Mixed incineration of municipal solid waste (MSW) in existing coal gangue power plant is a potentially highefficiency and low-cost MSW disposal way. In this paper, the co-combustion and pollutants emission characteristic of MSW and coal gangue was investigated in a circulating fluidized bed (CFB) combustor. The effect of MSW blend ratio, bed temperature and excess air ratio was detailedly studied. The results show the NOX and HC1 emission increases with the increasing MSW blend ratio and the SO2 emission decreases. With the increase of bed temperature, the CO emission decreases while the NOX and SO2 emission increases. The HC1 emission is nearly stable in the temperature range of 850-950℃. The increase of excess air ratio gradually increases the NOX emission but has no significant effect on the SO2 emission. The HC1 emission firstly increases and then decreases with the increase of excess air ratio. For a typical CFB operating condition with excess air ratio of 1.4, bed temperature of 900℃ and MSW blend ratio of 10%, the original CO, NOX, SO2 and HC1 emissions are 52, 181, 3373 and 58 mg/Nm^3 respectively.

A two-factor(23)orthogonal testwas conducted to investigate the effects of dietary myo-inositol(MI)on the osmoregulation and carbohydrate metabolism of euryhaline fish tilapia(Oreochromis niloticus)under sustained hypertonic stress(20 practical salinity units[psu]).6 diets containing either normal carbohydrate(NC,30%)or high carbohydrate(HC,45%)levels,with 3 levels(0,400 and 1,200 mg/kg diet)of MI,respectively,were fed to 540 fish under 20 psu for 8 *** MI supplementation significantly improved growth performance and crude protein content of whole fish,and decreased the content of crude lipid of whole fish(P<0.05).Curled,disordered gill lamella and cracked gill filament cartilage were observed in the gill of fish fed diets without MI *** ion transport capacity in gill was significantly improved in the 1,200 mg/kg MI supplementation groups compared with the 0 mg/kg MI groups(P<0.05).Moreover,the contents of Na^(+),K^(+),Cl^(-)in serum weremarkedly reduced with the dietary MI supplementation(P<0.05).The fish fed 1,200 mg/kg MI supplementation had the highest MI content in the gills and the lowest MI content in the serum(P<0.05).Additionally,the fish fed with 1,200 mg/kg MI supplementation had the highest MI synthesis capacity in gills and brain(P<0.05).Dietary MI markedly promoted the ability of carbohydrate metabolism in liver(P<0.05).Moreover,fish in the 1,200 mg/kg MI groups had the highest antioxidant capacity(P<0.05).This study indicated that high dietary carbohydrate would intensify stress,and impair the ability of osmoregulation in tilapia under a long-term hypersaline *** supplementation of MI at 1,200 mg/kg in the high carbohydrate diet could promote carbohydrate utilization and improve the osmoregulation capacity of tilapia under long-term hypertonic stress.

In this study, a programmable freezing technique has been developed for strip spawned sperm in the blue mussel, M ytilus galloprovincialis. The optimized key parameters include cooling rate, endpoint temperature, thawing temperature, sugar addition and sperm to oocyte ratio. The sperm quality was assessed by the fertilization rate or the integrity of sperm component and organelle. The highest post-thaw sperm fertilization rate was 91%, which was produced with sperm cryopreserved in 8% dimethyl sulfoxide at the cooling rate of-4°C/min from 2°C to-30°C before being plunged into liquid nitrogen for at least 12 h, thawed in a 20°C seawater bath and fertilized at sperm to egg ratio of 50 000:1. The addition of glucose, sucrose or trehalose to 8% dimethyl sulfoxide could not further improve fertilization rates. The fluorescent assessments showed that the post-thaw sperm plasma membrane integrity and acrosome integrity were significantly damaged in comparison with fresh sperm.

