Analysis Of Results

Although it is important to test quality of coal used in thermal power station, it is more important to know how to interpret the data from the results. No single test can be used independently to determine the quality of coal. Machine interference is a significant problem in many manufacturing system and testing equipments. The variation of results for testing equipments may be due to various factors which need to calculate the uncertainty of measurement to show the accuracy of the machine. In case of coal testing laboratory, the plant layout and surrounding environment affects the performance of the system. The machine interference comes under variable cause which may effect on the result. This paper, proposes a methodology for constructing system performance measures, finding out the various factors responsible for variations in result. The study is based on performance of coal used in thermal power station in India. The paper deals with estimation of machine interference existence using variable control chart approach for coal testing equipments. The paper gives the solution for the coal testing laboratory to improve their performance. The analysis of results for such machine interference will be useful and significant for system designers and practitioners.

Analysis Of Results

The performance and maintenance of testing laboratories is a prime issue. The quality of coal test results not only depends on performance of individual results but it also depends on the performance of various tests in the same laboratory. Machine interference is a significant problem in many manufacturing system and testing equipment. The variation of results for testing equipment may be due to various factors which need to calculate the uncertainty of measurement to show the accuracy of the machine. In case of coal testing laboratory, the plant layout and surrounding environment affects the performance of the system. The machine interference comes under variable causes which may affect the result. This chapter proposes a methodology for constructing system performance measures, finding out the various factors responsible for variations in result. The chapter deals with estimation of machine interference existence using variable control chart approach for coal testing equipment. The analysis of results for such machine interference will be useful and significant for system designers and practitioners.

Deterministic Strategy

To solve the mismatch between heating quantity and demand of thermal stations, an optimized control method based on depth deterministic strategy gradient was proposed in this paper. In this paper, long short-time memory deep learning algorithm is used to model the thermal power station, and then the depth deterministic strategy gradient control algorithm is used to solve the water supply flow sequence of the primary side of the thermal power station in combination with the operation mechanism of the central heating system. In this paper, a large number of historical working condition data of a thermal station are used to carry out simulation experiment, and the results show that the method is effective, which can realize the on-demand heating of the thermal station a certain extent and improve the utilization rate of heat.

Mining Industry is often tagged as a polluting sector since it involves since it involves extensive resource exploitation by unsustainable methods. The techniques involved in mining cause tremendous destruction to the environment and health of people living in nearby areas. There is a growing consensus on sustainable and efficient mineral development which will avoid the clash between economic and environmental interests. Deployment of advanced and sustainable technological solutions in the entire mining process, fixing the gaps in its regulatory mechanisms and learning from the successes of specific domestic and international mining operations are certain solutions that have the capacity this sector more productive. The paper provides insights into the problems of mining sector and possible solutions to overcome these problems. It also provides examples of certain best practices adopted by mining corporations for sustainable coal mining. The paper also explores various methods and technologies which can be adopted by Thermal Power Plants to reduce their emissions and simultaneously conserve environment. An empirical study of Dahanu Thermal Power Station located in state of Maharashtra of India has been undertaken for this purpose to study the modern technologies adopted by them to lower their emission levels.
