Description
One, technical field
The utility model relates to small-sized atmospheric hot-water heating boiler, is specifically related to a kind of coal and becomes the direct combustion heat homogeneous solution-type reactor of gas.
Two, background technology
Coal becomes the direct burning boiler of gas and has cleaning, environmental protection, advantage efficiently, and is therefore easy to utilize.Chinese patent ZL01216228.0 discloses a kind of coal-fired gasification hot water all-in-one oven, and it is that the bottom of stove hall in furnace shell is provided with gas producer, is communicated with short tube between gas producer and the stove hall, and the short tube place is provided with ajutage.The intercalated water sleeve of mutual perforation is set between body of heater shell, stove hall housing, gas producer housing and the flue cavity.In this patented technology, the coal gas burner that short tube and ajutage constitute of giving vent to anger, its combustion efficiency is undesirable, and it is inhomogeneous to exist coal gas to mix with air, the inadequate defective of burning, flame is young in addition, and the flue heat exchange is insufficient, influences the thermal efficiency.
Three, summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, a kind of sufficient combustion to be provided, the direct combustion heat homogeneous solution-type reactor of coal change gas that the thermal efficiency is high.
A kind of coal of the utility model becomes the direct combustion heat homogeneous solution-type reactor of gas, comprise furnace shell, the stove hall, the heat exchange flue, mutual intercalated water sleeve and the gas producer that connects, described heat exchange flue and described gas producer are arranged in the furnace shell, be characterized in: described gas producer top is provided with vortex burner, described vortex burner is by the coal gas escape pipe, ajutage, mix compression, the escape pipe capping is formed, described mixed compression is arranged on the periphery of described escape pipe, notch upwards, described ajutage tangentially is communicated with the bottom of described mixed compression, described coal gas escape pipe is provided with inclination coal gas venthole and is communicated with described mixed compression, the air-flow rotation direction of described inclination coal gas venthole and described ajutage air-flow rotation direction are in the same way, fixedly install the lifting rod that stretches out described furnace shell in the described capping, on the described lifting rod positioner is set, described mixed compression upper space is described stove hall.
In the above-mentioned scheme, described heat exchange flue can be arranged on a side of described gas producer, and described heat exchange flue is tubular, the passage that overdoes is left in the periphery, and the top connects chimney, and the below is uncovered, in the tube heat exchange water pipe is set, between described heat exchange flue and the described stove hall deflector is set.
In the above-mentioned scheme, described lifting rod can be a hollow pipe, and described capping is provided with the inspecting hole corresponding with described hollow stem.
In the above-mentioned scheme, described positioner is on described furnace shell sliding sleeve to be set, and described lifting rod is arranged in the described sliding sleeve, on the described sliding sleeve clamping screw is set.
The utility model operation principle: during operate as normal, build capping, the coal gas that produces in the gas producer sprays from inclination coal gas venthole, enter mixed compression, the tangential air-supply of ajutage enters mixed compression, and coal gas and air fully mix the generation whirlwind, mixed compression is a flame jet, increased the sectional area of flame jet, cyclonic air flow produces whirlwind flame, at first washes away Lu Tang, pass through deflector then, flame enters the passage that overdoes, and washes away recuperative furnace gall bladder wall and furnace shell inwall, and the flame rotation downwards, uncovered ploughing under in the heat exchange flue tube from heat exchange flue below, multilayer heat exchange water pipe is passed in the wake flame rising then, discharges flue gas from chimney, finishes whole flow process.During truce, ajutage stops air feed, upwards draws lifting rod, and capping is opened in the location, and the flue gas that gas producer produces can overflow from the coal gas escape pipe, discharges from chimney.
The utility model advantage is: vortex burner mixes fully coal gas with air, combustion efficiency is good, thermal efficiency height, combustion cleaning; Side at gas producer is provided with the heat exchange flue, and the body of heater height is lowered, and compact conformation occupies little space, and boiler adaptability is strong.
