Abstract
The invention relates to a single spiral air-duct-type biomass boiler, which comprises a furnace body, a burner and a fuel conveyor; the single spiral air-duct-type biomass boiler is characterized in that: the front end of a fuel tube is connected to a boiler combustion chamber, the terminal end of the fuel tube is connected to an air blower through an air blower connector, an air volume control valve is arranged at the position of the air blower connector, a fuel hopper is provided with a spiral propeller inside, a screw rod is connected to a speed adjusting motor through a belt pulley arranged on the top of the screw rod, a distributor is arranged on the inner upper part of the fuel hopper. The invention transfers biomass fuel which is processed into bar shape or coarse powder shape into the fuel hopper, transfers the biomass fuel into the fuel tube through the spiral propeller, the volume and speed of the fuel transferred into the combustion chamber are respectively controlled by the speed adjusting motor and the air blower, and the fuel is blown into the boiler combustion chamber by wind force, so as to form suspension burning. The single spiral air-duct-type biomass boiler has the advantages that grate bars, furnace grates or transmission mechanism for the furnace grate does not need to be designed, thus reducing manufacturing cost of the boiler; waste straws are adopted as reusable energy for fully utilization, thereby solving the current energy shortage, and environmental pollution problems.
Description
Technical field
The present invention relates to a kind of single spiral air-duct-type biomass boiler, belong to biomass boiler burner and conveying device technical field.
Background technology
When traditional boiler utilizes living beings to act as a fuel, be living beings to be pulverized after mixing-moulding-oven dry, the problem that the fuel after this moulding in use exists is: increased the process links of living beings in pulverizing-mixing-moulding-oven dry; And the biomass fuel unit price after this moulding is equivalent to the price of equal calorific capacity coal, tallerly in producing coal zone goes out coal price.Therefore, original biomass grain forming explained hereafter cost height, the user considers to be difficult to accept from economic angle, is unfavorable for applying.In addition, traditional biomass boiler need be provided with the transmission mechanism of fire bars, fire grate and fire grate etc., because this structure is limit, makes the manufacturing cost of boiler higher.
Summary of the invention
The present invention is directed to the problem of above-mentioned prior art existence and a kind of single spiral air-duct-type biomass boiler is provided, the speed that this boiler adopts single-screw propulsion plant transfer the fuel and air quantity control fuel to carry, the employed granular fuel of conventional boiler is changed into the fuel that time processing becomes section shape or meal shape, complicated procedure when having reduced biomass moulding, reduced the production cost of biomass fuel, change the combustion system of living beings and the mode of movement of fuel, reduced the manufacturing cost of boiler.
The technical scheme of single spiral air-duct-type biomass boiler of the present invention is as follows:
A kind of single spiral air-duct-type biomass boiler, comprise body of heater, burner, fuel conveyor, it is characterized in that: the front end of propellant bottle is connected with boiler furnace, the end of propellant bottle is connected with blower fan by fan interface, the fan interface place is provided with volume control damper, be provided with spiral pushing device in the fuel hopper, spiral pushing device is made up of screw rod and the blade that is installed on the screw rod, screw rod is connected with buncher by the belt pulley that the top is provided with, drive the adjustable screw propulsion plant by buncher and be rotated pusher work, the fuel hopper internal upper part is provided with tripper, also is provided with cover plate on the fuel hopper.
The different parts of above-mentioned boiler furnace a plurality of burners arranged in a crossed manner, vertical or horizontal boiler all can adopt this combustion system.
The present invention becomes the biomass fuel of section shape or meal shape to be sent in the fuel hopper time processing, by the spiral pushing device in the fuel hopper, biomass fuel is sent in the propellant bottle.The speed that amount that fuel is carried and fuel enter the combustion chamber is regulated control by buncher and blower fan respectively, by wind-force fuel is blown into boiler furnace, forms suspension combustion.
Advantage of the present invention and effect are as follows:
1. single spiral air-duct-type biomass boiler reasonable in design of the present invention is with the difference of conventional boiler: do not need to design the transmission mechanism of fire bars, fire grate and fire grate, therefore reduced the manufacturing cost of boiler; Stalk discarded in the agricultural production fully is used as the renewable sources of energy, can solves present energy shortage and environmental pollution problems.
2. on range of application, city and rural area in China, especially in, samll cities and towns and vast rural area, have the bigger potentiality of applying; On application, not only can be used for the steam boiler in the industrial production, and be more suitable for hot water and the boiler for domestic or the use of other burner of civil heating.
3. utilization of the present invention, make the biomass fuel cost well below coal/wet goods fuel, two kinds of units of fuel calorific capacitys that collect according to present stage compare, be lower than 50% of coal, be lower than 90% of oil, when using various living beings, do not need big raw material to stack the place, can take to process on the spot short distance transportation, the supply and demand mode of lot size stock.
