ジャーナル フリーA MHD electric power generation has the potential capability of increasing the conversion efficiency up to 50% with the conventional steam turbin generator. In addition, MHD generator has a great advantage of the polution protection, because MHD-steam tubine genetation has itself the desulfurization process
In Japan, the profect of the research and development on MHD power genra tion started in 1966, under the auspices of the Agency of Industrial Science and Tech nology, Ministry of International Trade and Industry.
Under the present project emphasis has been placed on investigations about the output characteuristics of the generating channel and enhancement of duration concerning to various components of MHD system. In particular, efforts were directed toward high resistance to errosion of electrodes due to the arching phenemena and heat of gas. In addition, the great emphaesis were placed to the seed depositon and attachment to the walls of heat exchangers of MHD system.抄録全体を表示PDF形式でダウンロード (1133K) -

ジャーナル フリーSince the energy crisis in the fall, 1973, the use of coal resources has been considered as the effective energy source from the standpoint of national energy security.
Usually the coal fired boilers have more environmental impacts than the oil/gas fired ones, so we need new technical process which has the least environmental impacts. The two types of new process are considered.
The first one is the SOx/NOx removal process from the stack gas of the conventional coal fired boilers.
The second one, the subject of this paper, is the integrated gas/steam combined cycle system with coal gasification, which has now being developed in USA, Europe and Japan.
At present, this intergrated coal gasifier combined cycle system is not economical in comparison with conventional boiler because of its low efficiency.
But in near future, it is expected that this new system will be the most economical one and have the least environmental effect. In order to realize this new system, there are three major keys which must be developed, the advanced type coal gasifier, the hot gas clean up technique and the new type of gas turbine with high inlet gas temperature 1, 300°C above.抄録全体を表示PDF形式でダウンロード (1852K) -

ジャーナル フリーHydrogen is considered as a very Promising material for the future energy system. When hydrogen is used as an energy carrier, hydrogen will be used as fuel gas for the burners in the industry and also in the houses. Therefore, it is important to discuss the problems about the combustion of hydrogen as a practical fuel.
In this paper, the concerning literatures are reviewed and the basic characteristics of hydrogen combustion are discussed.抄録全体を表示PDF形式でダウンロード (1798K) -

ジャーナル フリーKinetics of the reaction of the sulfur dioxide with calcined limestone were discussed in this paper. From an analysis of mass transfers in this reaction, next conclusions were obtained;
(1) Diffusion of sulfur dioxide through gas film boundary layer on the calcined limestone particle was considered not to be the rate controlling resistance.
(2) From the characteristics of sulfur dioxide transfer into various paricle size of calcined limestone particles. The rate controlling resistance was considerded to be as follows;
(a) The chemical reaction of sulfur dioxide with calcined limestone in the particles is the rate controlling step when the limestones having the particle size of under several microns are used.
(b) Sulfur dioxide diffusion into the particles is the rate controlling step when the limestones having the particle size of above 20 microns are used.
(c) Boeh steps of chemical reaction and sulfur dioxide diffusion in the particles controll the rate when the limestones having particle size from several to 20 microns are used.
(3) Sulfur dioxide diffusion are considered to be rate controlling resistance in the proceeding reactions, because of the decrease in both of pore volume and surface area in the particles.抄録全体を表示PDF形式でダウンロード (809K) -

ジャーナル フリーEffects of SO2 and H2O on NO oxidation has been investigated in the presence of Cr, Co, Mn, Ni, Cu, Fe oxides or Pt, Ag metals supported on γ -alumina . The extent of NO oxidation decreases gradually by addition of SO2 and H2O. However, the original conversion of NO is obtained when they are removed from the reaction system.
NO adsorbs strongly on Mn-almina catalyst in the presence of O2. When SO2 or H2O is injected into the reaction system by a pulse technique, they expell the adsorbed NO and NO2 from the surface of the catalyst. SO2 reduces remarkably the amount of NO adsorbed.抄録全体を表示PDF形式でダウンロード (704K) -
