A method for burning lumpy stock is performed in at least one shaft which comprises a preheating zone, a burning zone and a cooling zone. Coal with a swelling index >1 is supplied together with a transport medium via burner lances which have burner tips. The coal together with the transport medium emerges into the shaft, wherein the temperature of the coal in the burner lances is kept below a temperature value at which melt phases of the coal that is used are formed. Here, for the transportation of the coal, use is made of a transport medium which, in the shaft, in the region directly adjacent to the burner tip, forms an oxygen-depleted atmosphere in order to delay the ignition of the coal after it emerges from the burner lance.

The present invention relates to a humidity detection-based pellet grill control method and a feeding system of a pellet grill, where the pellet grill is energized so that the feeding system thereof and a humidity sensor on the feeding system are in an energized state; and the humidity sensor is used to continuously monitor humidity of a fuel conveying channel of the feeding system in which a pellet fuel has been stored, so that a controller determines humidity level of a space environment or the pellet fuel in the fuel conveying channel. This can prevent the fuel that has become powdered due to moisture from drying into hard lumps again in the fuel conveying channel which can result in blockage of a screw conveyor, thus protecting the feeding system and reducing maintenance costs.

A system for thermally processing solid fuel to produce pyrolysis gases, syngas, tar, char, and/or torrefied products, which includes a bulk solids pump having a curved passage to move a feedstock therein and wherein the pump includes a spool supported for rotational movement. A sleeve shaped chamber or chambers surround all or a portion of at least an axial extent of said curved passage to permit containment of heated gases to heat solid fuel within the curved passage to thermally process the feedstock within the pump.
