Abstract

Thermal power plants are one of the noisiest processing plants. However, regular exposure to industrial noise can't be avoided which might be the reason for the neurobehavioral change, mental pressure and misery in day by day existence without demonstrating the manifestations of chronic/acute diseases. In industry, excessive noise exposure can cause both auditory and extra-auditory effects. The most important of these is hearing damage resulting from prolonged exposure to excessive noise. Another undesirable effect is speech interference or interruption of communication. Annoyance is the third undesirable effect of noise. Laboratory studies have demonstrated that clamor diminishes productivity on a few undertakings, can agitate the feeling of adjusting and can cause veins to choke, raising blood pressure and reduce the volume of the blood stream. Thus a complete noise reduction system is required to measure, monitor and reduce the noise level in a thermal power plant. The scope of this project is to propose a chamber based silencer muffler design for draft fans, which plays an important role in thermal power plants. Draft fans (Forced Draft (FD Fan) and Induced Draft (ID Fan)) regulate the air pressure inside the boiler system.
