Specific embodiment
The present invention will be further explained with reference to the accompanying drawing.
Such as the attached high energy efficiency steam generator shown in Fig. 3 with waste-heat recovery device of attached drawing 1-, include furnace body 1, burning
Device 2, smoke exhaust pipe 3 and waste-heat recovery device 4 below will be illustrated each component part:
Furnace body 1, interior to have burner hearth 11 and combustion chamber 15, the burner hearth 11 has the water inlet led to outside furnace body 1
12 and steam port 13 out；Burner hearth 11 accommodates water, and the water in burner hearth 11 becomes high-temperature steam from steam port 13 after being heated boiling
Output, water inlet 12 connects water source, for supplementing water into burner hearth 11 in time.The inside of the burner hearth 11 is arranged in combustion chamber 15
Lower portion, lower end have the channel of installation burner 2, and there is enough spaces to allow burner 2 by combustion gas at it for combustion chamber
Middle full combustion generates high-temperature flue gas；Combustion chamber can will burner 2 burn after high-temperature flue gas heat transfer to burner hearth 11 in.
Burner 2, the combustion head of burner 2 protrude into the combustion chamber 15；Burner 2 is used using combustion gas as combustion medium
It is passed through after premixing air fuel in proportion in combustion chamber 15 and carries out ignition, be the water heating in the burner hearth 11；Combustion
Burner 2 comes with air blower, and air blower is conducive to make combustion gas full combustion, is also beneficial to the flue gas row that the burning of burner 2 generates
Out.
Smoke exhaust pipe 3, the flue gas generated for discharging the burner 2；
Waste-heat recovery device 4 is installed in the burner hearth 11, setting the combustion chamber 15 and the smoke exhaust pipe 3 it
Between, and the access that may pass through in it with flue gas.
The waste-heat recovery device 4 includes that several first heat exchanger tubes 42, several second heat exchanger tubes 41 and collection divide device 43.Often
The upper end of the first heat exchanger tube of root 42 is docked and connected with the smoke exhaust pipe 3；The upper end closed of every second heat exchanger tube 41；Collection divides device 43
It is docked and connected simultaneously with the combustion chamber 15, the first heat exchanger tube 42 and the second heat exchanger tube 41.After collection divides device 43 to summarize flue gas
Redisperse is to each first heat exchanger tube 42 and each second heat-dissipating pipe 41.
It only include second heat exchanger tube 41 in this implementation, second heat exchanger tube 41 is relatively thick, is placed in the burner hearth 11
Center, all first heat exchanger tubes 42 around second heat exchanger tube 41 be distributed.First heat exchanger tube 42 includes pipe
Body 421 and the aluminium heater 422 being placed in the tube body 421, aluminium heater 422 include many aluminium flakes for absorbing in flue gas
Heat.
As shown in Fig. 6, flue gas summarizes to collection and divides device 43, it is most of it is straight ascend into the second heat exchanger tube 41, on flue gas
During rising to 41 top of the second heat exchanger tube, heat is absorbed and discharged into the water in burner hearth 11 by the second heat exchanger tube 41,
After flue gas rises to 41 top of the second heat exchanger tube, temperature, which reduces, to be fallen after rise to the bottom of the second heat exchanger tube 41, and with a part
Do not enter the second heat exchanger tube 41 flue gas enter the first heat exchanger tube 42, the low-temperature flue gas of falling with directly from collection divide on device 43
Flue gas liquidates, and can reconcile the two temperature to lower temperature, then the aluminium heater 422 in the first heat exchanger tube 42 absorbs cigarette again
Heat in gas simultaneously also discharges heat into the water in burner hearth 11, the abundant recycling of so achievable flue gas heat.
Further, several third heat exchanger tubes 5 being independently arranged are also equipped in the combustion chamber 15.The third heat exchange
Heat-absorbing medium 52 of the pipe 5 including heat exchange pipe body 51 and the appearance for being set to the heat pipe body 51.All thirds
Heat exchanger tube 5 is mounted on the inside of combustion chamber 15, and the both ends of every third heat exchanger tube 5 are connected to burner hearth 11, in burner hearth 11
Water can enter in third heat exchanger tube 5, and third heat exchanger tube 5 is directly drawn fuel gas buring in combustion chamber 15 by heat-absorbing medium 52 and generated
Heat, then transfer heat in the water in it, the setting of more third heat exchanger tubes 5 can effectively improve high temperature in combustion chamber 15
The area of heat transfer of water, effectively improves the thermal efficiency in flue gas and burner hearth 11；All third heat exchanger tubes 5 surround the burning
The combustion head of device 2 circumferentially array distribution.
In order to guarantee the safety of furnace body 1, prevents over-voltage from the danger such as explosion occur, be additionally provided on the furnace body 1 and lead to institute
State the safety relief valve 6 of burner hearth 11.
For the ease of observing the combustion position of burner 2, observation port 14, the observation are provided on the side wall of the furnace body 1
