Description
Technical field
The utility model relates to a kind of heat-storage type burner, relates in particular to a kind of energy saving and environment friendly heat-storage type burner.
Background technology
Existing heat-storage type burner version is the axis centre position that fuel injection device is positioned at burner, blowing system is at the periphery of fuel injection device parcel, the characteristics of this version are that the flame tissue concentrates on the middle part, form sub-thread main flow flame, good rigidly, but there are two main shortcomings: the one, owing to be heat storage type combustion, air themperature is up to more than 800 ℃, NO
xThe thing growing amount sharply increases, and environmental protection index can exceed standard; The 2nd, when commutating in the heat accumulating type system, flue gas causes fuel injection device to be burnt out by high-temperature flue gas during from the burner internal reflux easily, influences burner service life.
The common practices that domestic and international prior art overcomes the above problems is: at shortcoming 1, adopt the air classification technology, the burner inner structure is designed to the version of multichannel air distribution, but this design can make the air distribution body structure too complicated, volume is too huge, and burner weight and cost increase greatly.At shortcoming 2, water cooling plant or compressed air cooling device are set in the interlayer between air and fuel injection device, to guarantee that fuel injection device is not burnt out by high-temperature flue gas, this design also can cause burner weight and cost to increase greatly on the one hand, on the other hand, when having increased water-cooling system or compressed air cooling system, it itself is exactly a kind of extra energy consumption that produces because of technology, and, if the design water yield or compressed air consumption are not enough or when breaking down, still can cause the damage of fuel injection device, thereby influence is produced.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the problem that above-mentioned prior art exists, a kind of heat accumulating high efficiency green burner to be provided, by changing the spray regime of fuel, make efficiency of combustion improve greatly, reducing NO
xThe discharging of thing, and, need not to use cooling device just can reduce the damage of equipment, prolong the service life of equipment.
For realizing the purpose of this utility model, provide following technical scheme:
A kind of heat accumulating high efficiency green burner comprises regenerator, the air distribution tube that connects successively, the burner with spout and outer wall, has the through hole that is extended to spout by the outside on the outer wall of described burner, and fuel injection unit is installed in the through hole.
Wherein, form the material spray angle between the axis of the axis of through hole and described spout.
Wherein, fuel injection unit is arranged in the length of the length of described through hole less than described through hole.
Particularly, through hole has a plurality of, and a plurality of through holes distribute around described spout.
Particularly, the axis of a plurality of through holes forms different material spray angles respectively with between the axis of described spout.
Wherein, the port of spout for surrounding by described outer wall.
The beneficial effects of the utility model embody in the following areas:
1, fuel injection unit makes air drag reduce greatly along the spout of oblique insertion burner, thereby reduces the demand of system fan blast;
2, the head of fuel injection unit is hidden in the outer wall of burner, avoids high-temperature flue gas to contact with fuel injection unit, thereby avoids fuel injection unit to be burnt out by high-temperature flue gas; And, cancelled the use of cooling unit, reduced relevant energy consumption;
3, adopt a plurality of fuel injection units to be different angles ground burner oil in spout, it is more even to make that fuel mixes with air, and efficiency of combustion improves greatly; And make fuel cross in different spatial point, avoided concentrating of flame tissue, reduced NO with air
xThe discharging of thing.

The specific embodiment
Shown in the structural representation of Fig. 1 the utility model heat accumulating high efficiency green burner, heat accumulating high efficiency green burner of the present utility model comprises regenerator 1, air distribution tube 2 and the burner 3 that connects successively, and burner 3 has spout 3a and surrounds the outer wall 3b (shown in Fig. 2 a, 2b) of spout; Wherein, the port of the spout 3a of burner 3 for being surrounded by outer wall has the through hole 4 that is extended to spout 3a by the outside on the outer wall 3b, and shown in Fig. 2 a, 2b, fuel injection unit 5 is installed in the through hole 4.
As shown in Figure 1, be provided with heat storage 1a in the regenerator 1, the top of regenerator 1 is communicated with spout 3a by air distribution tube 2, so that the air that is entered by regenerator 1 bottom is after heat storage 1a heating, top by regenerator 1 enters spout 3a via air distribution tube 2, mix afterwards by spout 3a ejection (shown in Fig. 2 a hollow core arrow), and with the fuel (shown in filled arrows among Fig. 2 a) that is sprayed by fuel injection unit 5, fuel is in body of heater (not shown) internal combustion.
Form the material spray angle between the axis of the axis of through hole 4 and spout 3a, as shown in Figure 3, make fuel (among Fig. 3 shown in the filled arrows) and spout 3a axis inclination certain angle spray into spout 3a.And fuel injection unit 5 is arranged in the length of the length of through hole 4 less than through hole 4, makes the head (end of fuel ejection) of fuel injection unit 5 be hidden in the through hole 4.Shown in Fig. 2 b, when commutation, this moment, fuel injection unit 5 stopped burner oil, flue gas (shown in Fig. 2 b hollow core arrow) in the body of heater (not shown) flows into regenerator 1 through spout 3a, because the head of fuel injection unit 5 is hidden in the through hole 4, fuel injection unit 5 can not contact with the flue gas of high temperature, thereby avoids fuel injection unit 5 to be burnt out by high-temperature flue gas, prolongs the service life of fuel injection unit.
Through hole 4 is a plurality of for what distribute around spout 3a in the utility model, and as shown in Figure 1, a plurality of fuel injection units 5 are connected with fuel inlet 5a respectively, so that fuel enters a plurality of fuel injection units 5 through fuel inlet 5a.The axis of a plurality of through holes 4 forms different material spray angles respectively with between the axis of spout 3a, (only show two through holes 4 among the figure) as shown in Figure 3, the fuel (among Fig. 3 shown in the filled arrows) that is installed in fuel injection units 5 ejections in the through hole 4 crosses in a plurality of different spatial point with air (shown in Fig. 3 hollow core arrow), it is more even to make that fuel mixes with air, thereby improve efficiency of combustion greatly, also avoid in the flame set of organizations, thereby reduce NO
xThe discharge capacity of thing.
During actual the use, can fuel injection unit 5 be installed on the through hole 4 of different numbers and different material spray angles as required, remaining through hole 4 is sealed or one or more therein through hole on mounting points firelock 6, shown in Fig. 2 a, 2b; Can also as required through hole 4 be provided with different angles of inclination, thereby satisfy different burden requirements.
