In pulverized coal combustion boiler, ash deposits such as slagging and fouling prevent heat transfer. On the other hand, a reserve of high lank coal is limited. So co-combustion of low lank coal, that is inexpensive, and high lank coal has been carried out in pulverized coal combustion boiler. Generally, low lank coal includes ash of low melting point. However, in this situation, ash deposition behavior has not been clarified. The purpose of this work is elucidation of ash deposition behavior during co-combustion in pulverized coal combustion boiler. Ash deposits were collected on a heat transfer tube with an ash deposit experiment at some blend condition. Ash particles near the adhesion interface were analyzed about element distribution by a Scanning Electron Microscope and an Energy Dispersive X-ray (SEM/EDX). And ash particles are also analyzed about composition and particle size distribution by a Computer Control Scanning Electron Microscope (CCSEM). We calculated the molten fraction of each mix condition ash by chemical equilibrium theory, using FactSage Ver.6.3.1 software.

Recently, oxy-fuel coal combustion has drawn attention as useful technique to achieve carbon dioxide capture and storage (CCS). This is the technique that enriches CO_2 in exhaust gas by the flue gas recirculation with additional pure O_2 to combustion atmosphere, which makes easy to capture CO_2. 0n the other hand, bubbling fluidized bed coal combustion has advantages of direct sulfur capturing in furnace by adding desulfurizing agents to bed material and decreasing of thermal NO_x as a result of low combustion temperature. However, oxy-fuel combustion behavior of coal in a bubbling fluidized bed is still unclear. In this study, we conducted the coal burning experiment under CO_2/O_2 using bubbling fluidized bed and compared oxy-fuel combustion behavior with air combustion behavior of coal. In addition, three coal samples having different nitrogen contents were tested to estimate the effect of raw coal properties on oxy-fuel combustion behaviors.

In general, the use of coal having different physical properties from those of design coal in a pulverized coal combustion plant causes ash deposit troubles, such as fouling and slagging. However, from the viewpoint of utilization of low rank coals, flexibilities for various coal types as fuel are going to be required in pulverized coal fired boilers before long. Then, it is important to preliminarily predict mineral particle behaviors in coal combustion process. In this study, their behaviors are studied by use of artificial coal samples which contains included minerals and excluded minerals. Coal samples are burned in a drop tube furnace to sample particles in different conversion ratio and residence time. Then included and excluded minerals are analyzed and classified in particles by CCSEM

ホウ素化合物は一般的に揮発性が高いので，石炭燃焼排ガス中では，その一部がガス相へ移行する．しかし，ガス相への移行割合は炭種に依存し，その挙動は複雑である．よって，石炭燃焼場におけるホウ素の挙動を正確に解明するためには，ガス状ホウ素を高精度に測定する必要があり，本報では，石炭燃焼場を対象としたガス状ホウ素の測定法を開発した．実験は，ガス状ホウ素発生装置を試作し，模擬石炭燃焼排ガスや実際の石炭燃焼排ガスを用いて，吸収液の選定，配管材料などのサンプリング条件の最適化，ならびに確立した測定法の精度確認を行った．主な結果として，ガス状ホウ素の測定に最適な吸収液は硝酸酸性の過酸化水素水であり，また，ステンレス製のプローブやアルミナバインダを含むシリカ製フィルタ紙はガス状ホウ素を吸着するため，サンプリング流路や吸収液用のインピンジャーの最適な材質は石英ガラスあるいは四ふっ化エチレン樹脂であることならびにサンプリング流路は130℃以上に保温することにより高精度な測定が可能であることなどを明らかにした．

Coal and solid fuels derived from industrial wastes sometimes contain a small amount of mercury compounds. In conmbustion processes, gaseous elemental mercury passes through the stack and releases into the atmosphere. Mercury emissions in the combustion processes have been focused as one of upcoming air pollutants. In this work, it is the purpose to use wastes (sewage sludge, woody biomass and municipal waste) as an adsorbent of elemental mercury. We conducted mercury adsorption experiment used carbonized sewage sludge, carbonized biomass and carbonized municipal waste as adsorbents. As a result, the mercury adsorption ratio of carbonized municipal waste was the largest.

Currently, it becomes increasingly necessary to decrease CO_2 emissions from fossil fuel combustion processes, because they are major contributors to the global warming. Oxy-fuel coal combustion has drawn attention as useful technique to achieve carbon dioxide capture and storage (CCS). This is the technique that enriches CO_2 in exhaust gas by the flue gas recirculation with additional pure O_2 to combustion atmosphere, which makes easy to capture and liquidize CO_2 downstream. However, there have been few reports about behaviors of various environmental pollutants in oxy-fuel coal combustion with the flue gas recirculation. In this study, we experimentally estimated effects of NO and N_2O recirculation with CO_2 by a drop tube furnace equipment. In addition, we simulated NO and N_2O formations under oxy-fuel coal combustion condition by elementary reaction analysis, and then we discussed mechanism for the formation of NOX.
