In order to use the low-grade coals which are out of the power station requirement, blending of high-grade coals have been carried out in pulverized coal power station. However, for ash adhesion such as slagging and fouling, which is one of the important evaluation items of the coal, improvement of coal characteristics by the blending of coal does not become clear. It is necessary to establish the ash adhesion evaluation technology on the blending of the coal to reduce the cost of generation and increase availability of coal because most of low-grade coals are low ash fusion temperature. The purpose of this work is elucidation of ash deposition behavior at blended coal combustion. Ash deposits were collected on a heat transfer tube with an ash deposit experiment at some blend condition. In addition, we calculated the molten fraction of each blending condition by chemical equilibrium theory, using FactSage Ver.6.3.1 software.

The purpose of this study is the gasification behavior of biomass in the packed-bed, carrying out gasification experiment (updraft and downdraft gasification). In this study, pellets of black pine (φ6.5 mm × 8.5 mm) were fed intermittently and using air as the gasification agent. In the gasification tests, the temperature distribution and the gas compositions in the gasifier were measured during gasification, and the amount of tar in the gasified gas was measured. In addition, the steam was injected in the gasifier in order to reduce the amount of tar.

CO<sub>2</sub> emissions from blast furnaces should be reduced to curtail the impact of global warming. A promising solution is the low reducing agent rate (RAR) operation of blast furnaces. Char and ash particles derived from pulverized coal affect permeability in the furnace during low RAR operation. In our study, the combustion behavior and ash particle properties of pulverized coal during combustion were investigated. Char particles formed during combustion were sampled using a drop tube furnace, and then analyzed for their combustion ratio and ash particle properties. As a result, the combustion behavior of pulverized coal and properties of ash particles in raw coal were different by a coal type. Moreover, the combustibility of pulverized coal and the variation in ash particle properties during combustion were affected by the structure of the char particles.

Coal has better stability of price and supply compared to other fossil fuels. In particular, subbituminous coal is expected effective utilization because that has low cost and long minable years. However, subbituminous coal has the self-ignition risk that caused by reacting with oxygen in the air. Therefore, an objective of this study is the elucidation of oxygen adsorption properties of coal. Experimental samples are some kinds of the subbituminous coal and bituminous coal. In the oxygen adsorption experiments between 356K and 476K in 50%N_2-50%O_2 atmosphere, the amount of oxygen adsorption on the coal was determined by thermobalance. As a result, it is found that the oxygen adsorption amount of bituminous coal is larger than those of subbituminous coal and oxygen adsorption amount is correlated with the carbon content of the coal.

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.
