the covered lid with cutting trestle, which is served by the loader Golgotha, small or lump wood, as well as any lump of vegetable raw materials, not scattered during pyrolysis. The wood split on the overpass saws or chainsaws.

After ignition uglevyzhigatelnuyu furnace, when the flue gases will have quite a high temperature, are removable exhaust pipe and closes the lid of the furnace.

Flue gases from the combustion zone 28 upward (upward flow 38) and cooling down due to the heating of the raw material, the evaporation of moisture and the elements of the furnace (downward flow 39), enriched with water vapor and products of pyrolysis (steam and gas), down closer to the sides of the case fall within the annulus 29 and through the channels 35 and pipe 36 are released into the atmosphere.

Traction is provided by the location of the combustion zone below the level of the exhaust steam and gas from the furnace, adjustable height removable pipe 36 and control valve 33.

Part of the flue gases, become flammable due to the products of pyrolysis and calcination coal (steam and gas) are sucked into the (ejected) in the combustion zone, which saves raw materials consumed as fuel.

After reaching the temperature at the exit of steam and gas above the temperature of decomposition of the raw materials (according to the testimony of termopane to the temperature at the exit of steam and gas 100-120C. Submission of finely sprayed water accelerates the cooling of the coal and the furnace and simultaneously prevents the formation of explosive mixtures because of the possibility of air leaks during cooling of coal and furnace. Then removed the pipe 36, the hydraulic shutter 37 is closed by a cover 41. The furnace is placed on the cooling of the coal to a temperature of 40C.

After complete cooling of the furnace opens the lid, and, having ascertained that the coal is completely cooled, it is unloaded by turning the furnace above the floor with pins 44 for holding and packing of coal.

Option unload coal from the furnace pneumatically through the access hatch 42. Ash is removed from the cavity 27. Next, the furnace is loaded and the cycle repeats.

The coal then is loaded into paper or plastic bags and stored under cover.

The use of the invention will increase the time of operation of the furnace by performing the mating structural members to avoid their deformation under alternating temperature loads by free expansion or contraction, which are controlled by a hydraulic gate, performing a cover in the form of a membrane, suspended to a pole, the location of the bottom of the annular groove is="text-align:center; margin-top:2mm;">Claims
