Abstract
The utility model relates to a burner which is particularly applicable for coal powder burning in a power station boiler, composed of a primary air passage, a secondary air passage, a joint of a cooling air passage, and a blunt body burning stabilizer or a cyclone. The utility model is characterized in that a small strand primary air passage, an oil gun and the cooling air passage pass through the blunt body burning stabilizer or the cyclone zone to be communicated with a return flow zone directly.
Description
The utility model relates to a kind of burner, is specially adapted to power boiler breeze burning occasion.
Existing DC burner China's patent " a kind of coal burner " with bluff body (ZL90108583.9) and " vortex burner " (ZL95200375.9), they send the shallow bid primary wind and powder into the recirculating zone, strengthened burning, but in ature of coal better and might form coking during high load capacity.Simultaneously, the fuel-economizing potentiality of above-mentioned two kinds of burners when startup and peak are not given full play of as yet.
At the shortcoming that above-mentioned prior art exists, the utility model provides a kind of shallow bid primary wind and powder, combustion-supporting oil and one cold wind is combined, and can send into the recirculating zone as required stage by stage, finishes the multipurpose burner of multiple function.
The utility model is implemented (Fig. 1) by following technical measures: it is made of air channel 2, secondary air duct 1, cold air duct interface 5 and a baffle flame-holder 6 or cyclone, air channel 3 of shallow bid, oil gun 4 and cold air duct 5 pass baffle flame-holder 6 or cyclone and directly enter the recirculating zone.
Description of drawings is as follows:
Accompanying drawing 1 novel burner structure principle chart
Advantage of the present utility model: after (one) shallow bid powder gas and combustion-supporting oil are sent into the recirculating zone in the lump, Formation is then lighted lighting step by step of a wind main flow by it by combustion-supporting oil drop combustion shallow bid wind powder Cheng Dada has accelerated ignition procedures, thereby saves combustion-supporting oil. (2) better when coal, load Height occur coking or burner burn out may the time, one cold wind is introduced recirculating zone, makes the recirculating zone Cooling, after move, reduction burning prevents the formation of coking, thereby realizes a kind of burner Multi-purpose purpose.
The utility model is further specified as follows below in conjunction with accompanying drawing:
It is made of air channel 2, secondary air duct 1, cold air duct interface 5 and a baffle flame-holder 6, air channel 3 of shallow bid is set, pass baffle flame-holder 6 and directly lead to the recirculating zone, cold air duct is communicated with by air channel 3 of cold air duct interface 5 and shallow bid, in air channel 3 of shallow bid oil gun 4 is set.
Claims (1)
1, a kind of novel burner, it is made of an air channel (2), secondary air duct (1), cold air duct interface (5) and baffle flame-holder (6) or turbulent burner, it is characterized by that an air channel of shallow bid (3), oil gun (4) and cold air duct (5) pass bluff body burner (6) or cyclone directly enters the recirculating zone.
