Open the CIPO recordAbstract From the Canadian patent
In a premixed type of combustion of a liquid fuel at high pressure, the injection of the fuel (4c 4d), and its evaporation with a gaseous medium (5) is undertaken, in order to prevent premature ignition of the liquid/gaseous mixture in the burner itself at a, location where the droplets of the fuel from the fuel nozzles (4a, 4b) are screened from the flame radiation from the flame front of the burner. As soon as the fuel (4c, 4d) is pre-evaporated, i.e. leaves the duct (7a, 7b) via the inlet slot (1d, 2d) in the direction of the internal space (3) of the burner as a mixture (6), it absorbs practically no flame radiation. (Fig. 2)

Why it's free to use
- Filed December 13, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 13, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 13, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
