BURNER Russian patent published in 2012 - IPC F23C99/00 

FIELD: power engineering.

SUBSTANCE: burner comprises two adjacent parallel vertical slot rectangular boxes of primary and secondary air, equal in height, equipped with vertical slot confusor attachments with double-sided closure angles, nozzles for spraying of liquid fuel, arranged in the vertical plane of symmetry of the primary air box in the vertical row, and nozzles for spraying of liquid-fuel sludge. Besides, nozzles for periodical spraying of liquid-fuel sludge are also arranged in the vertical plane of symmetry of the primary air box and are installed between nozzles for spraying of liquid fuel, at the same time all nozzles form a common vertical row and are installed with an equal pitch h_n=(0.5-1.5)·B₁, distance between output sections of the burner confusor attachments B₀=(0.5-3.5)·B₁, and width of the confusor attachment of the secondary air box in the output section B₂=(1.2-4.0)·B₁, where B₁ - width of the confusor attachment of the primary air in the output section, m.

EFFECT: reduced extent of fuel underburning and concentration of nitrogen oxides during burning of liquid fuel and liquid-fuel sludge.
