COMBUSTION METHOD OF WOOD WASTES, AND HEAT GENERATOR FOR ITS IMPLEMENTATION WITH HEATER AND HEAT EXCHANGE CHAMBER AND COVER PLATE OF COMBUSTION CHAMBER Russian patent published in 2013 - IPC F24B1/00 

FIELD: heating.

SUBSTANCE: combustion method of wood wastes with heat recovery involves fuel supply to a loading hole of the combustion chamber, its ignition with air supply to the combustion chamber through an air intake channel, extraction of flue gases through an expansion chamber with adjustable exhaust airflow, and heat is extracted with heating agent passing through the heat exchanger with cleaning of flue gases from solid particles prior to the beginning of heat removal process, and then, after heat removal with further discharge of exhaust gases to atmosphere. Flue gases entering a separating chamber are divided into two flows, each of which rotates in a circumferential direction about a vertical virtual axis passing through centre of the heater holes and flows upwards to the holes of the heater that extracts the heat with heating agent from two divided flows by passing them easily through those holes for combination of those two flows in the heat exchange chamber and levelling of the combined flow for extraction using heating agent with transverse flow of movement and common direction of its upward movement, which coincides with movement direction of flue gases, heat passing through the heat exchanger, with its cleaning in the heat exchange chamber and before it is discharged to atmosphere. Besides, heat generator, heater, heat exchange chamber and cover plate of combustion chamber of heat generator are described.

EFFECT: increasing the efficiency of heat recovery process and flue gas cleaning process, excluding damage to lining, increasing service life of heat generator, reducing additional costs for its manufacture and operation, improving maintenance process and simplifying assembly process; using less energy-intensive equipment and reducing fire hazard.
