Slag (28) is formed during the combustion of solid fuels with a lower ash fusion temperature and covers parts of the solid fuel, prevents complete combustion and blocks the air supply, thereby leading to an interruption of the combustion process. According to the invention, the embers and the fusing ashes are mixed by means of a cleaning comb (22) and are discharged from the burner. The burner consists of rotating grate bars (25) which are arranged parallel to one another within the inner walls (1). The cleaning comb (22) moves between the grate bars (25); upwards between the grate bars (25); in direction of the burner opening; downwards under the grate bars; and finally in the direction of the burner flange (7). When the slag (28) adheres to the rotating grate bars (25), it is scraped off by the cleaning comb (22). The fuel supplied to a funnel (8) slides downwards by the force of gravity, the funnel lid (9) opens, and the fuel is pushed onto the grate bars (25) by the plunger (11). The plunger (11) has at least one opening (15) for secondary air (5) which also provides cooling. A blower (13) blows the ashes fallen through the grate bars (25) through a cut-out section in the burner floor (30) opened by the floor trap (20).

Boiler equipment includes: a combustion device including a combustion chamber to combust fuel supplied to the combustion device; a combustion furnace including a combustion chamber formed inside thereof; and a heat exchanger transferring thermal energy obtained by combustion of the fuel in the combustion device to water. The combustion device is directly connected to a wall part of the combustion furnace such that the combustion chamber of the combustion device faces the combustion chamber of the combustion furnace. The fuel is efficiently combusted in the combustion chambers of the combustion device and the combustion furnace, which are integrated with each other. Thus, almost no ash is generated.

Disclosed is a solid fuel boiler burner, used in central heating boilers for building structures and in other heat exchangers. The solid fuel boiler burner has a rotary combustion chamber mounted in the casing, which is equipped with aeration ducts and this unit is connected by hooks with a gear wheel which is mounted rotationally between two cage bearings. The gear wheel and the compensating and pressure plate have openings for the inflow of air from the blower chamber through an adjustable screen which controls the ratio of primary to secondary air injected into the ducts. Moreover, the worm fuel feeder has an axially placed aeration duct with outlet in the combustion chamber.

The present invention provides a method of generating combustible gas from organic feedstock, such as the organic components of municipal waste, and a reactor therefor. The feedstock is processed through a plurality of reaction zones within the reactor, wherein the environment of each of the zones facilitates physical or chemical reactions that work to transform the organic feedstock into one or more combustible gases that can be burned for energy production.
