In an improved method for reducing nitrogen oxide emissions from a furnace wherein at least one injector is attached to the furnace above the primary combustion zone a biomass or biowaste and water slurry is injected into the flue gas through the injectors. The biowaste or a biomass material can be supplemented with a fixed nitrogen source.

1. An in-furnace method of reducing nitrogen oxides in the flue gas comprising the step of injecting a fuel water supply comprising a slurry of water and a material selected from the group consisting of biowaste and biomass such that the material provides 0.4% to 2.0% nitrogen on a moisture free and ash free basis into said flue gas so that the material and water mix with nitrogen oxides in the furnace, the material being injected in sufficient quantity to promote a reaction between said nitrogen oxides in the flue gas and said material, so as to substantially reduce nitrogen oxide content of the flue gas and to maintain overall fuel lean conditions above the primary combustion zone.
