Thermal power plant uses coal as fuel for their working. Coal after burning leaves ash. Disposal of this ash is also one important task. Ash comes in contact with open environment and has adverse effects on health of human being. Due to these various health problems like skin diseases, breathing problem etc. are started in man working under those premises. Some other elements like boiler, turbine, generator, material handling are those elements due to which hazards and accidents take place while operation and maintenance of these. This work focuses on identification of various Occupational diseases and injuries, health risks associated with the man power working in thermal power plant. This data were collected by questionnaires and personnel interview of the workers working in different section of the thermal power plant like boiler section, turbine & generator section, coal & ash handling plant, hydrogen plant etc. Analysis is done in terms of different variables, such as age, skills experience, type of injuries and type of diseases. Results are shown in the form graph and chart. The results indicate a remarkable and visible impact on health of workers during operation and maintenance.
The production rate of a machine in an industry is expected to be high as much as possible. Deviations in the rate of production due to any miscellaneous factors can be avoided. Obviously, human errors are unavoidable. At the same time necessary actions should be taken to minimise the deviations to the negligible level. Nyloc nut, a solid component is a special type of fastener. Nyloc nut production is essential in order to reduce the vibration during motion. The vibratory feeder in choking machine (SSNA 14) can be replaced with the help of appropriate mechanism to reduce the power loss due to vibration. To overcome this, a suggestion as design of a prototype has been made, which is simple in construction and produces less vibration and noise compared to the existing one. It also reduces the idle time of choking machine (SSNA 14), due to the misalignment of the components from the track. The section which combines both the nyloc and nut in the existing machine is fine. But a disturbance arises because of vibration in vibratory feeder. In this project, the replacement for the feeder is provided as a suggestion through a design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
