The specific embodiment
As shown in Figure 1, heat-conducting oil furnace is made up of oil oven main body 1, main chamber 15 and subsidiary combustion chamber 23.
The bottom of oil oven main body 1 connects vertical subsidiary combustion chamber 23; Subsidiary combustion chamber 23 is the secondary cavity 13 of the cylindrical shape of hollow; Secondary cavity 13 is made up of the flame retardant coating and the outer field insulating brick 14 of internal layer; Offer some tertiary air holes 12 of advancing on the secondary cavity 13, the axial inwall and secondary cavity 16 inwalls in tertiary air hole 12 are tangent.One side of subsidiary combustion chamber 23 is offered a passage.Tertiary air hole 12 is connected with tertiary-air pipe 21, connects blower fan by the fan interface pipe.Secondary cavity is provided with thermocouple 6.
Main chamber 15 is a heat-storage type burner, and burner is made up of base, main cavity 4, heat-insulation layer 5, igniter 17, feed pipe 19, secondary air channel 22, Gas Pipe 3, fire door 8, form 7 and explosion proof door 18.Main chamber 15 agent structures are fixed by base support.Main cavity 4 is hollow circle tube, and the accumbency setting is made by refractory material (like refractory brick), the outer wall parcel heat-insulation layer 5 (like diatomite insulating block) of main cavity.Main cavity 4 is provided with feed pipe 19, the axial inwall of this feed pipe 19 and the lateral cross section inwall of main chamber 9 tangent (like Fig. 3).The wall body of main cavity 4 is provided with air compartment 2.The right-hand member of main cavity is provided with a fire door 8, and is sealed by bell.Be positioned at the top of fire door, also be provided with a form 7, be used to observe the combustion case in the burner, the anomaly when in time finding burning.The axis direction of main chamber 9 and be positioned at left side place horizontally set one Gas Pipe 3 of main chamber, Gas Pipe 3 and main chamber's 9 concentric settings, this Gas Pipe is the direct piping of both ends open.The right-hand member of Gas Pipe 3 inserts and is built-in end (this built-in end and main chamber right side have certain distance) in main chamber 9 inside, and its left end extends outside the main chamber 9 and inserts in the passage of subsidiary combustion chamber 23.The outside of air compartment 2 connects secondary air channel 22, and the inlet of secondary air channel 22 connects ventilating regulator, and ventilating regulator can be chosen butterfly valve (not shown) etc.Two secondary air holes 10 are set, the axial inwall of secondary air hole 10 and the lateral cross section inwall of main chamber 9 tangent (like Fig. 4) between air compartment 2 and the main chamber 9.Main chamber is provided with igniter 17, when working first, utilizes coal gas ignition that the combustion chamber is risen 400 ℃, begins the whirlwind charging then.Main cavity also is provided with temperature detection device, can be thermocouple 6, is used for measuring the furnace temperature of combustion chamber, generally surpasses 1000 ℃ of instant alarmings.Open bell and just can conveniently be cleaning lime-ash in the combustion chamber.Base can make things convenient for the dismounting of burner and move.Explosion proof door is in order to prevent the burner hypertonia, when internal pressure of combustion chamber surpasses 0.01Mpa, opens the explosion proof door release pressure, can prevent superpressure and blasts and cause peril.Automatic removing dust mouth 11 connects star-like discharger and can be used for regularly the lime-ash of main chamber being discharged.
The course of work of heat-conducting oil furnace is following: igniter at first; After temperature reaches more than 400 ℃ in the main chamber; Biomass material is after crushed tangentially blown into main chamber from feed pipe by primary air, in main chamber through forming biological fuel gas and some living beings ashes (like silica and slaine etc.) after 1 to 2 second high temperature (900～1000 ℃) the gasification pyrolysis.In combustion process; Because a wind is that the tangential gets into the combustion chamber; Therefore can in columnar combustion chamber, form whirlwind; Under the centrifugal action of whirlwind, the grey separated of generation of burning also descends in the bottom of main chamber, and the clean biological fuel gas around main chamber's axis centre then gets in the subsidiary combustion chamber through Gas Pipe.Simultaneously, secondary air channel continues air-supply (auxiliary air) to air compartment, and gets into main chamber through the air-supply of secondary air hole tangential, forms whirlwind to replenish required oxygen in the main chamber, and the biomass material of incomplete combustion is fully burnt, and reaches high combustion utilization rate.Through burning after a while,, then can reach fusion point of ash and slagging scorification easily if the temperature in the main chamber surpasses 1000 ℃.After thermocouple detects too high temperature, reduce the air quantity that gets into air compartment with butterfly valve control, thereby reduce main chamber's amount of oxygen, be lower than 1000 ℃ to guarantee the burning indoor temperature.
When biological fuel gas gets into subsidiary combustion chamber,, form whirlwind, biological fuel gas is fully burnt, for heat-conducting oil furnace provides enough energy through the additional air (tertiary air) of sending in 12 tangentials, tertiary air hole.
