Description

Combustor in a kind of biomass granule fuel furnace

Technical field

The utility model belongs to combustor in stove technical field more particularly to a kind of biomass granule fuel furnace.

Background technique

Coal stove is the common heating equipment of current people, with the development of economy, under the advocating and publicize of government, Energy-saving and emission-reduction, the concepts such as environmental protection have been rooted in the hearts of the people, and the product of renewable energy and many environmental protection and energy saving is in the whole society increasingly Widely promotion and application have gradually been washed in a pan using the stove of coal-fired class due to the problems such as discharge amount of pollution is big, efficiency of combustion is low Eliminate, biological particles be it is a kind of can replace coal-fired clean energy resource, have the advantages that high combustion efficiency, manufacturing cost are low etc., but It is, since a large amount of fugitive constituent can be generated when burning biomass fuel, in order to make biomass fuel full combustion, to improve burning effect Rate then needs to be transformed original coal stove, make biomass granule fuel carried out during burning it is secondary, supply three times Oxygen, to meet the needs of existing biomass granule fuel burning.Existing biomass granule fuel combustor is according to existing combustion The retrofit work of coal furnace (boiler etc.) is needed and is designed, in coal stove transformation process, stove (boiler) and combustor It places side by side, biomass granule fuel will burnt in external combustor burning cylinder roasting using corresponding technological means Burned flame laterally sprays into boiler in machine, to replace this improved furnace originally in boiler the case where burning coal Tool is had the following deficiencies: when in use first is that flowing up since hot-air density is small, and combustor combustion barrel is interior by shape Limitation, burning are in lateral-combustion state, burn extremely insufficient, meanwhile, the flame time laterally sprayed into is long, is easy to make to face Furnace wall burnt out prior to other positions；Second is that since traditional external combustion machine is laterally to spray into flame in stove, combustor Burning be in boiler exterior, thermal loss is big, and thermal energy conversion efficiency is lower, increases biomass granule fuel cost；Third is that The burning of traditional external combustion machine is carried out in combustion barrel, and combustion chamber volume is smaller, causes temperature excessively high, is easy to produce height Warm coking and blocking, fuel suppresses air feed mouth in addition, be easy to cause air feed insufficient, burns insufficient, generates coking and blocking again, and one Push-pull rods are arranged in a little producers, and coking block push-in is modified in the burner hearth of stove, coking and blocking problem is handled, but cause again by It is transformed in the burner hearth of stove and forms coking and blocking problem again, these coking and blockings had both hindered the abundant progress of burning, increased Fuel consumption, and increase cost of equipment maintenance and working time.

Specific embodiment

Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.

As shown in Figure 1 to Figure 3, the utility model provides combustor in a kind of biomass granule fuel furnace, including burner 1, It is equipped with fire bars 7 in the burner 1, feeder 4, igniter 3, coke removing appts 2, the air-supply are installed in the air supply tube 6 One end of pipe is connect with the burner 1, and the other end is equipped with air feed system 5 in the air supply tube 6, and the air feed system 5 includes Air devider 10 and blower 11.Using the technical solution of the utility model, burner 1 is protruded into burner hearth 15, on the surrounding inner wall of burner 1 Equipped with the ventilation hole being connected to air supply tube 6, biomass granule fuel is laterally sent into burner 1, under air feed system 5 passes through respectively Air duct 12 makes flame burn upwards air feed in burner 1, to make the burning direction of flame and the flow direction one of hot-air It causes, the resistance encountered when reducing flame combustion makes full combustion of fuel, and on the other hand, air feed system 5 also passes through air supply tube 6 It is combustion-supporting to four side inner wall air feed of burner, thus further make burning it is more abundant, reduce thermal energy transmitting loss, reduce fuel at This, improves efficiency of combustion, in addition, air feed system 5 in feeder also by air devider 10 to blowing, it is more to being formed in burner hearth 15 Secondary air feed is combustion-supporting, first is that the heating part in burner hearth 15 is made to have obtained cooling, goes out in air supply tube 6 second is that effectively preventing flame The phenomenon that now firing substantially increases efficiency of combustion, in addition, passing through the utility model third is that providing enough oxygen for burning The coke removing appts 2 of setting can clear up the charred ashes accumulated on fire bars 7, effectively prevent generating coking and blocking in burner 1 Phenomenon, and do not need to make to burn after unit stops just can be carried out de-coking operations, working time is saved for user, makes combustion apparatus Easy to maintain.

Further, peep hole tube channel 9, peep hole tube channel 9 are additionally provided in biomass granule fuel furnace in combustor One end be connected to the inner wall of the burner 1, the other end of peep hole tube channel 9 is along the length direction of air supply tube 6 to extension It stretches, so that user be made to be convenient for observing the combustion case inside burner 1 by peep hole tube channel 9, takes control measure in time.

As shown in figure 4, the coke removing appts 2 include deashing pawl 16 and pull rod 8, deashing pawl 16 is equipped with multiple deashing teeth 17, deashing tooth 17 is inserted into the fire bars 7, and one end of pull rod 8 is fixedly connected with deashing pawl 16, and the other end of pull rod 8 is along institute The length direction for stating air supply tube 6 extends outwardly.By back and forth pulling pull rod 8, deashing pawl 10 can be made to slide relative to fire bars 7, To carry out cleaning operation to coking, the ashes etc. in burner 1 in the case where stove does not need to shut down, labor is saved for user The dynamic time, make combustion apparatus easy to maintain.

Handle 18 is additionally provided on the pull rod 8, handle 18 is arranged in the outside of the air supply tube 6.Pass through 18 1 side of handle It is more convenient that face holds operator, and on the other hand, handle 18 can be heat-insulated, more comfortable when keeping operator hand-held.

Further, the deashing pawl 16 is parallel to the fire bars 7 and arranges.When operator being made to pull pull rod 8 every time in this way, Deashing pawl 10 keeps de-coking operations more thorough both with respect to vertical ground motions such as coking, ashes.

Further, the air supply tube 6 is made of heat-resistant steel, and extends the service life of air supply tube 6 in this way.

Further, burner 1 is set to the central location of burner hearth 15, leads to air devider 10 by the wind that blower 11 generates and distinguishes Air supply tube 6 is distributed to, due to being equipped with feeder 4 in air supply tube 6, the oxygen contained in the wind of submitting can be the burning in burner hearth 15 Combustion-supporting effect is played, on the other hand, other inert gases can be to each mechanical part in air supply tube 6 as lighted a fire in the wind of submitting Device 3, feeder 4 and 1 component of burner are cooled down, and are extended the service life of these components, are improved their durability.

The air feed system 5 further includes lower air duct 12, and lower air duct 12 is connected to the air devider 10.Use blower 11 The wind of submitting further distributes to lower air duct 12, and lower air duct 12 is the lower part air feed of fire bars 7 in burner hearth 15, on the one hand rises To combustion-supporting effect, so that 1 flame of burner is burnt upwards and keep consistent with the flow direction of hot-air, to make to fire It burns more abundant.
