Abstract

A flame-tube boiler is provided with a system of burners for the low-NOx combustion of heavy oil, with an air box (8) that communicates with the cooled flame tube (1) by way of a central primary-air channel (16) that surround an oil-burner lance (17) and by way of secondary-air feeds (18) that surround the primary-air channel. The flue-gas line (19) communicates with the flue-gas outlet (7) and accommodates a precipitator (20), which has a solids outlet that communicates with a ring of nozzle pipes (24) inside the burner and opening into the flame tube.
