DETAILED DESCRIPTION OF THE INVENTION

(6) The charging system for dust-free fuel charging consists of loading chamber 1, a container 2 for fuel, and a belt conveyor 3, transporting fuel to the charging chamber of the stove 23, located in a closed chamber 4.

(7) Rectangular lower part, charging 1a, of the bipartite loading chamber 1, is closed at the lower part by a arched profiled surface of the bottom 6, arranged at an angle in relation to the walls of the chamber 1a, wherein the surface 6 in the lower part is connected with the chamber 4 of the belt conveyor 3. In the lower part of the chamber there is an inlet of suction port 7 of the turbine 5, which is started when the container 2r is placed in the chamber 1r, sucking in air together with the dust generated in the chamber when fuel is being poured out.

(8) In the upper part, charging chamber 1 has cylindrical shape, in which the top edge 8 has arched outline, forming funnel profile, which is closed at the inlet by a flexible membrane 9. The membrane seals the container junction with the chamber, preventing dust from getting out during fuel pouring. The ratchet mechanism 10, which stabilizes position and motion of the container 2 in the chamber, is arranged on the external surface of the chamber 1.

(9) The container 2 consists of cylindrical body and the cover 12, preferably made of plastic material and separably fastened by a threaded connection 13,19. The toothed bar 11, which together with the ratchet mechanism 10, positions the container during fuel charging and fuel pouring process, is situated on the external surface of the container 2. In the bottom of the container there are symmetrically arranged pass-through holes 14, for draining water, contained in the fuel, and in the center of the bottom there is arched relief 15, wherein holder 16 is placed. The planar outline of the bottom allows to storage number of containers one above the other in vertical position. In the upper part of the container on the external surface, there are holders 17, symmetrically arranged on both sides, for moving and rotating the container during turning on and turning off the cover 12.

(10) The cover 12 has the cylindrical shape, wherein the upper surface of the cover—bottom 22, has a spherical profile, and the external surface is threaded 13. Spherical outline of the cover bottom 22, from the inside of the container 2, allows coal to pour out gravitationally to feeding pocket after turning on and shifting up the container. Rectangular pockets 18 are located on the planar part of the external cover 12. The pockets, when container 2 is being placed in the chamber 1, are fixed in the hooks 20, preventing rotational movement of the cover and its unscrewing from the container body. The hooks 20 are located in the middle of the brackets 21, which are mounted horizontally to the walls of charging chamber 1a. The brackets 21 are both the base and support for the cover 12. After turning on, the cover is supported on the brackets and the hooks 20 prevent from rotational movement of the cover.

(11) The system is operating as follows. During the feeding process, the container 2 is placed in the pocket of loading chamber 1. The container should be turned in such a way that hooks 20 in the loading pocket 1a hit the cut-outs 18 in the cover in order to stabilize and then turn on the cover 12. After the rotation needed to turn on the cover, user raises the container 2, separating it from the cover 12, which is being placed in the hooks 20 on the brackets 21. Driving out of he container is restricted by the ratchet mechanism 10, which locks up when the container body 2 is driven out on a fixed height between cover 12 and the container, which allows for gravitational fuel pouring out to the inside of the chamber 1a. At the same time the mechanism blocs up the vertical position of the body and its falling to the pocket. The fuel which is pouring out through the shaped surface of the bottom 6 successively is directed on the conveyor 3 and then transported in the chamber 4 to the charging chamber 23 of the stove. After complete emptying the container, user unlocks the ratchet in the mechanism 10, allowing for the vertical movement of the container 2. Then user inserts the container 2, moving it down vertically up to the stop, until the container is laced over the thread 13 of the cover 12. While the container is being returned, the cover is fastened to the container by means of threaded connection 13, 19, and the user removes empty container driving it out from the pocket by the hooks 16,17.
