The major health hazards from smoke and dust are due to microscopic fine particles present in smoke as well as in dust. These fine particles, which are microscopic in nature, can penetrate into human lungs and give rise to a range of health problems such as irritation in eyes, a runny nose, throat infection, and chronic cardiac and lung diseases. There is a need to device such mechanisms that can monitor smoke in thermal power plants for timely control of smoke that can pollute air and affects adversely the people living nearby the plants. In order to solve the problems of low accuracy of monitoring results and long monitoring time in conventional methods, a real-time smoke and dust monitoring system in thermal power plants is proposed, which makes use of modified genetic algorithm (GA). The collection and calibration of various monitoring parameters are accomplished through sampling control. The smoke and dust emission real-time monitoring subsystems are employed for the monitoring in an accurate manner. A dual-channel TCP/IP protocol is used between remote and local controlling modules for secure and speedy communication of the system. The generic GA is improved on the basis of the problem statement, and the linear programming model is used to avoid the defect of code duplication with genetic operations. The experimental results show that the proposed smoke and dust monitoring system can effectively improve the accuracy of the monitoring results and also reduce the time complexity by providing solutions in a faster manner. The significance of the proposed technique is to provide a reliable basis for the smoke and dust emission control of thermal power plants for safeguarding the human health.

Aiming at the existing problems of the monitoring systems of most of the thermal power plants in China, an intelligent information flow based real-time monitoring system of thermal power plant (RT-MSTPP) is proposed. RT-MSTPP is based on the role-based access control (RBAC) model to control different users of business model and the data access, and then realizes the intelligent controlling of the information flow. By using RT-MSTPP, the real-time data of the central equipment in the plant is acquired, their operating state is evaluated and the inchoate fault is predicted. The operating results show that the management of the plant has been improved and the inchoate fault of key equipment can be detected and preliminarily diagnosed.

The process of coal combustion results in coal ash, 80% of which is very fine in nature & is thus known as fly ash. Presently, in India, about 120 coal based thermal power plants are producing about 90-120 million tons of fly ash every year. With increase in demand of power energy, more and more thermal power plants are expected to commission in near future and it is expected that fly ash generation will be 225 million tons by 2017. Disposal of fly ash requires large quantity of land, water and energy and its fine particles, if not disposed properly, by virtue of their weightless, can become air born and adversely affect the entire Environment. These earth elements primarily consist of silica, alumina & iron etc. and its physicochemical parameters are closely resembles with volcanic ash, natural soil etc. These properties, therefore, makes it suitable for use in ceramic industries and helps in saving the environment and resources.

The article discusses the features of the operation of environmental monitoring systems. A number of factors are determined that affect the organization of hardware and software support for such systems. The main factors are: the operation of the equipment in real time, various environmental influences, the specifics of the composition of sensors and connections, as well as a complex technology for servicing the equipment in an aggressive technological environment. The listed factors affect the structure, software, hardware components and design of environmental monitoring systems. When creating any complex systems, the distribution of work in time leads to the allocation of various design stages, and the ideas about the system being designed, reflecting its essential properties with varying degrees of detail, determine the constituent parts of the design process. The specificity of the stages for monitoring systems of thermal power plants is shown, determined both by the general features of these systems and by the peculiarities of their application in the technological processes of thermal power plants, among which the main ones are: the heterogeneity of the input units and devices, as well as technological objects of power plants; work in real time; programmable logic of smart sensors and multifunctional purpose of system components; the possibility of failures leading to a change in the functioning algorithm using the multiversion methodology; the presence of interrelated requirements for the accuracy and speed of information transfer. The work shows the content of work on the stages of designing monitoring systems, taking into account the specifics of their development. This specificity is most significantly manifested in the development of a technical proposal and a draft design. In a step-by-step design, after the end of each stage, an assessment of the main results obtained is carried out by comparing them with those required according to the terms of reference. The article presents an expert analysis that allows you to determine the acceptable implementation of a real-time operating system for hardware and software support for environmental monitoring technologies. Phar Lap ETS, VxWorks and NI Linux Real-Time operating systems are considered.
