摘要：The Original Belonio Rice Husk Gasifier (OBRHG), initially of height of 0.6 m, diameter of 0.15 m and thickness of 0.025 m was tested for biochar production through air gasification of rice husk (RH) and the design was upscaled to height of 1.65 m, diameter of 0.85 m and thickness of 0.16 m. A total of 27 experiments were conducted to monitor the gasifier performance and the system can operate with the centrifugal blower operating at a power input of 155 W and a maximum flow rate of 1450 m3/hr regulated according to the air requirement. Building the UBRHG is simple and inexpensive to fabricate and with the fairly satisfactory performance and ease of construction along with the convenience of operation, the UBRHG with RH as feed would find abundant avenues of applications in a rural setting for biochar production alongside thermal, mechanical and electrical energy delivery.

摘要：The design of a stall-regulated wind turbine to achieve a maximum annual energy output is still a formidable task for engineers. The design could be carried out using an average wind speed together with a standard statistical distribution such as a Weibull with k = 2.0. In this study a more elaborated design will be attempted by also considering the statistical bias as a design criterion. The wind data used in this study were collected from three areas of the Lamtakong weather station in Nakhonratchasima Provice, the Khaokoh weather station in Phetchaboon and the Sirindhorn dam weather station in Ubonratchathani, Thailand. The objective is to design a best aerodynamic configurations for the blade (chord, twist and pitch) using the same airfoil as that of NREL Phase VI wind turbine. Such design is carried out at a design wind speed point. Wind turbine blades were optimized for both maximum annual energy production and minimum cost of energy using a method that take into account aerodynamic and structural considerations. The work will be carried out by the program “SuWiTStat” which was developed by the authors and based on BEM Theory (Blade Element Momentum). Another side issue is the credibility of the Weibull statistic in representing the real wind measurement. This study uses a regression analysis to determine this issue.

摘要：LNG船由于货物传输时的高风险性,以及船对岸、船对船靠泊的多样性,对系泊稳定性的要求可谓是重中之重。为了不断完善系泊的设计标准,通过多年的系泊实践,以及对船员系泊经验的总结,OCIMF给出了系泊力计算时对风力,水流力,波浪等自然环境条件的选取引导,对系泊缆绳的材质,强度及断裂伸长率做出了详细对比及选取推荐,对导缆孔等系泊件强度计算时的缆绳合力包角及安全系数给出了合理性的范围指导。而在实船设计中,发现超高分子系泊缆绳HMPE和系泊件强度之间产生了一种不可调和的矛盾,确实存在极端受力下系泊件先于HMPE缆绳破损的潜在风险,进而导致缆绳及系泊件碰坏甲板设备和管路。后面分别从系泊力计算,系泊缆绳的选取,缆绳工厂拉力试验,系泊件的选取,实际系泊工况出发,得出最终结论,此风险几乎不可能出现。

摘要：在大田试验条件下,设计5个不同化肥与紫云英配比处理,连续2年在江西省丰城市研究了养分总供应量相同时紫云英NK代替等量化肥NK对水稻养分吸收及其产量的影响.结果表明:等氮钾条件下,与单施化肥相比,20%～40%紫云英氮钾替代等量化肥氮钾有利于土壤中有机质含量的提高,促进水稻地上部对氮钾的吸收与累积,从而有利于水稻产量的提高.但是,60%～80%紫云英氮钾替代化肥氮钾,水稻地上部氮钾含量和水稻产量显著下降.因此,化肥/紫云英适当配比施用有利于提高土壤有机质含量,促进水稻对氮钾养分的吸收累积,最终提高水稻产量.
