METHOD FOR REMOVING AIR NOT PARTICIPATING IN THE COMBUSTION OF SOLID FUEL IN THE BOILER, THE BOILER WITH THE MECHANICAL SUPPLY OF SOLID FUEL AND THE METHOD OF MODERNIZING SUCH BOILER

摘要

1. The method of removing air that is not involved in the combustion of fuel in the furnace of a boiler with mechanical supply of solid fuel containing a furnace, movable means for supplying solid fuel and a pallet space in which there is an air supply system to the furnace containing air chambers and an air duct for supplying atmospheric air to said air chambers, characterized in that the air is removed from the pallet space surrounding the air chambers of the air supply system of the furnace to an additional air duct with an integrated fan, the air discharge power of which is controlled using the temperature difference of the air supplied to the air chambers and the air in the additional duct. ! 2. The method according to claim 1, characterized in that from the additional duct the air is supplied to the air chambers of the air supply system to the furnace. ! 3. The method according to claim 1, characterized in that the air is discharged into the atmosphere from the additional duct. ! 4. The method according to claim 1, characterized in that from the additional duct, air is supplied to the secondary air discharge duct to the furnace. ! 5. A boiler having a furnace, a secondary air injection duct into the furnace, movable means for mechanically supplying solid fuel to the furnace, a pallet space in which there is an air supply system to the furnace, including air chambers, as well as a main air duct for supplying atmospheric air to the air chambers and additional duct with a built-in fan with adjustable air discharge power, in which the inlet is connected to the pallet space surrounding the air chambers of the air supply system in
