细水雾灭油池火时各种影响因素的相对重要度分析

采用实验的方法并与理论分析相结合，对细水雾在扑灭B类火时，占主导地位的灭火机理进行了研究。实验中发现，当液体燃料的闪点相差较大时，其灭火机理往往不尽相同。并且当细水雾的雾特性相差较大时，在灭火中起主导作用的灭火机理常常也各有不同。因而那种单纯以雾滴的粒径分布作为细水雾扑灭燃料闪点较高的油池火时，雾滴的动量分布对细水雾的灭火有效性影响更大。为此，本文还建立了一个简单的模型，试图得到在这种火灾场景下，对细水雾灭火的临界动量要求。

粉煤灰净化低浓度SO2烟气试验研究

中国是一个以煤为主要燃料的国家,粉煤灰的综合利用问题早已受到人们的关注。褐煤粉煤灰中含有较多的碱性物质,它是一种优良且价廉的低浓度二氧化硫烟气脱硫吸收剂。试验研究结果表明,采用粉煤炭吸收液碱法脱硫在技术上是可行的,控制吸收液pH值大于6即可获得良好的脱硫效果。试验中考察了固液比、pH、温度、SO₂浓度和气体流墓等因素对粉煤灰吸收液净化效率的影响情况。粉煤灰碱法脱硫在经济性方面优于石灰/石灰石法。      

Life Cycle Assessment of Ultra-clean Micronized Coal Oil Water Slurry

Life cycle assessment is applied to assess the ultraclean micronized coal oil water slurry （UCMCOWS） with SimaPro and the environmental impact of UCMCOWS on its whole life cycle is also analyzed. The result shows that the consumption of energy and products are increasing along with the deepening of UCMCOWS processing, UCMCOWS making and combustion are the two periods which have a bigger impact on eco-system and human health. As a new substitute of fuel, UCMCOWS merits to be utilized more efficiently and reasonably.     

Spray optimization through application and liquid physical property variables–I

One of the most important considerations when optimizing a spray application for maximum efficacy and minimum drift is the selection of the optimum droplet size spectrum (Hewitt, A. J., 1997. The importance of droplet size in agricultural spraying. Atomization and Sprays, 7(3), 235–244). Applicators are faced with an extensive selection of nozzle types, tank mixes and adjuvants. The present paper discusses the way that the tank mix and application variables interact to produce specific spray characteristics of droplet size spectrum, coverage and performance in total spray efficiency. Experimental data investigating the effects of liquid physical properties such as dynamic surface tension, shear and extensional viscosity are described. Spray formation from emulsions, surfactants and oils is also discussed. Atomization studies conducted in wind tunnels using a wide range of atomizer and nozzle types under different operating conditions are discussed. Empirical models for predicting atomization and drift of sprays are described with emphasis on their development and practical use for spray optimization.     

Developments in application technology

Pesticides are applied in diverse situations, but in each, careful consideration has to be given to applying the optimum dosage accurately with minimal exposure of the active substance to the operator. Emphasis is given to ways in which application equipment, suitable for both small-scale and large farms has been adapted to meet health and safety requirements. New developments in nozzle design provide users with greater flexibility in optimising pesticide delivery, while minimising spray volumes. Changes in equipment design that influence dose transfer are discussed.
