2O) molecular hydrogen/oxygen molar equivalent ratio is through the hydrogen and oxygen gas mixture of special equipment electrolysis generation." Blang's gas technology is introduced burning of coal is the important breakthrough of CCT technology at energy field.
A kind of Blang's gas fired coal combustion machine, comprise coal bucket elevator (1), air blast (2), traveling-grate stoker (3), coal-storing hopper (4), coal valve plate (5), base (6), lighting door (8), air register (9), spiral tapping machine (10), it is characterized in that being provided with Blang's gas generator (14) in a side of combustor, on generator (14) top water inlet pipe and valve (16) are housed, positive top is provided with ammeter (15), there is Blang's gas escape pipe (11) in the left side, be connected and installed with backfire controller (12) and hydrogen-oxygen mixer (13) between escape pipe (11) and Blang's gas generator (14), the pipeline of air blast (2) and Blang's gas escape pipe (11) are connected to air, the import that Blang's gas mixing bellows (7) are gone up or Blang's gas escape pipe (11) directly feeds air blast (2) with after air mixes again by pipeline and air, Blang's gas mixing bellows (7) connect.
The addition of above-mentioned Blang's gas is that the bubbling air amount is the one thousandth of intake; Hydrogen concentration in the Blang's gas that feeds is 20-80PPM; The pressure that feeds Blang's gas is 1.0-2.5g/cm
2
The voltage of the ammeter (15) on above-mentioned Blang's generator (14) is 24V, and electric current is 150-200A.
Blang's formula fired coal combustion machine, be on the basis of traditional fired coal combustion machine, to have set up Blang's generator 14, water inlet pipe and valve 16 are equipped with in the top of this equipment, the top in this device front is provided with ammeter 15, Blang's gas escape pipe 111 is arranged in its left side, between pipeline and the Blang's generator 14 backfire controller 12 has been installed, hydrogen-oxygen mixer 13.The water inlet pipe of Blang's generator 14 and valve 16 opened add the water energising, the Blang's gas that produces enters backfire controller 12 after mixing through hydrogen-oxygen mixer 13, with anti-backfire, Blang's gas of Blang's gas escape pipe 11 enters air then, in Blang's gas mixing bellows 7, through fully mixing, under the regulating and distributing of air register 9, enter the pre-burning section of traveling-grate stoker 3, burning zone, (also Blang's gas escape pipe 11 directly can be fed air blast 2 imports, mix with air) make the raw coal combustion heat release, supply and demand side uses, last traveling-grate stoker 3 enters the cooling zone, and the air of being sent into by air register (9) makes the cinder and the cooling of fire grate afterbody of burning, and cinder is slagged tap from spiral tapping machine 10.The growing amount of Blang's gas is to lean on the size of the ammeter 15 on Blang's generator 14 to realize, generally is adjusted in voltage 24V, in the electric current 150-200A scope.
3, beneficial effect
(1) after traditional fired coal combustion machine imports Blang's gas, contained reactive hydrogen in Blang's gas, the reaction speed that makes carbon granules, carbon monoxide, hydrocarbon in the tail gas be converted into carbon dioxide is accelerated, and the concentration of emission of carbon monoxide obviously descends, and reaches＜5mg/NM
3Far below national specified discharge standard.The oxious component of flue gas reduces greatly.
(2) excess air coefficient of traditional fired coal combustion machine is about 1.25-1.40, and the fired coal combustion machine excess air coefficient that adds Blang's gas reduces greatly, and the coefficient of excess air of Oil-combustion combusting machine of introducing Blang's gas can normal combustion during near ideal value.The fired coal combustion power traction go into Blang's gas also can be under the situation of lower excess air coefficient normal combustion.The minimizing of excess air coefficient, the in-fighting heat loss is little, and flue-gas temperature also improves greatly.According to test, flue-gas temperature can promote more than 50 ℃.
(3) the reactive hydrogen oxygen in Blang's gas is a kind of not only the cleaning but also the new forms of energy of safety, because the catalytic action of hydrogen makes flying dust, fully oxidation of carbon granules, the utilization rate of raw coal can improve more than 10% in the fired coal combustion machine.
(4) because making, the alternating temperature effect of reactive hydrogen the interior heat-resisting surface of wall glazing of combustor makes that heat-resisting body of wall is more firm.And reactive hydrogen produces impermeability to the metal surface to the fire grate parts time, thereby the hardware corrosion resistance of fire grate parts is strengthened, like this can the deferred maintenance time, reduce maintenance cost.
