The invention relates to the field of environmental protection and is intended for pyrolysis of wood waste, wood and can be used for the production of charcoal.

A device for pyrolysis of wood, comprising a furnace, a heating chamber and removable vertical retort with openings for the exit of the pyrolysis gases in the lower part of the retort (RU # 1790209, WITH 10 IN 53/02).

A disadvantage of the known device is that it does not provide integrity, as in the pyrolysis of wood leak pyrolysis gases through the openings of the combustion device, channel or flue pipe and chimney flue they enter the atmosphere.

A device for pyrolysis of waste, including a furnace, a heating chamber and removable vertical retort with the possibility of exit of the pyrolysis gases in the lower part of the vertical removable retort equipped with cast-iron plates, which is tightly fitted the retort, and the ducts to the furnace (RU # 2164239, WITH 10 IN 1/04, F 23 G 5/00, prototype)

A disadvantage of the known device is that it does not ensure the integrity of the structure during operation cast-iron plates in conditions of thermocycles iron becomes brittle in terms of mechanical properties and does not ensure the integrity of the process of pyrolysis gases (hereinafter referred to as Tex is in - Pirogov) from the vertical removable retort in the flue. In other words, each time placing cold vertical removable retort on a hot iron plate, it cracks and goes through them pirogis are removable from the vertical retort directly into the heating chamber further out into the atmosphere through the hole in the wall of the heating chamber, which leads to environmental pollution.

The design of the proposed device devoid of the above disadvantages and differs from the prototype in that provides environmental cleanliness in the process of pyrolysis of wood waste, wood: prevent emissions Pirogov into the atmosphere by eliminating leakage Pirogov in the heating chamber.

The proposed device for pyrolysis of wood waste including furnace heating chamber and removable vertical retort with output Pirogov in the lower part of the retort equipped with a stove and flue for the furnace, the plate is made of heat-resistant material and is made with a hole in which is installed and fixed mounted exhaust Pirogov in the flue and the stove is the design of heat-resistant granular material, which is tightly fitted the retort.
