The methods and systems of the present invention reduce NOx emissions in combustion systems, e.g., power plants, boilers, furnaces, incinerators, engines, and any combinations thereof. The inventive process decreases NOx emissions from stationary combustion sources and provides improved utilization
The methods and systems of the present invention reduce NOx emissions in combustion systems, e.g., power plants, boilers, furnaces, incinerators, engines, and any combinations thereof. The inventive process decreases NOx emissions from stationary combustion sources and provides improved utilization of low-grade biomass and other waste fuels without slagging and fouling problems. The invention reduces NOx emissions while utilizing gasified fuels, including biomass and low-grade waste fuels, by gasifying solid fuels and injecting produced gas into a reburning zone of, for example, a boiler at relatively low temperatures and in relatively small amounts. By feeding the gas directly into a reburning zone, the need for gas cleaning is eliminated or substantially reduced as tars are burned in the flame and alkali species may be present at much lower levels than is the case with direct combustion applications.

The identification card printing system of claim 16, including a key card input for receiving a key card code, wherein the controller controls printer operation in accordance with a comparison between the key card code and a corresponding code stored in the memory of the supply circuit. 27. The card supply of claim 16, wherein the supply information is encrypted. 28. The identification card printing system of claim 27, wherein the controller is adapted to decrypt the encrypted supply information. 29. A method for use with an identification card printing system to manage a card supply having a card hopper containing a stack of cards and a supply circuit mounted to the card hopper and having a memory containing supply information relating to parameters of the card supply, the method comprising steps of: (a) retrieving supply information from the memory; and (b) using the supply information during processing of cards; and (c) controlling operation of the identification card printing system based on the supply information. 30. The method of claim 29, wherein: the supply information includes a remaining card count corresponding to a number of cards remaining in the stack; and the using step (b) includes: (b) (1) processing a number of cards; and (b) (2) updating the remaining card count in the memory by subtracting the number of cards that were processed. 31. The method of claim 29, wherein: the supply information includes a remaining card count corresponding to a number of cards remaining in the stack; and the using step (b) includes: (b) (1) retrieving the supply information from the memory; (b) (2) counting a number of processed or transported cards; (b) (3) updating the remaining card count by subtracting the number of processed or transported cards; and (b) (4) storing the updated remaining card count in the memory of the supply circuit. 32. The method of claim 29, wherein the using step (b) includes displaying the retrieved supply information to a user. 33. The method of claim 29, wherein the using step (b) includes checking card compatibility with the identification card printing system based on the supply information. 34. The method of claim 29, wherein the supply information relates to at least one parameter selected from a group consisting of card type, card size, card feature
