Pollution Controlling Silencer

Birendra Kumar Sinha of Bihar created a pollution controlling silencer. It is an attachment to exhaust manifold of stationary engine for reducing carbon particulates from the flue gas and damping the sound as well as temperature. It comprises a cylindrical housing in which exhaust gas is allowed to expand and strike over fins embedded over internal surface of cylinder and perforated tubular fins. This result in dissociation of CO and CO2 present in the exhaust gas into carbon particulates, which can be removed periodically through opening (covered by lid) provided for this purpose. Carbon can be used as raw material for making boot polish and similar applications. The exhaust gas coming out from this kit has quite low temperature and results very low noise. It also helps in protecting from the problem of global warming and noise pollution.
