[目的]文章主旨为满足国家对火力发电厂烟气污染物排放"超洁净"排放指标的要求。[方法]通过对广东某火力发电厂除尘和脱硫技术进行研究,提出了高效脱硫及除尘一体化超洁净技术,并在该电厂顺利应用。在常规烟尘和SO_2脱除方案上的基础上,通过对已有除尘和脱硫设备进行一体化设计和优化,并增加MGGH装置和电除尘除雾装置,协同对污染物包括烟尘和SO_2进行脱除,并提高烟囱出口烟气温度,减少烟气中液滴和烟尘浓度。[结果]机组投运后,实测烟囱出口烟尘和SO_2排放浓度为2.2 mg/Nm~3和16.7 mg/Nm~3,满足并优于火力发电厂"超洁净"排放的要求,且消除了烟囱出口的"石膏雨"现象。[结论]应用该项技术,可以在不设置湿式除尘器的条件下即可满足"超洁净"的排放要求,对新建或改造项目有很好的指导和借鉴意义。 相似文献

The issues related to the reliability of hydrogen engines of unmanned vehicles and increasing the efficiency of using hydrogen as fuel when using the method of its production during the decomposition of hydrogen-containing molecules of liquid-phase organic compounds in a plasma discharge under the action of intense ultrasonic exposure are considered. Experiments have shown that as a result of decomposition in the acoustoplasma discharge of liquid hydrocarbons, solid-phase carbon-containing products are formed, chemical transformations occur in the liquid phase and hydrogen-containing combustible gas is formed. Hydrogen-containing gas can be used as fuel immediately after synthesis, i.e. it does not require separation, since in addition to hydrogen it contains only impurities of CO2 and water vapor. The purpose of the study is to formalize the basic conditions for tightening the control of mutual compliance with the efficiency of hydrogen engines of the same series in the conditions of their mass production. Methods of mathematical statistics and hardware-software modeling were used in the study. The term “unerroric of quality mutual compliance control” is introduced to describe a set of hardware and software tools for such control. The principle of in-depth testing of the technical condition of such engines of one series is described in a multidimensional formulation of the quality control problem for three of their operating parameters at once. The conditions for increasing the mutual correspondence of the measured values of such parameters in the conditions of serial production of hydrogen engines are formalized. 相似文献

世界发电燃料结构在不断的转换过程中。18世纪60年代从薪柴转到煤炭,19世纪到20世纪初大量发展燃煤电厂;20世纪20年代又从煤炭转向石油和天然气,20年代上半叶又大量发展燃油电厂;20世纪末由于天然气生产的发展,天然气因环境影响小,受到工业发达国家的青睐,加速发展天然气电厂。我国70年代初和90年代曾两次发展燃油电厂,由于石油危机和石油价格暴涨而受到制约,不得不实行以煤代油,改造燃油电厂。现在似乎认为燃油电厂不能再搞,但又出现发展燃气电厂的热流,发展燃气电厂确实是当今的世界潮流,但是同当年发展燃油电厂一样,要研究是否符合中国的国情? 相似文献

The daily chronological variation of the solar heat gain through fenestration was studied for different orientations, locations, and months. Then, a method was presented to estimate the alleviation of the solar load achievable by external shading.This method was applied to investigate the effect of external shading for different exposures. The two indices, “Effectiveness” and “Efficiency”, were introduced to describe the theoretically possible solar load reduction.The feasibility of external shading, as a means of lowering the cooling load, was assessed on different exposures and at different latitudes. The assessment was based on two counterweighing criteria. These are the actually gained saving in the cooling load and the size of the required shading device. 相似文献

为适应建筑业可持续发展的需要,提出了对投标方进行施工绿色性预评价的观点,即通过分析招标控制价(或标底)和投标报价,计算出投标方施工节约资源能源的预算费用值,利用该值可进行资源能源消耗预评价;同时,通过分析投标技术资料判断其施工环境保护措施的合理性、有效性,进而对施工环境影响进行打分评价,借助于建筑安装工程费中的环境保护费,可将打分转换为施工环境保护的费用当量值,利用该值可进行环境影响预评价;将两种费用值相加即可得到施工绿色性费用当量值,利用该值可实现对施工资源能源消耗和环境影响的统一评价,有助于选择绿色施工水平较高的承包商. 相似文献