集成了风电等分布式电源和储能系统的配电网称为有源配电网。为了提高考虑风电随机性的有源配电网可靠性评估的计算效率,同时最大程度地拟合风电出力的随机性特点,建立了基于拉丁超立方抽样和场景削减技术的风电可靠性评估模型,并提出一种系统化的有源配电网可靠性评估方法。对于有源配电网,主网发生故障后,配电网的部分可以形成微电网孤网运行。当处于微电网运行状态时,考虑在每一种风电功率场景下,微电网内负荷和发电是否均衡,并在发电不足时执行切负荷策略,得到了微电网内负荷点被切除的概率,然后基于孤岛形成概率,运用全概率公式得到了配电网负荷点的可靠性指标和系统的可靠性指标,并在改进的IEEE RBTS算例系统上进行仿真。该算法能够综合考虑风电可靠性模型的计算效率和准确性2个方面,算例结果表明,风机加入配电网能够有效提高相应微电网的可靠性水平。

在国内外相关研究的基础上,对木灰这类典型生物质灰的组成和物理、化学特性进行分析,并阐述了木灰作为肥料施用后对作物、土壤表层植被、土壤微生物群和环境各方面的影响。木灰的K含量不高,但是具有较高的pH值,对酸性土壤的改良作用很明显。pH值的提高可以改变土壤中微生物结构,促进微生物的活动,增加土壤肥力。同时,木灰还具有大量元素富集的特点,施用后会改变土壤中元素的构成,增加土壤中N、K等植物生长必需元素的可利用量,从而促进作物的生长。根据目前研究情况,木灰肥用不但实现了元素循环,而且一定程度上提高和改良了土壤特性。

通过对稻秆原料进行常规特性分析和EDX元素含量分析,发现钾在稻秆无机元素中占有重要地位。参考原料化学分馏法和土壤中钾的分类与测试方法,给出了对生物质原料及其燃烧产物中钾的定性与定量简易方法。通过程序控温型固定床对稻秆先进行缓慢氧化,然后以100℃为间隔从400～900℃进行成灰,并分别测试其成灰率、有效钾和全钾的份额。结合稻秆原料及其灰中钾的份额分析,进行了稻秆灰中有效钾转化与释放的计算,发现有效钾在700～800℃之间有快速的释放和形态转变。稻秆灰的XRD分析结果表明秸秆灰中钾主要以KCl、K_2SO_4形式存在,得到了钾以盐的形式进行转化与释放的机理。该文中燃烧温度对钾转化与释放的影响规律对设计秸秆电厂时的炉型选择和燃烧参数确定有一定参考价值。

在小型燃煤鼓泡流化床上对稻秆低温燃烧的聚团现象进行了试验研究并对其机理进行了探讨。对所取床料样品的分析结果表明,床料中碱金属主要以钾并以KCl和K_2SO_4水溶性钾方式存在,且随着燃烧时间的增长碱金属在床料中呈增加趋势,同时床料聚团颗粒增多。对稻秆在650℃和700℃成灰的XRD检测也表明,稻秆在该温度范围内燃烧后灰的物相主要是KCl、K_2SO_4和SiO_2,而KCl和K_2SO_4的两相低温共熔温度约为684℃.说明KCl和K_2SO_4低温共溶对稻秆低温燃烧床料聚团具有重要作用。

为了探索碱金属在秸秆流态化燃烧中的迁徙转化规律,在0.5MWt规模的循环流化床试验台上以稻秆为原料进行了燃烧温度较低的正常工况和作为对照的高温工况燃烧试验,试验中对各工况床料取样并进行测试分析。研究发现秸秆原料中的可溶性钾在正常工况下可部分以水溶性钾盐的形式包覆在床料颗粒表面,质地疏松,易于剥落;而高温工况中床料颗粒表面的含钾物质性质发生变化,可溶性钾盐存在相当程度的气相挥发和向复杂硅酸盐转化的趋势,形成的附着物致密光滑,呈局部熔融状态。试验表明燃烧温度对碱金属物质在床料表面迁徙转化影响显著,燃烧温度关系到流化床中能否顺利进行秸秆的持续燃烧。
