The utility model content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of fuel without interruption is provided, and makes continuous, the stable high-temperature thermal storage type burner of flame.
High-temperature thermal storage type burner described in the utility model comprises body of heater, and body of heater is provided with at least 1 nozzle that sprays into fuel and is at least two regenerator that are connected with the burner block of body of heater of even numbers.
Wherein, described nozzle is connected with fuel system with air blast, and per two regenerator are connected with two outlets of same four-way change-over valve respectively, and two other outlet of four-way change-over valve is connected with air-introduced machine with air blast respectively.
The last plane of the through hole of described burner block tilts towards its lower plane, and its inclination angle is identical with the setting angle of nozzle.
Described four-way change-over valve comprises valve body and spool, described valve body has four ventilating openings, between four ventilating openings, be provided with four orthogonal air doors, described spool has turning cylinder, on turning cylinder, have two retaining doors, on the two sides of the one side of air door or shelves door, have anticorrosion refractory seals plate.
The material of described anticorrosion the is high temperature resistant close plate of temperature is fluorubber or silicon rubber.
The advantage that scribbles fire resistant anticorrosive paint high-temperature thermal storage type burner described in the utility model on body cavity and orthogonal air door is:
1, existing production of existing high-temperature thermal storage type burner and potential safety hazard have been solved, because nozzle and regenerator are divided into two parts, fuel and hot-air are respectively by the through hole supply of nozzle and the burner block that is connected with regenerator, the influence that hot-air is interrupted is not supplied in the supply of fuel, can be without interruption, thereby flame continuously, stable, therefore do not have obstruction, coking, cutoff, do not fire, phenomenon such as detonation.
2, energy-saving effect is remarkable, the about 30-50% of energy savings;
3, increase output,, thereby institute's heating products output is increased because the rising of its combustion air temperature causes quick heating in the heating furnace;
4, environment protecting is remarkable, because that the end falls in exhaust gas temperature is low, a large amount of saving of the energy cause SO 2, CO 2Discharge capacity also correspondingly reduced about 30-50% NO xDischarge capacity also significantly reduce;
5,, can reduce oxidization burning loss about 0.5% for being the production of product with the metal.
