The specific embodiment
Come the utility model is carried out detailed description below in conjunction with accompanying drawing and specific embodiment.
The theory of combustion:
Highly organized combustion process is as much as possible near completing combustion, promptly organic exhaust gas in the burner hearth internal combustion rapidly and fully, thereby obtain higher efficiency of combustion.The definition of efficiency of combustion is:
η
r＝1-(η
1+η
2)
In the formula, η
1-----heat loss due to unburned gas, %
η
2-----heat loss due to combustibles in refuse, %
For completing combustion, need following condition:
1, sufficient and an amount of air: the primary condition of burning is airborne oxygen content, and this is the necessary condition of fuel completing combustion.Optimal air amount and fuel ratio will pass through calculating and many-sided combustion experiment is obtained, and oxygen content is decided by air quantity.Oxygen content is not enough, and it is insufficient to burn, and air capacity is excessive, can waste heat energy.The use experience of many tame waste gas combustion furnaces is told us: organic combustible concentration is controlled under the situation of LEL 25% in the waste gas; Reasonably air distribution and control; Make organic combustible can be in incinerator the abundant burning of safety, can realize saving fuel oil or combustion gas again.
2, temperature in the suitably high stove: furnace temperature height then burning velocity is fast, and burning also is tending towards abundant more.Show through scientific research: organic matter is under >=760 ℃ temperature, and its molecule is destroyed basically fully, and oxidation generates water and carbon dioxide.But improve furnace temperature excessively also is worthless, because of too high furnace temperature, can the performance requirement of body of heater material be improved, and higher furnace temperature needs more energy and keeps, and power consumption is also just many like this.Simultaneously, because combustion reaction is a kind of reversible reaction, too high furnace temperature can make positive reaction speed up on the one hand; Simultaneously back reaction (reduction reaction) is speeded up.The quickening of back reaction speed then means the more heat energy of meeting consumption rate, makes fuel combustion do idle work, because reduction reaction is an endothermic process; Because reduction reaction has been offset the effect of part positive reaction, can cause the incinerator clean-up effect to reduce, influence the flue gas qualified discharge.
3, enough time of staying: organic matter completing combustion needs certain hour.Organic combustible is meant that in the time of staying of burner hearth organic combustible is from getting into high-temperature burner hearth, to the time that this section of furnace outlet flow process is experienced.The time of staying of organic combustible in stove depends primarily on the volume of burner hearth, sectional area, burner hearth length and the flowing velocity of flue gas in burner hearth of burner hearth, and these are all relevant with the sectional area thermic load of the volume heat load of burner hearth and burner hearth.Reasonably chamber design is particularly crucial.Through evidence: the time of staying >=0.6s in high-temperature burner hearth is best.
In addition, the energy flow process of direct combustion thermal accumulating incinerator is like following description:
