23. Homogeneous Reaction Behaviors of Mercury Compounds

KAMESHIMA Tamotsu, YAO Hong, NARUSE Ichiro

Proceedings of Conference on Coal Science Vol. 42 ( 0 ) page： 49 - 50 2005

Publishing type：Research paper (scientific journal) Publisher：The Japan Institute of Energy

The objectives are to elucidate homogeneous mechanisms of mercury oxidization and study the important factors on mercury oxidization in the homogeneous reaction system. The mercury oxidation experiments were conducted by injecting Hg gas with HCl or Cl_2 gas, using an electrically heated horizontal tube. Chemical equilibrium and chemical kinetics analyses were also carried out to study the main mercury elementary reaction scheme theoretically. The results show that HCI has little possibility of mercury oxidization. For Cl_2 addition, however, the mercury oxidization is enhanced more. The coexistence atmosphere of H_2O with Cl_2 affects promotion of mercury oxidization.

218 Scenario making for effective utilization system of woody biomass in local community At Shinshiro and Horai areas in Aichi Prefecture

Publishing type：Research paper (scientific journal) Publisher：The Japan Society of Mechanical Engineers

In this study, Shinshiro and Horai areas were selected as a local community with forest resources unused effectively since fraction of forest area in this community exceeded to 60%. First, tree types and their amount were investigated in those areas. Amount and types of recycled and wasted woody biomass were also investigated by hearing and questionnaires to sawmill factories in Shinshiro and Horai areas. Based on those investigation results, available amount of woody biomass to energy and material resources was estimated. Additionally, several energy production technologies such as combustion, gasification and so forth were also surveyed Consequently, a small-scale fixed bed gasifier with a gasoline engine was selected as one of the candidate. To operate this gasifier, fundamental thermal properties of the biomass selected were analyzed, and the gasification and power generation experiments were also conducted.

12. Ash Behaviors and Deposition Characteristic in Coal Gasification Process

Kawai Takayuki, Miyauchi Yoshiki, Naruse Ichiro

Proceedings of Conference on Coal Science Vol. 42 ( 0 ) page： 27 - 28 2005

Publishing type：Research paper (scientific journal) Publisher：The Japan Institute of Energy

Recently, high-temperature and high-pressure coal gasification combined cycle systems have been under developed to realize more efficient and ecological coal utilization technologies. In the gasification process, however, slugging and fouling troubles sometimes occur in the section of furnace wall and heat exchanger, respectively, since the operating temperature exceeds the ash melting temperature. Therefore, it is necessary to predict ash behaviors in the gasification process, based on the properties of mineral particles in the raw coals. Objective of this study is to elucidate the formation behaviors of ash particles and deposition characteristic during coal gasification. The experiments were conducted, using a horizontal high-temperature pulverized coal reactor. Ash particles in the reacting particles sampled during reaction were analyzed, using a Computer Controlled Scanning Electron Microscope (CCSEM).

39. Fundamental experiments of coal and biomass gasification in molten carbonate

IWASAKI Shin, NARUSE Ichiro

Proceedings of Conference on Coal Science Vol. 41 ( 0 ) page： 83 - 84 2004

Publishing type：Research paper (scientific journal) Publisher：The Japan Institute of Energy

Gasification technology of solid fuels in molten carbonates has been selected as one of the advanced gasification systems. The molten carbonates employed in this study are eutectic salts of Na_2CO_3 (43mol%) and K_2CO_3 (57mol%). As the advantages of utilization of the eutectic salts for coal gasification, the alkali metals play a role for the gasification catalyst, desulfurization solvent and capture material of ash particles. The gasification test results show that the main compositions in the product gas are CO and H_2. H_2S and COS concentrations in the product gas is low enough to introduce the gasified gas into an Molten Carbonate Fuel Cell (MCFC) system, in which H_2S and COS concentrations should be less than 1ppm in the gasified gas.

Co-combustion technologies of coal with biomass have been applied in several practical coal boilers in order to reduce CO2 emission, fuel cost and so forth. Furthermore, the biomass may be able to enhance the combustion performance and to control NOx emission, since the biomass contains high volatile matter and evolves NH3 as volatile-N species. Emission of NOx from coal combustion has recently become a subject of intense research, because of its increasing concentrations in the atmosphere and its known ability to deplete the ozone layer and also contribute to the Greenhouse effect. However, fundamental combustion and NOx emission characteristics for biomass and mixtures of coal with biomass have not been elucidated precisely yet. From these viewpoints, co-combustion technology is one of the candidates to reduce the NOx emission and enhance the effective utilization of both low-grade coals and biomasses. In this study, fundamentals of pyrolysis characteristics of several types of biomass were studied first, using a thermo-gravimetric analyzer. The combustion behaviour of biomass, coal and its mixture were tested, using electrically heated drop tube furnace. In the combustion test, the ignition behaviour, Combustion efficiency and NOx (NO and N2O) emission behaviour were focused, based on the results of gas compositions along the furnace axis. The main results obtained show that biomass can enhance the ignition characteristics of the low-volatile coal during co-combustion. NO and N2O formation during the co-combustion affects effect of coal combustion even if the input fuel nitrogen becomes half of that under coal combustion condition. At least NO behavior can be simulated by the homogeneous reaction scheme relating to NOx even at constant temperature. During biomass combustion, fine particulates less than 2 µm are produced as ash particles. Burning biomass with coal shifts the particle size distribution from fine particles to coarse particles.
