Heat accumulating-type aluminum melting furnace

The regenerative burner is with pair arrangement, relative two burners forone group (A, Bburner). Air from the air blower out by reversing valve switchs into a regenerative burner 1, 4, after the regenerative burner 1, 4, ceramics ball heated in a very short time, temperature air heating furnace temperature (generally close tothe furnace temperature for 80-90%). The heating furnace temperature hot air to enter, roll around the furnace flue gas suction a 21% oxygen levels below the thin air, temperature and poor oxygen into thin air temperature near, fuel injection fuel burning in poor condition; oxygen, Meanwhile, the hot flue gas chamber after another two regenerative burner 2, 3 vented to atmosphere, high temperature hot flue chamber through a regenerative burner 2, 3 will show thermal storage in regenerative burner 2, 3 within the body, then heat with low smoke than 150 degrees by reversing valves. When the regenerator of saturation heat storage when switching commutation, the regenerative burner in heat and working status, so as to achieve exchanged between energy and reduce NOX emissions, etc. (1) the remarkable energy saving, energy saving 30% above than traditional heat regenerator "limit because the flue gas recovery" in most of the heat, and the participation in the media with burning down, greatly reduce the stove hot spending, so the regenerative heat stove technology energy than conventional furnace. (2) eliminates partial high temperature, low temperature distribution in uniform fuel combustion, under the condition of oxygen concentration in the furnace of fire formed without stable diffusion flame, eliminating the flame stability of local high, With the flame furnace, almost more uniform temperature. The regenerative burner, frequent exchange of working condition of gas stove fire and frequent change flow direction, strengthen the convection, reduce exhaust gas furnace temperature, and also make blind more evenly. (3) improve heating quality Even more evenly heating furnace to aluminum, reduce the temperature and the local environment for aluminum liquid oxygen enrichment of volatile and oxidation. (4) prolonging furnace refractories life-span Local high temperature uniformity and eliminate heated evenly, make refractories and refractory materials always work on the use of reasonable temperature range. The air in the furnace is preheated before entering into close of furnace temperature, furnace refractories ReZhen relieved. 5) to reduceCO2emissions of greenhouse gases and NOX production Fuel saving 30%, the corresponding also reduceCO2 emissions by 30%. Due to the elimination of local high effective, reduced NOx cargoes.
