Ash deposition behaviors on heat transfer tubes under blended coal combustion condition have been becoming one of important issues associated to recent pulverized coal-fired boilers. In this study, ash deposition experiments, using two ash samples from bituminous and subbituminous coals, at two different temperatures, 1050℃ and 1250℃, were carried out and the mass of ash deposition was measured. Deposited ash samples were solidified by epoxy resin, and then analyzed by Scanning Electron Microscope (SEM) and Energy Dispersive X-ray spectrometer (EDX). In addition, fractions of liquid slag in ash were estimated by Thermo-equilibrium calculation to analyze ash melting characteristics.

Some ash particles of biomass fuels adhere to heat exchanger tube surfaces, which causes some troubles such as heat transfer inhibition, operational problems and hot corrosion in incineration plants. In this study, the authors have developed a surface treatment technology of tubes via a thermal spraying technology and a corrosion-resistant coating to reduce the ash deposition and the hot corrosion. Both the results of 'High-temperature Corrosion Test' and 'Electrochemical Impedance Spectroscopy (EIS)' are exhibited in this paper. The major conclusions are drawn as follows: Polarization conductance of specimens can be evaluated by means of equivalent circuits which are assumed on the interface between specimens and simulated ash. Moreover, it is clear that EIS is available for evaluating the corrosion resistance.

Currently, one methods of recycling waste plastics include gasification. Gasification is carrying out thermal decomposition of the carbon resources, such as coal and the biomass for generating combustible gas. However, gasification will generate tar which is a mixture of polycyclic aromatic hydrocarbon. It generate as a by-product. If the amount of generation of tar can be reduced, failure of a gas engine can be prevented, and also generation gas can also be increased. So, in this research, by adding vapor as a gasifying agent, when gasifying a plastic, reduction of tar was aimed at and the gasification behavior was inquired using the Time of Flight Mass Spectrometry (TOFMS).

Some ash particles of solid fuels adhere to heat exchanger tube surfaces, which causes some troubles such as heat transfer inhibition, operational problems and hot corrosion in incineration plants. The authors have developed a surface treatment technology of tubes via a thermal spraying technique (TST) to reduce the ash deposition. Both the results of 'High-temperature corrosion test' and 'Alternating current impedance testing' were exhibited in this paper. The corrosion resistance of TST was evaluated by measuring the polarization conductance and weight loss in corrosive conditions. As a result, it was clear that some materials of TST have high corrosion resistance and the AC impedance testing is available for evaluating the corrosion resistance.

The price of caking coal, which is used in the production of metallurgical coke, has risen in recent years. Also of concern is the amount of CO2 emitted from steel industries, comprising approximately 15% of total CO2 emissions in Japan. Therefore, CO2 emissions from the ironmaking process should be reduced to avoid global warming. In this work, fundamental research is conducted on the effect of adding woody biomass to the properties of coke, with the aim of possibly using woody biomass, which is carbon neutral, as a raw material in coke-making. Experimental results showed that the connectivity between coal particles in the coke sample during carbonization and coke strength drastically decrease by adding woody biomass to caking coal. However, the coke properties of the coke sample with added woody biomass could be improved by removing the partly volatile matter of woody biomass before mixing with caking coal, and as a result, the possibility of using woody biomass as a raw material for coke-making with prior carbonization at temperatures of more than 500°C was found.
