An apparatus for drying a quantity of wood which comprises:
- a wood drying room which includes a plurality of walls having exterior surfaces, which walls define a generally unobstructed open interior space and a combustion-gas supply passage therebetween which are capable of being sealed;
- a combustion-gas generator provided with an air-inlet conduit for introducing fresh air for combustion use into a combustion chamber provided in a lower area of said combustion-gas generator,
- said combustion-gas supplying passage extending from an upper area of said combustion-gas generator to an opening in said wood drying room which opening is located at an upper portion of said wood drying room at one side thereof;
- an exhaust-gas discharging conduit extending to a chimney from a bottom area of said wood drying room, said chimney being located on a side of said wood drying room which is opposite said side at which said opening is located;
- a combustion-gas recovery conduit extending from said bottom area of said wood drying room to said combustion-gas generator;
- and
- a gas flow-rate control unit provided in at least one of said exhaust-gas discharging control or said combustion-gas recovery conduit, wherein said generally unobstructed open interior space is rectangular.
