Abstract: A control system for controlling the utilization of heated waste streams for fluidizing particulate matter such as coal in a fluidizing bed dryer. The control system includes a number of graphic user interfaces that allow an operator to more easily monitor and/or control the various regulator devices. The control system controls coal handling or transportation, fluid handling or flow, and the discharge of discarded or separated coal from the dryer.

Abstract: The present invention relates to a device for feeding shredder dust to a furnace such as a reverberatory furnace. This device comprises a feeding chute that passes to the inside of the reverberatory furnace and is fitted to the ceiling of the reverberatory furnace. Shredder dust can be fed from this feeding chute which also allows oxygen enriched air to be supplied to the feeding chute and fed to the inside of the reverberatory furnace. Further, the present invention relates to a reverberatory furnace in which a burner is able to be installed in a wall portion of one end side thereof. A plurality of feeding ports to which are connected the feeding chutes of the shredder dust feeding devices are provided at the one end side in the ceiling portion thereof forming a plurality of staggered rows facing the other end side.

Abstract: The present invention relates to facilities for feeding shredder dusts to a reverberatory furnace in which shredder dusts is fed to a reverberatory furnace for non-ferrous smelting, and in particular, to facilities for feeding shredder dusts to a reverberatory furnace in which a feeding chute that passes to the inside of the reverberatory furnace is fitted to the ceiling of the reverberatory furnace and shredder dusts can be fed from this feeding chute, and which also allows oxygen enriched air to be supplied to the feeding chute and fed to the inside of the reverberatory furnace.

Abstract: An inexpensive trash incinerator having a primary burn chamber and an after burner which includes a spark arrestor. The after burner is a stack which rests on top of the primary burn chamber and it includes an opening in its lower end for admitting fresh air into the after burner.

Abstract: A vibrating bed pyrolysis system has a vibrating bed which is supplied with hot solid particles. Dry coal particles are rapidly heated by the hot solid particles to drive off hydrocarbon vapors. The vapors are condensed in a jet condenser, and products are flowed to a header tank. A portion of the liquid product is stored at room temperature for later use. A small portion of the liquid product is pumped from the header tank and cooled to ambient temperature and is sprayed in the jet condenser, which is positioned above the vibrating pyrolysis bed. A dryer bed vibrated by the same vibrating machine which vibrates the pyrolysis bed is supplied with hot solid particles and the crushed coal. Moisture in the coal particles is evaporated, and water vapors entrain coal fines before the coal particles are passed to the pyrolysis bed. The hot solid particles are taken from a fluidized bed combustor and are returned to the combustor with the coal char particles by entrainment into the gas lift system.

Abstract: According to the invention it is suggested that, in a heating boiler with a vibrating grate (3), a supply pipe (6) from which fuel material in particle form, in particular pellets, is supplied to the grate, is mechanically connected to the grate (3) and arranged to freely support the grate, which is thereby freely suspended in the combustion chamber without contact with the bottom and walls of the combustion chamber. A vibrating means (19) is also mechanically connected to the supply pipe (6) and arranged to produce a rectilinear movement and to function as drive source to feed the fuel particles to the grate via the supply pipe (6). The vibrating means gives the fuel particles a toss movement obliquely upwards and forwards in the supply pipe and on the grate whereby the fuel particles move onto the grate and towards the end of the grate opposite the supply pipe (6).

Abstract: Solid fuel such as coal is fed into an inlet shaft of the furnace through a rotary feeder constructed to prevent the admission of air. Primary air channels supply the major part of the air required for combustion of the fuel in a region in which the fuel bed is sufficiently thick to avoid disturbance and the formation of "holes" by this air. Further, narrower air channels supply sufficient, diffused and low velocity air to complete the combustion of the fuel without substantial entrainment of grit and ash. Air is prevented from flowing in contact with the fuel up stream of the primary channels and the metering edge.
