed-bed, conducting gasification experiment and analysis of syn-gas in the reactor. In this study, pellets of black pine (ψ6.5mm×8.5mm) are fed intermittently with air as the gasification agent. The gasification experiments were carried out by two type gasification methods, such as updraft and downdraft setups. In the gasification tests, the temperature distribution in the gasification reactor and the gas compositions are measured and analyzed during gasification by thermo-couples inserted from a furnace wall and a micro gas chromatograph, respectively. Product gas before cooling were sampled for determine the amount of tar generation.

掲載種別：研究論文（学術雑誌）出版者・発行元：一般社団法人日本機械学会

This study focuses on gasification technology of carbonaceous materials in molten carbonates since this gasifier can gasify those fuels catalytically and in-situ clean up the gasified gas at high temperature simultaneously. This gasification system has such advantages that alkali metal compounds have catalytic function for the gasification reactions, the molten alkali compounds can absorb sulfur compounds and the molten media can capture ash and un-reacted particles produced. The molten carbonate employed in this study is an eutectic salt with the compositions of 43 mol% Na2CO3 and 57 mol% K2CO3. CO2 is selected as a gasification agent. Before the gasification experiments, the optimum gasification and desulfurization temperature is evaluated by the chemical equilibrium calculations. Fundamental gasification and desulfurization experiments were conducted, by using an electrically heated reactor. As a result, the main compositions of the gasified gas are CO, H2 and CH4. H2S and COS gases in the product can be absorbed almost completely by the molten alkali carbonates. These results suggest that this gasifier can gasify the carbonaceous materials and desulfurize even at high temperature inside the furnace simultaneously.

This gasification system has such advantages that alkali metal compounds show catalytic function for the gasification reactions, the molten alkali compounds can absorb sulfur compounds and the molten media can capture ash and unreacted particles produced. The molten carbonate employed in this study is an eutectic salt with the compositions of 43mol% Na_2CO_3 and 57mol% K_2CO_3. CO_2 is selected as a gasification agent. Before the gasification experiments, the optimum gasification and desulfurization temperature is evaluated by the chemical equilibrium calculations. Fundamental gasification and desulfurization experiments were conducted, by using an electrically heated reactor. As a result, the main compositions of the gasified gas are CO, H_2 and CH_4.

These results suggest that this gasifier can gasify the carbonaceous materials and desulfurize even at high temperature inside the furnace simultaneously.

To preserve fossil fuels all over the world, it is important to develop the efficient use of low rank coals like brown coal and lignite. Upgraded Brown Coal (UBC), which is the coal dewatered and stabilized in heated oil, is the promising way to use low rank coals as sophisticatedly as bituminous coals. In this paper, fundamental combustion characteristics and kinetics of UBCs are examined via thermo-gravimetric analyses. The results obtained are compared with those of some kinds of bituminous coal. The UBC seemed to have higher reactivity during combustion. There is a little difference in the volatile evolution process between the UBC and bituminous coals.

Some trace metal compounds in coal easily vaporize and form fumes during coal gasification. The fumes subsequently cause some problems such as corrosion of the gas turbine blades and material deterioration of the fuel cell. Therefore, it is necessary to understand and control the volatilization of those compounds. In this paper, the evolution behavior of trace heavy metal compounds, especially for Pb and Cd has been studied by thermodynamic equilibrium calculation under combustion and gasification conditions.

In pulverized coal fired boilers, molten ash particles generated during combustion have possibility of adhesion on surface of heat exchanger tubes. This ash deposition layer formed plays a role for insulation surrounding the tubes. In order to solve this problem, surface treatment technology of the heat exchanger tubes is developed in this study. Surface treatment technology adopted in this study could reduce the ash deposition during coal combustion. The adhesive bond between the deposition layer and the tube surface related to percentage of content of alkali sulfate in ash.
