Abstract
The invention discloses a biomass thermal oil furnace and belongs to the field of fuel-burning equipment. The thermal oil furnace comprises a furnace body, a burner and a conveyer apparatus. The burner comprises a baseboard, a burning chamber and a fire grate and a wind chamber which holds air. A wind hole which is communicated with the wind chamber is formed on the wall body of the cylindrical burning chamber. The air of the wind chamber is distributed into the burning room for burning so that the burning can be more abundant and the high temperature biomass smoke is produced.
Description
Technical field
The present invention relates to a kind of combustion apparatus, specifically relate to a kind of heat-conducting oil furnace of firing biomass fuel.
Background technology
Along with the minimizing day by day of fossil and the known proved reserves of fossil energy, traditional energy is accelerating the edge towards exhaustion.In order actively to deal with energy crisis at hand, people have found the regenerative resource that substitutes, and biomass energy is a kind of exceedingly beautiful energy of renewable, reusable edible.Just because of this, the exploitation of biomass fuel in recent years, recycling, produce and to have received unprecedented concern.The agriculture and forestry organic waste material that the raw material of biomass fuel is mainly got; inexhaustible; by a series of deep processing; usually produce biological particles or powder; change into biomass energy after both are burnt respectively and provide alternative energy source for industry; not only solve the processing problem of agriculture and forestry organic waste material, also reduced CO
2With pernicious gas to airborne release.
In biomass combustion equipment, heat-conducting oil furnace is a kind of heating plant, and it comprises body of heater and burner.Wherein, burner is because there is design defect in the structure of self, the incomplete combustion of biomass fuel, and the biomass flue gas temperature is not high, causes the heat transfer efficiency of heat-conducting oil furnace on the low side.
Summary of the invention
The problem that exists in order to solve prior art the invention provides the high biomass heat-conduction oil oven of a kind of efficiency of combustion.
In order to realize above purpose, technical scheme of the present invention is as follows: a kind of biomass heat-conduction oil oven, formed by body of heater, burner and conveying device, described burner comprises base plate, combustion chamber and fire grate, burner comprises that also one holds the air compartment of air, and the wall body of described columnar combustion chamber offers the wind hole that is communicated with air compartment.
Further, periphery, described combustion chamber is around a cylinder that is fixed on base plate, and cylinder internal face and outer wall of combustion chamber mask have a space as air compartment, air compartment opening part shutoff one seal.
Described air compartment by base plate, combustion chamber wall body, periphery, combustion chamber around a cylinder and the flange installed of top, combustion chamber consist of.
Described wind hole is comprised of the windward hole and the apoplexy hole that are positioned at fire grate top and the leeward hole that is positioned at the fire grate below.
The angle of the axial line in described apoplexy hole and the radial line of combustion chamber is 25～40 °.
The axial line in described leeward hole and the angle of horizontal direction are 10～30 °.
Compared with prior art, because burner has been set up air compartment, and offer the wind hole that is communicated with air compartment at the combustion chamber wall body, the air that makes air compartment is assigned to by the wind hole and participates in burning in the combustion chamber, makes burning more abundant, to produce the biomass flue gas of high temperature.

Fig. 2 is the structural representation of burner.
Fig. 3 is apoplexy hole layout drawing.
Below, in conjunction with most preferred embodiment, the present invention is further specifically described.
The specific embodiment
As shown in Figure 1, the biomass heat-conduction oil oven is comprised of conveying device 11, body of heater 13 and burner 12.
As shown in Figure 2, burner 12 is cylindrical generally, by base plate 1, combustion chamber 3, form as cylinder 4 and the flange 5 of heat-insulation layer.Combustion chamber 3 and cylinder 4 all are located on base plate 1.The overall diameter of combustion chamber is 1300mm, and the interior diameter of cylinder is 1800mm, has therefore formed the air compartment 7 that holds air.The bottom of combustion chamber 3 is provided with retort(-type) stoker assembly 2, and the opening on top is as exhanst gas outlet.The opening on cylinder 4 tops by flange 5 sealings, makes air compartment have airtight space.Biomass fuel (as biological particles) burns on retort(-type) stoker and produces biomass flue gas, and is more abundant producing the high-temperature biomass flue gas in order to make burning, and the sidewall of combustion chamber 3 offers the wind hole, is that the inner space, combustion chamber replenishes more required airs.The wind hole is comprised of windward hole 6, apoplexy hole 8 and leeward hole 9, and windward hole 6 is positioned at apart from 100mm place, exhanst gas outlet below, and apoplexy hole 8 is positioned at apart from fire grate 2 100mm places, top, and leeward hole 9 is positioned at fire grate 2 100mm places, below.Windward hole and apoplexy hole are all horizontally disposed, and the leeward hole is in tilted layout.Particularly, the axial line in leeward hole is from the horizontal by 20 ° of angles, and air outlet is towards the top.The quantity in windward hole is 4, and the quantity in apoplexy hole is 10, and the quantity in leeward hole is 6.
As shown in Figure 3, during combustion chambers burn, can form the flame kernel zone.The imaginary cylindrical 10 of the extended line of the axial line in apoplexy hole 8 and central area is tangent, is namely that apoplexy hole axial line becomes 35 ° of angles (in figure angle a place) to be advisable with the combustion chamber radial line, to form the cyclone type burning, is conducive to abundant burning.
The operation principle of heat-conducting oil furnace is as follows: biomass fuel is sent to retort(-type) stoker 2 by conveying device 11, and in combustion process, air enters air compartment from air inlet 14, by the wind hole to combustion chamber internal distribution air quantity.Provide the primary combustion required air by leeward hole 9, second-time burning required air with flame is provided by apoplexy hole 8, and under the effect of whirlwind, the burning of formation cyclone type, the biomass flue gas that produce this moment rises to smoke outlet, then provides tertiary air by windward hole 6, and tertiary air is conducive to the abundant burning of biomass ash, the final biomass flue gas that produces enters body of heater, carries out heat exchange with oily heat exchanger tube.
