6. a kind of method of double combustion air supply-type boiler furnaces:
First combustion air supply pipe (20) continuously injects combustion air, at the same time, gas supply pipe to fuel burner nozzle (19) (21) excessive combustion gas continuously is injected to fuel burner nozzle (19), injecting excessive combustion gas fills the combustion air entered in combustion chamber (17) Point with after the gas reaction entered together and balance Some gases, at the same time；Combustion air and combustion gas converge in fuel burner nozzle It is sprayed at flame jet (7) after conjunction, the electronic lighter starting at flame jet (7), flame jet are formed at (7) at this time Jet flames；Blocking in front of flame by cone (14) tip of igniting at this time, makes flame scatter in horn-like, and even flame pastes The leading portion heating tube (1) for investing cone-type spiral distribution is advanced, and is heated to the heating tube of leading portion (1), and what it is due to injection is excessive Combustion gas, the oxygen consumption for entering combustion chamber is rapid, with the circular cone bottom surface for advancing to cone (14) of igniting of flame (14.2) flame intensity starts to weaken when position；
Continuously the heat exchanging chamber (40) into air preheat case (30) injects combustion air to the second combustion air supply pipe (33) at this time, As heat exchanging chamber (40) internal pressure increases to far more than combustion chamber (17) pressure, the list in combustion air ingress pipe (36) is opened To valve, the combustion air being preheated in heat exchanging chamber (40) is entered in combustion chamber (17) by combustion air ingress pipe (36), and The jet end (36.1) of combustion air ingress pipe (36) sprays in the internal chamber of igniting (4) of cone (14) of igniting, the combustion-supporting sky of ejection Gas encounters after the cavity walls of chamber of igniting (4) into wavy rebound, and since cavity temperature alreadys exceed ignition point, and intracavitary there are also a large amount of Balance combustion gas, balance high-temperature fuel gas meets in chamber of igniting (4) with high temperature combustion air at this time, and second of burning rapidly, shape It is uniformly sprayed rapidly at second of horn-like flame and out of chamber of igniting (4), second of the hearty flame formed immediately continues to paste The back segment heating tube (1) for investing cone-type spiral distribution is advanced, and is heated to back segment heating tube (1), and finally formed flue gas flows through Each heat exchange smoke pipe (38), respectively the air in heat exchange smoke pipe (38) heat exchanging chamber (40) is preheated, and finally imported into afflux jointly In chamber (37), and it is extraneous by smoke exhaust pipe (34) discharge；
The cold oil come out from heating equipment is continuously imported into heating tube (1) by cold conduction oil fuel feed pump (11) in above process Oil inlet end (5), conduction oil are heated by conduction oil during heating tube (1), and the conduction oil being then heated is from heating tube (1) hot oil oil outlet outflow, and heating equipment is flowed to by circulating pump, it is thusly-formed circulation.
