Abstract
Methods and apparatus to improve industrial combustion efficiency are disclosed. One disclosed example method includes providing sorbent to one or more of a combustion chamber or to flue gas exiting the combustion chamber after a combustion process. The disclosed example method also includes providing the flue gas to a hot gas filter after the flue gas exits the combustion chamber.
Claims48
A method comprising:
- providing sorbent to one or more of a combustion chamber or to flue gas exiting the combustion chamber after a combustion process;
- and
- providing the flue gas to a hot gas filter after the flue gas exits the combustion chamber.
A method comprising
- providing sorbent to a combustion chamber, wherein the sorbent is provided to fuel, combustion air, or a mixture of fuel and combustion air prior to being provided to and combusted in the combustion chamber;
- and
- providing flue gas from the combustion chamber to a catalytic filter.
An apparatus comprising
- a combustion chamber of a boiler plant wherein sorbent is provided to the combustion chamber or provided to flue gas after the flue gas exits the combustion chamber during a combustion process;
- and
- a hot gas filter of the boiler plant to receive the flue gas and reduce acid-forming compounds or pollutants from the flue gas.
A method comprising:
- providing at least one type of sorbent to one or more of a combustion chamber or to flue gas exiting the combustion chamber after a combustion process;
- and
- condensing at least one vaporized component from the flue gas after the flue gas exits the combustion chamber to form a condensate.
A method comprising:
- providing at least one sorbent to one or more of a combustion chamber of a boiler plant or to flue gas exiting the combustion chamber after a combustion process;
- and
- cooling the flue gas to a temperature below at least the highest dew point of any condensable component remaining after the flue gas exits the combustion chamber.
An apparatus comprising
- a combustion chamber, wherein sorbent is provided to the combustion chamber or provided to flue gas after the flue gas exits the combustion chamber during a combustion process;
- and
- a condenser to condense at least one vaporized component from the flue gas to form a condensate, whereby the condensate is optionally provided to a boiler feed, an additional heat exchanger or an alternative condensate consuming process.
