Abstract

A kind of powdery biomass burner, it comprises: a feeding system be made up of motor (1), hopper (2), screw(-type) feeder (3), material blanking tube (4), feed pipe (14); One exports by igniter (5), combustion chamber (7), high-temperature flue gas the combustion system that (8) form; One supply air system be made up of First air blower fan (12), First air airduct (13), and the secondary blast system that is made up of Secondary Air blower fan (11), Secondary Air airduct (10), Secondary Air rotary blade (9).The utility model can accelerate the burning velocity of powdery living beings and improve the efficiency of combustion of whole powdery living beings, increases the time that powdery living beings stop in combustion chamber, and burning is more abundant, and efficiency is higher.

Description

A kind of powdery biomass burner
Technical field
The utility model belongs to fuel combustion appliance technical field, is specifically related to a kind of powdery biomass burner.
Background technology
Current, the environmental pollution environment that let us has been survived that the burning of fossil fuel causes can't bear the heavy load, and energy-saving and emission-reduction task is still heavy.Living beings are the fourth-largest energy except coal, oil and natural gas, and are the reproducible energy.The living beings of arising at the historic moment because of energy-saving and emission-reduction substitute numerous coal-fired boiler reforms of coal combustion, have higher requirement to biomass burner; Meanwhile, the powdered rice hulls quantity produced because paddy is made rice is every year very large, in order to the Thorough combustion solving this kind of powdery living beings utilizes, reduces environmental pollution, realizes energy-saving and emission-reduction, be necessary to design corresponding burner.Existing burner, when designing for powdery biomass combustion, is considered inconsiderate to air with mixing of dusty fuel, only has and air and dusty fuel is fully mixed and by dusty fuel Thorough combustion, could improve efficiency of combustion, the growing amount of decreasing pollution thing.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the powdery biomass burner that a kind of efficiency of combustion is higher.
The purpose of this utility model realizes by following technical proposal:
One feeding system be made up of motor, hopper, screw(-type) feeder, material blanking tube, feed pipe;
One exports by igniter, combustion chamber, high-temperature flue gas the combustion system formed;
One supply air system be made up of First air blower fan, First air airduct;
The one secondary blast system be made up of Secondary Air blower fan, Secondary Air airduct, Secondary Air rotary blade; Wherein, First air airduct and feed pipe are connected, and are sleeved on feed pipe in the shell that Secondary Air rotary blade is arranged on combustion chamber.
The utility model is by the effect of Secondary Air rotary blade, formation eddy flow state is entered combustion chamber by Secondary Air, and mix fully with primary wind and powder mixture, and form the gas-particle two-phase fluid rotating and advance, entrainment the flue gas of backflow at high temperature under, powdery living beings are by rapid ignition, fiercely to mix fully because powdery living beings and air flow with eddy flow state, this will speed up the burning velocity of powdery living beings and improves the efficiency of combustion of whole powdery living beings, simultaneously, because gas-solid is that eddy flow advances, add the time that powdery living beings stop in combustion chamber, burn more abundant, efficiency is higher.Meanwhile, under the effect of rotary pneumatic fixed double phase flow, and under Dual-Phrase Distribution of Gas olid effect is entrainmented in backflow, Inner Wall of Combustion Chamber can not produce the harm such as coking.The high-temperature flue gas that final burning is formed and flame will pass through, and thermal-flame exports the working medium entered in regenerator volume's heating tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of powdery biomass burner that the utility model provides, it comprises: a feeding system be made up of motor 1, hopper 2, screw(-type) feeder 3, material blanking tube 4, feed pipe 14; One exports 8 combustion systems formed by igniter 5, combustion chamber 7, high-temperature flue gas; One supply air system be made up of First air blower fan 12, First air airduct 13, and the secondary blast system that is made up of Secondary Air blower fan 11, Secondary Air airduct 10, Secondary Air rotary blade 9; Wherein, First air airduct 13 and feed pipe 14 are connected, and Secondary Air rotary blade 9 is arranged on 6 li, the shell of combustion chamber and is sleeved on feed pipe 14.
During use, powdery living beings are inside hopper 2, screw(-type) feeder 3 is driven by motor 1, be admitted to material blanking tube 4, material blanking tube 4 and feed pipe 14 junction tilt along feedstock direction, so that under a feeding wind action, enter feed pipe 14 smoothly, powdery living beings mix with the First air that First air blower fan 12 is sent here in material blanking tube 4 outlet, and be admitted to combustion chamber 7 through the Geldart-D particle of First air and burn, a bell-mouthed diffusion angle is had at First air feed pipe 14 end, object allows powdery living beings spread come, fully mix with swirl flow air.The Secondary Air that Secondary Air blower fan 11 blasts enters Secondary Air rotary blade 9 after Secondary Air airduct 10, Secondary Air promotes Secondary Air rotary blade 9 and rotates, just eddy flow state is formed through Secondary Air rotary blade 9 wind out, fully ignition will be mixed with primary wind and powder mixture after entering combustion chamber 7, simultaneously, due under the effect of swirling eddy, it is exactly that swirl flow wind exports that high-temperature flue gas inside combustion chamber 7 will be entrainmented the burner root that strile-backs, heat entrained by high-temperature flue gas is by abundant preheating powdery living beings, accelerate its ablaze speed, and the final efficiency of combustion improving powdery living beings.Igniter 5 is extension type, combustion chamber 7 can be advanced or pulled out by combustion chamber 7, by handle, burner is advanced inside combustion chamber at time of ignition, after lighting powdery biomass combustion, just pulled out by handle and exit combustion chamber 7, avoid the outlet of igniter 5 to be burned and by entrainment backflow gas-particle two-phase fluid wearing and tearing bad, and affect air-flow entrainment reflux and weaken reflux airflow to preheating of fuel.
