Abstract
The recirculation combustion system is installed in the exhaust stream of a combustion chamber to increase exhaust cleanliness and thermal efficiency. The system directs hot exhaust gases through a filtering system to remove the larger particulate materials and pollutants, and then return the gas back to the combustion chamber. This system includes a baghouse unit, a molten metal reactor system with automatic feed and waste removal, a separator system, an active exhaust stack and recirculation line control system, and an automatic oxygen and recirculation gas mixing system.
Claims17
A recirculating system for use with combustion chambers, the system comprising
- a molten metal reactor in communication with a combustion chamber, wherein the molten metal reactor includes a bath of molten metal, an injection lance to direct combustion exhaust gases from the combustion chamber into the bath of molten metal, and an injection blower to force the combustion exhaust gases into the bath of molten metal at high pressure so as to distribute the combustion exhaust gases as bubbles in the bath of molten metal, wherein molten metal within the bath of molten metal acts as a catalyst, reacts with the combustion exhaust gases, and breaks down the combustion exhaust gases into constituent parts, consumes at least a portion of the constituent parts, and expels a reacted exhaust, wherein the reacted exhaust is primarily carbon dioxide;
- a flow controller to receive the reacted exhaust from the molten metal reactor and to regulate flow of the reacted exhaust between an exhaust stack and a recirculating path to the combustion chamber;
- and
- a flow mixer to receive the reacted exhaust from the recirculating path, mix the reacted exhaust and oxygen, and provide the mix to the combustion chamber.
A recirculating combustion system, the system comprising;
- a fossil fuel supply;
- a combustion chamber to burn fossil fuel from the fossil fuel supply, wherein the combustion chamber creates a combustion exhaust gas;
- a molten metal reactor to receive the combustion exhaust gas from the combustion chamber, wherein the molten metal reactor includes a bath of molten metal, an injection lance to direct the combustion exhaust gas into the bath of molten metal, and an injection blower to force the combustion exhaust gas into the bath of molten metal at high pressure as bubbles in the bath of molten metal, wherein molten metal within the bath of molten metal acts as a catalyst, reacts with the combustion exhaust gas, and breaks down the combustion exhaust gas into constituent parts, consumes at least a portion of the constituent parts, and expels a reacted exhaust;
- a flow controller to receive the reacted exhaust from the molten metal reactor and to regulate flow of the reacted exhaust between an exhaust stack and a recirculating path to the combustion chamber;
- an oxygen supply;
- and
- a mixer to receive the reacted exhaust from the recirculating path and oxygen from the oxygen supply, mix the reacted exhaust and oxygen to create a recirculated combustion gas, and provide the recirculated combustion gas to the combustion chamber.
