Abstract

DC60 (17/07/56) In the A1 to A3 furnace unit, the primary combustion air is brought in by the primary air tube 11 and the fuel is imported. The fuel tube 12 is mixed together and burned in the primary combustion chamber 13, where combustion exhaust gas is sprayed to the inside ( interior) 1a of the furnance 1 with the first nozzle 16 In addition, the secondary combustion air is heated in the regenerator. The regenerator 20 is directed through the secondary air tube 22 to the second nozzle 23 near the first nozzel. And was sprayed into the kiln 1 with the second 23 nosel, the first nosel is gradually reduced in diameter to the inside of the kiln. , The amount of first-stage combustion air that is passed through First stage air duct And the amount of secondary combustion air taken through the second stage air duct Will be controlled according to the temperature in the furnace In the Al-A3 furnace unit, the prinary combustion air is brought in by the primary air tube 11 and the fuel is brought in by the fuel tube. 12 are mixed together and burned in the primary combustion chamber 13, where combustion exhaust gas is sprayed into the interior 1a of the furnance 1.

Claims (1)

Claims (all) which will not appear on the advertisement page: Amendment 8/6/2016 1. Combustion control method for burner apparatus using burner apparatus. This includes: the primary air tube for conducting the primary combustion air, the fuel tube inserted inside the primary air tube and the fuel carrier, the primary combustion chamber. First (primary combustion chamber) for first-stage combustion of air at Is brought in by the first air duct and the fuel is brought in by the fuel pipe, the first nozzle (first nozzle) for welding the first combustion chamber to the inside of the furnace, the second stage air duct. A secondary air tube for conducting secondary combustion air that is heated in a regenerator and a second nozzle located in the area. Near the first nosel and ejection of secondary combustion air brought in by the second stage air duct into the furnace. The furnace kit also includes: primary air control means for controlling the first combustion air brought in through the first air duct, fuel control means for fuel control. It is brought in through the fuel pipe, and secondary air control means for controlling the combustion air. The second stage is brought in through the second stage air duct, where the first nosel is gradually Reduced diameter from the primary combustion chamber to the inside of the furnace and has the ability to eject gas for high speed combustion into the combustion flue gas obtained by combustion air. Primary burns And fuel in the first combustion chamber, and where the combustion control method for the kiln unit is changed to the furnace unit: a first combustion mode (a first combustion mode) in which the temperature in the kiln As low as In the first temperature range, the fuel that is brought into the primary combustion chamber through the fuel pipe via fuel control means is burned with the first combustion air brought into the chamber. It is initially burned through a first air duct through a pre-controlled air route and the resulting combustion exhaust gas is blown up at high speed into the furnace through a nosel. A second combustion system (a second combustion mode) when the temperature in the kiln rises to Temperature range 2, which is higher than temperature range 1, the amount of fuel that is brought in through the fuel pipe by the fuel control method is increased from when it was brought in during the combustion of the 1st combustion system while The second Nosel blows the secondary combustion air brought in through the air ducts. The second step, with the second step air control path, enters the furnace. And the first Nossel will spew gas emissions For high speed burning into the furnace Flue gas for combustion resulting from combustion The primary combustion air is brought into the primary combustion chamber through the first stage air ducts and The fuel is initially brought into the combustion chamber through the fuel pipes. And hence Fuel that is not cheap The combustion residue in the combustion flue gas is burned with secondary combustion air in the furnace and a third combustion mode, when the temperature in the furnace rises to Temperature range 3, which is higher than temperature range 2, the first air control path turns off the air conduction for First stage combustion through air ducts And lowered from the second step of air control trajectory adjustment to increase The amount of secondary combustion air that was ejected from the second nosel into the furnace through the Second stage air duct And adjusting fuel control trajectory to increase the amount of fuel that is brought through Fuel pipe The fuel is then ejected from the first combustion chamber into the chambers through the first nosel. 2. The combustion control method for the kiln equipment set according to claim 1 also consists of the primary combustion air feeding pathway. means), which mixes the initial combustion air with the fuel before the fuel being brought through the fuel pipe is imported.
