Alternate Solution for effective Dust Suppression in Thermal Power Plant

Many thermal power plants use coal as their fuel. To handle the coal, each power station is equipped with a coal handling plant. The coal has to be sized, processed, and handled which should be done effectively and efficiently. While working in the coal handling plant the major factor which reduces staff efficiency is the working environment i.e. a dusty atmosphere. Lots of care is always taken to reduce dust emission. Generally all systems used in power station coal handling plants are wet dust suppression systems. In this paper the reasons for failure of these type of dust suppression system are discussed. The remedy for the improvement of this system is also given in this paper. The existing system can be easily modified by using ultrasonic system. The spray discharge should be proportional with dust emission. The solenoid valve should be open with proportion with quantity of dust generation. The possibility of such type of this system is discussed in this paper
