Portion is jet end (9)；
The jet end (9) protrude into it is described ignite in chamber (4), and the jet end (9) is located at described chamber (4) central part of igniting
Position；The combustion gas injection direction of the jet end (9) and the flame direction of the flame jet (7) are oppositely arranged；The combustion gas is mended
Fill the second gas supply pipe (12) outside the other end connection of pipe (6).
5. a kind of heat conducting oil boiler of double fuel gas supplies according to claim 4, it is characterised in that: further include and the combustion
Room (17) concentric shield tracheae (44) is burnt, one end of shield tracheae (44) is protruded into the combustion chamber (17)；The shield gas
Managing (44) is the heating resisting metal pipe structure that internal diameter is greater than combustion gas supplement pipe (6), and shield tracheae (44) sealing two ends are set
It sets；
The combustion gas supplement pipe (6) is concentric to pass through the shield tracheae (44), combustion gas supplement pipe (6) outer wall and the shield gas
Two symmetrical shims (16) are provided with along its length between pipe (44) inner wall, and two shims (16) are by the shield
Oil inlet passage (10) and oil discharge passage (3) are separated into the pipe of tracheae (44)；Two shims (16) are ignited close to described
One end hollow out of cone (14) is provided with via hole (18)；The via hole (18) is by the oil inlet passage (10) and oil discharge passage
(3) mutual conduction；The oil inlet passage (10) supplies far from the cold conduction oil outside one end conducting connection of the via hole (18)
Oil pipe (11)；The oil discharge passage (3) far from one end conducting of the via hole (18) connect the hot oil heating tube (1) into
Oily end (5)；Thermal conductivity hot oil efferent duct (24) are connected in the oil outlet (5.1) of the hot oil heating tube (1).
6. a kind of method of the heat conducting oil boiler of double fuel gas supplies, it is characterised in that:
Combustion air supply pipe (51) continuously supplies combustion air to combustion air manifold (56) under air blower effect, then
Flue gas shunting in combustion air manifold (56) into each combustion air heat exchanger tube (57), hot cigarette in heat exchange box (53) at
Heat exchanger tube (57) group of pencil heats, and the combustion air being then heated imported into combustion air manifold (56) jointly, in turn
The combustion air converged in combustion air manifold (56) imported into fuel burner nozzle (19) by hot combustion air conduit (20)
Air inlet end, the air imported in fuel burner nozzle (19) are excess air, and excessive combustion air makes to enter in combustion chamber (17)
Combustion air sufficiently with also balance partial oxidation after the gas reaction entered together, main gas supply pipe (21) is even at the same time
Continuing to fuel burner nozzle (19) and injects combustion gas, combustion air and combustion gas spray at flame jet (7) after converging in fuel burner nozzle,
The electronic lighter at flame jet (7) starts at this time, and jet flames is formed at flame jet (7)；At this time in front of flame by
To the blocking at cone (14) tip of igniting, flame is made to scatter in horn-like, and even flame is attached at the leading portion of cone-type spiral distribution
Heating tube (1) is advanced, and is heated to the heating tube of leading portion (1), and what it is due to injection is excessive combustion air, and gas consumption is rapid,
With flame circular cone bottom surface (14.2) position for advancing to cone (14) of igniting when flame intensity start to weaken；At this time
Second gas supply pipe (12) continuously supplements pipe (6) to combustion gas and supplies, and combustion gas supplements jet end (9) spray of pipe (6) from combustion gas
Out, it and sprays in the internal chamber of igniting (4) of cone (14) of igniting, the pure combustion gas of ejection encounters the cavity walls (8) of chamber of igniting (4) Cheng Bo afterwards
Wave-like rebound, since cavity temperature alreadys exceed ignition point, and intracavitary also a large amount of balance oxygen, combustion gas is in chamber of igniting (4)
It burns rapidly during rebound, form second of horn-like flame and is uniformly sprayed rapidly out of chamber of igniting (4), attached immediately
Advance in the back segment heating tube (1) of cone-type spiral distribution, and back segment heating tube (1) is heated, finally formed flue gas passes through row
Mouth (27) discharge；
The cold oil come out from heating equipment is continuously imported into shield tracheae (44) by cold conduction oil fuel feed pump (11) in above process
Pipe in oil inlet passage (10), then conduction oil flows at via hole (18) along oil inlet passage (10), in oil inlet passage (10)
Oil flow to oil discharge passage (3) by via hole (18), then conduction oil flows to heating tube from the other end of oil discharge passage (3)
(1) oil inlet end (5), during being somebody's turn to do, combustion gas supplement pipe (6) outer wall between oil discharge passage (3) and oil inlet passage (10) is led
Hot oil contact surrounds, and avoids combustion gas supplement pipe (6) outer wall and directly is caused just to reach before gas injection goes out in pipe by flame heating
Ignition point in turn results in after the pure combustion gas in combustion gas supplement pipe (6) sprays and detonation at once is caused to influence combustion uniformity, conduction oil
Conduction oil is heated during by heating tube (1), hot oil oil outlet stream of the conduction oil being then heated from heating tube (1)
Out, and by circulating pump heating equipment is flowed to, is thusly-formed circulation.
