A furnace, especially a fluidized furnace with a combustion chamber (1) that gas flows up through and that has a gas outlet provided with a second flue (2) and a precipitator (10) for separating solids from the flue gas. The solids end of the precipitator communicates with the second flue, which accommodates a layer (12) of solid matter. The bottom of the second flue communicates by way of a solids-reintroduction line (14) with the combustion chamber. The second flue is a solids cooler and the precipitator is also a filter.

Furnace, especially a fluidized furnace

To allow liquid and/or gaseous fuels to be burned with decreased NO.sub.x formation, the combustion air is fed in at axial intervals one after the other. The percentage of primary air is higher than that of secondary air. The injector effect of the primary air draws flue gas out of the firebox and supplies it to a flame-initiation point between the primary-air and secondary-air feeds.

Method of and burner for burning liquid or gaseous fuels with decreased

A steam generator in which a main boiler is provided and at least one fluidized bed furnace is connected with the main boiler and is operated independently of the furnace of the main boiler. The fluidized bed furnace is connected with the main boiler underneath the boiler funnel. The tubes of the boiler funnel are partially fanned out and form flue gas passages, through which the flue gas of the fluidized bed furnace flows into the combustion chamber of the main boiler.
