Abstract: Transportable or stationary hearth-type furnace reactor (I), for the transformation of solid and paste organic materials to processed gas, comprises cubic reactor (1); vapor inlet (8); a chain conveyor (9); a cover with passages (12); and a supporting flame mechanism (16). Transportable or stationary hearth-type furnace reactor (I), for the transformation of solid and pasty, organic materials in gas process, comprises cubic reactor (1) (with an appropriate separator on the side panel outside the reactor, at the funnel (3) with a valve (4) to check air flow and at the lower end of the funnel, a screw-conveyor (5) is arranged that opens or enters by a opening into the reactor wall above a hot plate (6), where the hot plate (6) at the bottom of the reactor as multiple heating elements above heater (7) at lower surface), vapor inlet (8) (arranged under the screw-conveyor above the hot plate), a chain conveyor (9) (arranged over the entire length of the hot plate, in which rake elements (10) are fixed above the hot plate at certain distances, at the end of the chain conveyor, a shaft (11) (for collecting ash and residual substances) is arranged at the bottom of the reactor, which has a valve to check air flow and another screw-conveyor at the bottom), a cover with passage (12) (arranged on the heater (13) present on the upper surface of the chain conveyor, which separates the reactor into a gas production area (14), gas collecting area and a reaction area (15)) and a supporting flame device (16) arranged at the side of reactor space wall in the reaction area and in the cover of the reactor or in the upper side wall of a gas detector (17). Independent claims are also included for: (1) a method of transforming solid and paste, organic materials into processed gases, comprising (I), where on continuous going through the materials, which can be treated by (I) with the help of the mechanically propelled transport devices such as rake elements, scratching broom or hod screw; degassing takes place in the first stage under air-lock with 280-600[deg]C (preferably with approximately 500[deg]C) via an indirect lower heater of the hot plate and via an upper heater in the gas production area, in which the materials can be treated are transported with a high protection of approximately 5-10 cm by transport devices practice-grounded over the hot towards shaft; the gas primarily developed in the second stage under stochiometric air supply burned with approximately 850-950[deg]C in the gas collecting area and reaction area, in which the inflammable components of the volatile content (CH2 and CO) as well as the dampness are converted completely to CO and H2; and in the third stage the developed gases of the second stage are burned by air supply in a following area at approximately 1000-1200[deg]C to carbon dioxide and water; and (2) a method for separating thermal bonding material from construction units and work pieces in the material (in the form of rubber/metal or plastic/metal) for the recovery of the metallic construction units including an open-hearth furnace reactor comprising allowing in and drawing out (I) from the lattice boxes in clockwise direction.
