METHOD AND DEVICE FOR THERMAL PROCESSING OF WOOD IN THE HIGH-SPEED CIRCULATION OF PRODUCTS OF COMBUSTION OF GAS FUEL AND ADDITIONAL LOAD AT STACK Russian patent published in 2018 - IPC F26B3/04 F26B7/00 

FIELD: wood industry.

SUBSTANCE: method is carried out by: burning gas fuels - natural or liquefied gas with gas burners in a furnace with an open combustion chamber located inside the wood drying chamber, high-speed circulation of the drying agent - a mixture of gas combustion products with water vapour over the stack, continuous measurement by electronic temperature sensors "t" and relative humidity "ϕ" the gaseous medium, the automatic maintenance of the temperature"t"of the gaseous medium as a function of humidity "ϕ" when drying and as a function of time τ_to6p at heat treatment, which are selected from the developed table of drying regimes for the rock data and the thickness of the assortment and the time of the heat treatment process, the forced loading of the timber in the stack and the exclusion of outside air inside the chamber when the process is stopped. The device for drying and heat treatment of wood contains two axial marching fans, a gas furnace with an open combustion chamber, an automatic process control system, a reinforced concrete slab or a set of spring ties, a folding rails section, external stationary rails, a pallet truck and a U-shaped exhaust pipe.

EFFECT: improving the quality of drying and heat treatment of wood, reducing the percentage of rejects of finished products.
