Incinerator with pivoting grating system

The invention relates in general to waste disposal and, more particularly, to waste disposal by incineration.

In a traditional incinerator system, waste is moved into a furnace where it is burned at high temperatures. The furnace includes a grate on which the garbage is supported while it is burned. To facilitate combustion, air is supplied from below the grate. The air travels up through openings in the grate.

During the incineration process, some materials, such as glass and plastic, may melt before they burn. Some of the melted material collects on the grate. Over time, the amount of material that collects on the grate begins to appreciably inhibit airflow, which in turn adversely affects the combustion process. If the amount of airflow blockage becomes too great, then the grate must be replaced or cleaned. Both of these options are time consuming, labor intensive and expensive.

Thus, there is a need for an incineration system that can minimize such concerns.

In one respect, aspects of the invention are directed to an incinerator system. The system includes a combustion chamber and a grating system. The grating system includes a first panel and an opposite second panel. Each of the first and second panels supports a plurality of bricks. At least a portion of each panel is housed within the combustion chamber. The first panel and the second panel are angled relative to each other so as to be arranged in a generally v-shaped configuration.

Each of the first and second panels are pivotable. The first and second panels can be independently pivotable. The first panel can include an associated pivot point, and the second panel includes an associated pivot point. The pivot point of the first panel and/or the pivot point of the second panel can be located in an upper end region of each panel. The first panel and/or the second panel can be pivotably mounted to any suitable structure, including structure located outside of the combustion chamber. In such case, a portion of the first panel and/or second panel can extend outside of the combustion chamber.

An arm can be operatively connected to each of the first and second panels. Pivoting movement of the first and second panels can be achieved by movement of the arm. The arm can be a hydraulic arm. In one embodiment, a timer can be operatively associated with the hydraulic arm. Thus, the panels can be pivoted on a predetermined timed basis.

At least one of the bricks can have a channel extending therethrough. Each channel can be fluidly connected to an air source. As a result, air can enter and flow along the channel.

In another respect, aspects of the invention are directed to an ash removal system. The system can include a first auger and a second auger. The second auger can be located below the first auger. The first auger can have a rib that can break up combustion products, such as ash. The first auger can include a plurality of passages therein to deliver dense air to the combustor help in the final burning of the garbage. The second auger can be used to transport the products of the incineration process out of the combustor for disposal. The first auger and/or the second auger can rotate at a variable speed. The direction of rotation of the first auger and/or the second auger can be reversible. The first and second augers can be at least partially submerged in a fluid, such as water.

In another respect, aspects of the invention related to a method of incinerating garbage. Garbage can be supplied to a combustion chamber which can includes a grating system with a first panel and an opposite second panel arranged in a generally v-shaped configuration. Each of the first and second panels can support a plurality of bricks. Each of the first and second panels can be pivotably mounted in the combustion chamber. According to the method, garbage can be supplied to the combustion chamber and supported on the grating system. The garbage can be burned. To facilitate burning, the garbage can be agitated by pivotally moving the first panel and/or the second panel, thereby allowing air to mix with the garbage. To further facilitate burning, pre-heated air can be to the combustion chamber by passing air in heat exchanging relation through a channel in one or more of the bricks.

In still another respect, aspects of the invention can be directed to a brick for an incinerator. The brick can be made of a refractory material. The brick can provide one or more planar regions for engagement with other bricks. One or more channels can extend through the brick. The brick can be positioned so that a portion of the brick overhangs an exit end of each channel.

In yet another respect, aspects of the invention are directed to a grating panel for an incinerator. The panel can include a support rack formed by frame members connected by a plurality of rods. A plurality of bricks can be removably mounted on the support rack. The bricks can be arranged in a cascading manner on the support rack.
