摘要
自1976年美国学者Rosa R.J.提出旨在减少MHD发电机用逆变器数量的合并电路概念以来,各国研究人员提出了约五类数十种合并电路,并在实验室进行模拟或在半工业装置上进行实验。但至今还未见从提高焓取出率角度设计合并电路的报道。特别在燃煤MHD发电机中渣有较大的影响。 1从高焓取出角度设计合并电路在直线型MHD发电机中,等离子体的温度和速度是三维场。
This paper discusses the criteria of selecting the electrode number in a consolidated group from the point of view of the high enthalpy extraction and the nonumiformities caused by conductive slag. A method of calculating operation consolidation voltage under high enthalpy extraction is given. An equivalent network is used to simulate the whole channel. In a slagging MHD channel, the nonuniformities in inter-electrode voltages caused by the open-gaps are predicted.
