Open the CIPO recordAbstract From the Canadian patent
A method for burning fuels, particularly garbage in incinerators with a stoker grate, for which the primary air is supplied below the stoker grate into the fuel layer and the secondary air is supplied above the fuel layer is controlled in such a way that the intensity of the combustion of the fuel on the stoker grate is increased by increasing the oxygen content of the primary air and the intensity of the combustion in the secondary combustion zone is choked by decreasing the oxygen content in the secondary air. Flue gas preferably from the combustion process is recirculated in order to reduce the oxygen content of the secondary air.

Why it's free to use
- Filed April 14, 1994 and granted February 8, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 14, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
