Nitzschia ZJU1, which originated from the diatom Nitzschia sp. (ash free dry weight of biomass was 0.12 g L−1 and its lipid content was 13.34 %) after 60Co-γ ray irradiation and domestication at high-salinity, was re-mutated by 137Cs-γ irradiation to increase lipid productivity. The lipid yields of the new mutants Nitzschia ZJU2 and Nitzschia ZJU3, which(More)
This study developed a new model for the low NOxignition for the direct flow of pulverized coal, which enabled the influence of the primary air and internally recirculated flue gas (RFG) on NOx formation to be investigated. A model of the preignition zone was discussed in detail. Three new parameters, the Local Stoichiometric Ratio of Volatiles(LSRV), the(More)
This study developed a new model of low NOx combustion for the direct flow of pulverized coal, which enabled the relationships among gas temperature, oxygen concentration, time consumption, and distance to be investigated. A model of the ignition and combustion zone was discussed in detail. It was shown that the gas temperature and the oxygen concentration(More)
In this study, a thin-layer solar drying experiment was conducted outdoors to investigate characteristics of solar drying of lignite. The maximum temperature of lignite in the solar dryer reached 87 in 140 minutes when the hourly average of solar radiation intensity was about 950 W/m2. Meanwhile the moisture content of lignite was reduced to 1.38 %(More)
