Abstract

DC60 (17/07/56) In the A1 to A3 burner kits, primary combustion air is brought in by the primary air tube 11 and fuel is taken in. The fuel tube 12 is mixed together and burned in the primary combustion chamber 13, where the combustion exhaust gas is sprayed to the inside ( interior 1a of the furnace1 with the first nozzle 16 In addition, the secondary combustion air heated in the regenerative The regenerator 20 is directed through the secondary air tube 22 to the second nozzle 23 near the first nozzle. and is sprayed into furnace 1 with a second nozzle 23. The first nozzle gradually decreases in diameter to the inside of the furnace. , the amount of air for the primary combustion that is taken through first air duct and the volume of air for the second stage combustion is directed through the second stage air duct. will be controlled in accordance with the temperature in the furnace In the Al to A3 furnace kits, the primary combustion air is brought in by the primary air tube11 and the fuel is taken in by the fuel tube. 12 are mixed together and burned in a primary combustion chamber13 where combustion exhaust gas is sprayed to the interior 1a of the furnance1. with the first nozzle 16. In addition, the secondary combustion air is heated in the regenerative. (regenerator)20 It is taken through a secondary air tube22 to the second nozzle 23 near the first nozzle. and is sprayed into kiln 1 with a second knoll. fuel The amount of pre-combustion air taken through first air duct and the volume of air for the second stage combustion is directed through the second stage air duct. will be controlled in accordance with the temperature in the furnace

Claims (1)

Claims (all) which will not appear on the advertisement page :Edit 8/6/2016 1. Combustion control method for burner apparatus using furnace apparatus. Combustion consists of: primary air tube for conducting primary Combustion air, fuel tube which is placed inside the primary air tube and conducts the fuel, secondary combustion chamber. first (primary combustion chamber) for combustion of air for primary combustion It is brought in by the first air duct and the fuel is taken in by the fuel pipe, the first nozzle for connecting the first combustion chamber to the inside of the furnace, the second stage air duct. Secondary air tube for conducting secondary combustion air heated in the regenerator and second nozzle located in the area. near the first nossel and blows the second stage combustion air brought in by the second stage air duct into the furnace. The furnace kit also includes: primary air control means for controlling primary combustion air brought in through primary air ducts, fuel control means for fuel control.
