HEAT GENERATOR FURNACE FOR BURNING WOOD WASTES AND HEAT GENERATOR Russian patent published in 2020 - IPC F23B40/00 F23G5/27 

FIELD: power engineering.

SUBSTANCE: heat generator furnace using wood waste includes cylindrical housing made of shells, rigidly attached to each other and forming internal volume of furnace. Each shell comprises cylindrical air chamber and inner lining with refractory material. Air chamber is connected to appropriate blower and communicated by means of blow nozzles with internal volume of furnace. Inside the lower shell there is a combustion chamber, in the wall of which there is a window, in which there is at least one device for loading wood wastes onto the bottom of the combustion chamber, wherein at least part of the inner wall of the combustion chamber adjacent to the bottom of the combustion chamber and located opposite the loading device is tapered, converging to the said combustion chamber bottom, a row of upper shells forms a space above the combustion chamber, and inside upper shell accommodating mixing chamber, between space above combustion chamber and mixing chamber there is flow diverting baffle, above mixing chamber there is pipe connecting mixing chamber through control valve with atmosphere, and at the outlet of the mixing chamber, which is the heat generator's outlet, an exhauster is installed, note here that heat generator is equipped with blower operation mode control device, loading device and controlled gate valve.

EFFECT: raised efficiency of heat energy generation due to more complete burning of wood waste and increased time of non-stop operation of furnace and heat generator as a whole.
