The equipment installing engineering company of taiyuan iron & steel construction corporation takes in hand technique rebuilding and overhauling engineering from taiyuan iron & steel co . ltd . we did n ' t do systemic analysis and quantitative research about the rinsing to steel piping of hydraulic pressure . it was localized in experience at local operation . we settled for the actual method and efficiency of rinsing because we did n ' t realize the graveness of the oil pollution 太钢建设设备安装公司承担着太钢大部分技术改造和检修工程，在过去对液压钢管的冲洗没有进行过系统分析和定量的研究，现场操作局限于经验，冲洗方法和冲洗效率多少年来满足于现状，其主要的原因还是对液压油液污染危害的严重性和对其控制手段认识的不够。
Ash deposition on boiler heat exchanger surface is a common phenomenon in fossile fuel powered power plant . this paper focuses on the research building a suitable model of soot deposition status of heat exchanger surface , and constructs a online monitoring system based on the built models . this will provide a reliable foundation to the optimal scheduling of the soot blowers 本文针对锅炉受热面灰污染危害严重的普遍现象，以北仑电厂600mw1 #锅炉作为研究对象，进行了有关电站锅炉受热面灰污染在线监测的研究工作，为吹灰优化经济运行提供了可靠的依据。
Article 56 units that have caused severe environmental pollution by hazardous waste due to accident or other unexpected events must immediately take measures to eliminate or reduce the danger and damage of environmental pollution , promptly inform the units and residents that may be harmed by the pollution , in the meantime , report to the competent administrative department of environmental protection of the local people ' s government at or above the county level and other relevant departments , and be ready for investigation and settlement of the matter 第五十六条因发生事故或者其他突发性事件，造成危险废物严重污染环境的单位，必须立即采取措施消除或者减轻对环境的污染危害，及时通报可能受到污染危害的单位和居民，并向所在地县级以上地方人民政府环境保护行政主管部门和有关部门报告，接受调查处理。
Seg l = en - us > in case of the real limitations given by the objective circumstances where the noise pollution from air - conditioning equipment can not be eliminated for the time being , care must be taken to minimize the harm caused by noise pollution and a written agreement shall be reached through consultation with the affected units or individual persons 确因客观条件所限，暂时不能通过治理消除空调设备噪声污染的，必须把噪声污染危害减少到最低程度，并与受污染的单位和个人协商，达成书面协议。
Subsequently , we introduce some monitoring model and implement currently used , then we release our model , which suit the 1 # boiler of beilun power plant , on the basis of the models before . our model is subdivided into three categories , each category suit the heat exchanger of deferent type : the furnace , convective surface and trisector air preheater , all these categories use clean factor as the indication of the soot desposition level 首先介绍了锅炉灰污染危害的现状，对比研究了国内外的灰污染监测手段和监测模型，并针对北仑1 #锅炉，建立了锅炉各受热面灰污染监测模型，这些监测模型分为炉膛、对流受热面、以及三分仓空预器三种类型，采用清洁因子作为受热面灰污染状况的指标。
