摘要： According to the apparatus and method, combustible gas having a stable composition can be formed even if the load is charged. Burners are provided in the upper and the lower regions of an entrained bed coal gasification reactor. The temperature of the product gas is kept low in the upper region and high in the lower region. The volumes of the upper and lower regions are changed to meet the load so that the rate of heat loss becomes constant even if the load changes. Since the rate of heat loss can be kept constant and consequently variation of the composition of the product gas can be suppressed small, the efficiency of the coal gasification electric power generating system can be kept constant.

摘要： The invention is to continuously measure the contents of trace ingredients such as alkaline metal contained in combustion gas with high precision. An oxidizer and fuel are supplied into a flue line to form a flame, while a part of the combustion gas is introduced to the flame for inducing light emission. The contents of metal ingredients in the gas are calculated based on the intensity of the emitted light. Since a flame forming device is installed in the flue line without any additional equipment such as a sampling line, and such the contents of trace ingredients in the gas are calculated based on the intensity of the emitted light, the contents of the trace ingredients can be measured with high precision. Quickly responsive monitoring and control are assured.

摘要： The present invention provides a desulfurizing agent comprising a porous oxide carrier, at least one of molybdenum oxide and tungsten oxide as a first component, supported on the carrier, and at least one of manganese oxide, cobalt oxide and nickel oxide as a second component, supported mainly on the surface of the first component. In a coal gasification system using the present desulfurizing agent and a power generation system using the purified gas therefrom, a reduction column for converting a portion of sulfur dioxide in the regenerated gas to hydrogen sulfide as a pretreatment means to a Claus reaction column can be eliminated when the desulfurizing agent is regenerated. Furthermore, in the present invention a desulfurizing agent capable of reacting with hydrogen sulfide to form a solid sulfur compound at a high temperature is supplied to a gasification furnace and the resulting sulfur compound is withdrawn from the gasification furnace as molten slag together with ashes of fine coal powder, where desulfurization can be attained without a Claus reaction column and without a reduction column. Such desulfurization is likewise applicable to a coal gasification system and a power generation system based on the coal gasification.

摘要： A heat conducting member is placed in the space between a semiconductor chip which generates heat and a heat transfer block which is cooled by a coolant, and the heat conducting member conducts heat from the semiconductor chip to the heat transfer block. The heat conducting member has a slanted surface which is inclined with respect to a surface to be cooled of the corresponding semiconductor chip. Even when the semiconductor chip is displaced or inclined with respect to the heat transfer block, the whole of the cooling surface of the semiconductor chip can be kept in contact with the corresponding heat conducting member.
