Abstract

The article presents the results of comparative investigations of operation modes of the DKVR 10-13 steam boiler system. The investigations were performed in two different modes. In the first mode, the boiler worked only on the gas fuel, whereas in the second mode, the boiler worked on the gas fuel and mazout simultaneously. Each mode requires considering the economic and ecological conditions for the combustion process for each boiler-furnace unit. The exhaust gas from mazout is discharged into the atmosphere and contains substances harmful to people and environment. These emissions can be significantly decreased by optimal control of the combustion process. Optimal organization of the process of combustion of water-mazout emulsion enables decrease in the emission of nitrogen oxides by reducing the excess air via injection of steam or water into the flame. In connection with the above, proper operation of the device must ensure a minimum possible excess of air and minimum temperature of exhaust at the boiler outlet. The experimental research has shown that special technical and technological measures should be used in relation to nitrogen oxide emission by the gas boiler. In turn, simultaneous combustion of gas and mazout allows achieving a similar value of NO\(_{x}\) emissions without need in additional measures.

中功率蒸汽锅炉同时燃烧天然气和天然气的优势的研究

摘要

本文介绍了DKVR 10-13蒸汽锅炉系统运行模式的比较研究结果。调查以两种不同的方式进行。在第一种模式下,锅炉仅处理气体燃料,而在第二种模式下,锅炉同时处理气体燃料和马苏木。每种模式都需要考虑每个锅炉炉单元燃烧过程的经济和生态条件。mazout产生的废气被排放到大气中,并含有对人体和环境有害的物质。通过最佳控制燃烧过程,可以显着减少这些排放。通过将蒸汽或水注入火焰中来减少多余的空气,使水-马蹄型乳液的燃烧过程的最佳组织能够减少氮氧化物的排放。结合以上所述,设备的正确操作必须确保尽可能少的过量空气和锅炉出口的最低排气温度。实验研究表明,应针对燃气锅炉的氮氧化物排放采​​取特殊的技术措施。反过来,气体和麦芽酒的同时燃烧可以实现类似的NO值 实验研究表明,应针对燃气锅炉的氮氧化物排放采​​取特殊的技术措施。反过来,气体和麦芽酒的同时燃烧可以实现类似的NO值 实验研究表明,应针对燃气锅炉的氮氧化物排放采​​取特殊的技术措施。反过来,气体和麦芽酒的同时燃烧可以实现类似的NO值\(_ {x} \) 排放,无需采取其他措施。
