How clean is clean enough? Maintaining thermal protective clothing under field conditions in the oil and gas sector.

The purpose of this research was to develop practical care procedures to help maintain the protective quality of flame resistant workwear laundered by workers in the field. Based on observed field conditions, experiments were conducted that simulated domestic laundry procedures. The first experiment involved two flame resistant (FR) fabrics, contaminated or not contaminated with oil. Independent variables also included detergent type and laundry pre-treatment. Other laundry parameters were controlled. Results indicated that it is easier to maintain the FR performance of the FR-treated blend than it is for the aramid fabric. It is hypothesized that energy generated by initial ignition of oil on the specimens triggers the FR mechanism of the treatment, which in turn inhibits further combustion. A second experiment using larger specimens and a domestic washing machine also supported the hypothesized mechanism.

机械活化煤气化细渣资源化利用及残碳燃烧反应动力学探究

随着我国煤气化技术的快速发展，气化渣的产生和排放量逐年增加.煤气化细渣的大量堆存，给当地的环境保护造成了巨大的压力，已经成为限制煤化工产业基地可持续发展急需解决的重大问题.本文针对气化细渣中残碳反应活性低和转化难度大的问题，研究了机械活化法对气化渣残碳反应动力学的影响.采用Coats-Redfern法分析了机械活化对残碳反应活化能的作用规律.结果表明，机械活化8 h，残碳燃烧反应活性显著提高，650℃下的活化能由63.2 k J·mol^-1降到28.4 k J·mol^-1.不添加其他化学试剂，1000℃烧制高强度轻质陶粒，其堆积密度为0.867 g·cm^-3，筒压强度为7.67 MPa.相关研究可以为我国气化细渣的资源化利用提供一定的数据和技术基础.

CFD simulation of MSW combustion and SNCR in a commercial incinerator

A CFD scheme was presented for modeling municipal solid waste (MSW) combustion in a moving-grate incinerator, including the in-bed burning of solid wastes, the out-of-bed burnout of gaseous volatiles, and the selective non-catalytic reduction (SNCR) process between urea (CO(NH₂)₂) and NO_x. The in-bed calculations provided 2-D profiles of the gas–solid temperatures and the gas species concentrations along the bed length, which were then used as inlet conditions for the out-of-bed computations. The over-bed simulations provided the profiles of incident radiation heat flux on the top of bed. A 3-dimensional benchmark simulation was conducted with a 750 t/day commercial incinerator using the present coupling scheme incorporating with a reduced SNCR reduction mechanism. Numerical tests were performed to investigate the effects of operating parameters such as injection position, injection speed and the normalized stoichiometric ratio (NSR) on the SNCR performance. The simulation results showed that the distributions of gas velocity, temperature and NO_x concentration were highly non-uniform, which made the injection position one of the most sensitive operating parameters influencing the SNCR performance of moving grate incinerators. The simulation results also showed that multi-layer injections were needed to meet the EU2000 standard, and a NSR 1.5 was suggested as a compromise of a satisfactory NO_x reduction and reasonable NH₃ slip rates. This work provided useful guides to the design and operation of SNCR process in moving-grate incinerators.
