  • Publication number: 20130213281
    Abstract: A filter vessel for removing metal particles from exhaust, comprising a casing defining an internal chamber adapted to receive a flow of gas travelling along a flow direction; an electrostatic grid disposed in the internal chamber in intersecting relation to the flow direction, the electrostatic grid adapted to electrostatically charge metal particles in the flow of gas; a first electromagnet disposed on the casing in a downstream location along the flow direction relative to the electrostatic grid, the first electromagnet adapted to attract the electrostatically charged metal particles; a second electromagnet disposed on the casing in a downstream location along the flow direction relative to the first electromagnet, the second electromagnet adapted to attract the electrostatically charged metal particles; a controller configured to control the energization of the first and second electromagnets; and a metal particle collector for collecting electrostatically charged metal particles attracted by the first an

  • Patent number: 6257157
    Abstract: A refuse incineration plant is disclosed which utilizes a continuous rail system to transport refuse from a loading area into a burn core, from the burn core to an ash removal area, and back to the refuse loading area. Smoke and exhaust generated by the incineration process is sensed to control the incineration burn cycle, thereby allowing a variable burn cycle depending upon the composition of the refuse incinerated therein. Once sensed, the smoke and exhaust from the incineration process is exhausted into a filtration system having a main mixing tank and a number of filter condenser tanks coupled in series ascending/descending gaseous communication. The main mixing tank utilizes a series of baffle plates which aids in the mixing of the smoke/exhaust with water vapor as delivered within the main mixing tank by a series of water vapor spray jets. A cooling unit is also utilized to cool the mixture and aid in the condensation thereof.
