Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
The energy-saving carbonization oven that the utility model is provided, it is shown in Figure 1, including combustion chamber 10 and be placed on combustion chamber 10
Carbonization chamber 3, the side wall of combustion chamber 10 is provided with charge door 23, primary combustion ventilating opening 5, is also slag notch, is set in combustion chamber 10
There is fire grate 14,3 points of carbonization chamber is inner barrel and outer barrel two parts, and interior bucket 26 is connected with combustion chamber 10 by circulation line 12.Burning
During charcoal, the fuel fill in combustion chamber 10, igniting starts primary combustion, after burning starts, fuel is filled up in combustion chamber 10, lights a fire
Burning, then closes charge door 23, and as the temperature in combustion chamber 10 is raised, the temperature of bucket 26 constantly rises in carbonization chamber 3,
When temperature reaches to a certain degree, the material of the inside is pyrolyzed under high temperature anaerobic or anaerobism, produces flammable volatilization gas, example
Such as, methane, ethane, carbon monoxide etc., also referred to as biomass imflammable gas, these biomass imflammable gas are in closed charing
In Indoor pail 26, entered in combustion chamber 10 by circulation line 12, due to persistently thering is oxygen to supply in combustion chamber 10, flammable life
Material gases burn herein, heat supply in aftercombustion room 10, maintain the high temperature in carbonization chamber, meanwhile, carbonize Indoor pail
26 also can continual generation imflammable gas, be transported to combustion chamber 10, form a secondary combustion of constantly heating of circulation
Burning process, when charing Indoor pail 26 no longer produces biomass imflammable gas, biomass through pyrolysis have been completed, and carbonization chamber 3 exists
To room temperature, now, charcoal is made slow cooling at room temperature, removes the interior bucket 26 in carbonization chamber 3, and charcoal is poured out.This reality
It is identical with the theory of combustion of cooking stove common in the art with new combustion chamber 10, but by once adding fuel, Neng Goushi
Existing second-time burning, is heated in burning starting, it is necessary to add fuel, with the biomass combustibility gas produced in carbonization chamber 3
The supplement of body, carries out second-time burning, and persistently carbonization chamber 3 can be heated, and can so substantially reduce the cost of fuel.Its
The structure of combustion chamber 10 and carbonization chamber 3 is also fairly simple, makes easy, and cost is relatively low, may be adapted to small-scale firing charcoal, family
It is also not high with the energy-saving carbonization oven cost that charcoal is fired in front yard.
Above-described embodiment is only most basic mode, in order to further improve the cyclic utilization rate of heat, is realized secondary
