ABSTRACT:
This invention provides a variety of incineration furnace with modular fire grate apparatus for cylindrical incinerator furnaces of water jacket configuration. The invented fire grate module is provided with refuse dump agitation capability from underside of waste fuel dump on the fire grate and also with air supply function in the fire grate apparatus itself. The fire grate module basically comprises radially laid out and circumferentially arranged air supply pipings at an angular interval, an upstream coolant water jacket and a downstream coolant water jacket of the fire grate module being connected through two water channels of the air supply pipings, a central junction body to secure said air supply pipings, an air plenum encircling the coolant water jackets for admission of pressurized air into the air pipings of the air supply pipings, a moving grate supported and rotationally driven by at least two idler shafts and one or more drive shaft, a stationary grate mounted on top of the air supply pipings, and a reducer-attached drive motor connected to the drive shaft so that when driven by the motor the moving grate will perform a fluctuational agitation of the merry-go-round motion, thus providing agitational effect, more thorough air admission into the uderside and inside of dumped refuses in the incineration chamber, improved incineration capacity and the combustion efficiency as well as the significant suppression of generation of toxic gases.
