Maximum power densities 40 mW·cm-2 and 130 mW·cm-2 for the PEN configuration with a Mo-Ni-S-based composite anode, nano-composite electrolyte (Li2SO4+Al2O3) film and a NiO-based composite cathode were achieved at 600°C and 680°C, respectively.
This paper introduces the results of calculation of the combined cycle efficiency for large-scale MHD-steam power generation which uses mazout and coal respectively as fuels.The difficulties of burning coal are discussed.Results of calculation are compared with the corresponding calculation from abroad, and it is pointed out that the combined cycle efficiency of MHD-steam generation exceeds 50% in all cases, for stations in the order of thousands of MW using preheated air as oxidizer.Thus, MHD generat...
The article describes some experimental investigations of improving 200 MW steam turbine reliability in Dong Fang steam turbine works, such as HP cylinder, blading, valve stem, bearing and oil system (oil reservoir, oil level indicator, rotor jacking pump etc.), control system and protection devices, and turbine associated auxiliaries.
In this paper the boiler DG 670/140 for 200 MW power units made in Dongfang Boiler Works is described. Two versions of boilers, oil fired or coal fired, are supplied. Oil fired boilers have been put into operation for five years already. The main operating performances have been found to fulfil the design requirements quite well. Tangential firing, dampers regulation of reheat steam temperature by dampers and membrane-walls are adopted in the coal fired boilers. Boilers of this type are designed to bu...
