Technological equipment analysis of automated monitoring systems of flue gases at power plants

Nowadays one of the priorities of Energy Strategy of Russia is to organize constantly operating systems of continuous industrial monitoring of harmful emission out of coal-fired power plants into the atmosphere. The given paper considers the equipment for production and environmental monitoring of home developers and manufacturers, operated at some power plants of the Russian Federation at the lower level of monitoring of gas emission. At this level, measurements on the basis of agreed and certified methods, gathering and conversion of primary information to a standard form, routine maintenance and monitoring of the functioning of measuring systems and auxiliary equipment are carried out. Various gas analyzers and gas sections can be used to determine the composition of the combustion products in organization continuous monitoring at power plants. The selection of specific gas analytical systems is associated with certain difficulties, since they all have their advantages and disadvantages. Moreover, it is necessary to take into account a lot of different factors and parameters for the optimal selection of the equipment. The task of gas analytical systems selection is multicriterial. Difficulties in solving this problem are caused by the fact that the criteria may contradict each other (for example, high technical capabilities may complicate the operation of the system and increase its cost) and they may not be quantified. The selection of gas analytical systems for production and environmental monitoring should be as objective as possible, independent of the preferences of individual experts and specialists. The presented description of the equipment for production and environmental monitoring allows for an expert comparison of the technical characteristics of gas analyzers. Based on the methods of substantiating decisions on the selection of the structure of equipment in innovative projects, conclusions are drawn from the results of the analysis performed on 11 expert- relevant parameters.The recent expert analysis can supplement the results of the preliminary survey by the personnel of the power plant or a at power plants applied for the development of the technical specifications. It is recommended to carry out a feasibility investigation in decision making, taking into account the features of the equipment, production conditions, safety requirements and serviceability.
