Description
Technical field
The utility model relates to field of boilers, particularly a kind of biomass-burning steam boiler.
Background technology
Traditional coal-burning boiler is using non-renewable resources-coal as main fuel, and along with the development of modern industry, the degree of dependence of whole industry to coal is increasing, thus make coal resources be in a kind of state of petering out, finding new forms of energy replaces coal extremely urgent, and because the restriction of the factors such as system architecture and combustion system, substantially it is insufficient all to there is this fired coal combustion in present intimate all boilers, the problem that the thermal efficiency is low, and cannot overcome always, this not only causes the waste of coal, also because all contain element sulphur in common coal, thus make in the flue gas of boiler tail containing a large amount of sulphur, very serious to the pollution of air.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provides one can biomass burning coal, and sufficient combustion, the thermal efficiency is high, the biomass-burning steam boiler little to atmosphere pollution.
The utility model solves the technical scheme that its technical problem adopts: a kind of biomass-burning steam boiler, comprise main body, described body interior is provided with burner hearth, face arch, rear arch and steam boiler, described face arch and rear arch are separately positioned on burner hearth both sides, described steam boiler is arranged on above burner hearth, secondary wind inleting tube is provided with in described face arch, described secondary wind inleting tube two ends are communicated with steam boiler with burner hearth respectively, described body exterior is provided with feed hopper near the side of face arch, setting gauge is provided with in described feed hopper, the conveyer belt that material in feed hopper can be sent in burner hearth is provided with below described feed hopper and burner hearth.
In order to make fuel combustion abundant, and prevent fuel from entering in secondary wind inleting tube and blocking secondary wind inleting tube, described blast pipe two ends are provided with filter screen, described secondary wind inleting tube inside is provided with some baffle plates, described baffle plate one end is fixed on secondary air inside pipe wall, is provided with gap between the baffle plate other end and secondary air inside pipe wall.
Block secondary wind inleting tube after entering secondary wind inleting tube to prevent fuel, described two adjacent baffle plates are separately positioned on secondary air inside pipe wall both sides, and described baffle plate and secondary air inside pipe wall form the angle being less than 90 °.
In order to increase laser propagation effect, described conveyer belt outer surface is provided with sawtooth block.
In order to ensure the stability of fuel feed, described setting gauge is spiral kickoff device.
The beneficial effects of the utility model are: this biomass-burning steam boiler uses spiral kickoff device steady and continuous feed, in face arch, secondary wind inleting tube is set, add the intake in stove, improve efficiency of combustion, and living beings are renewable resources, sulfide content after burning is less, less to atmosphere pollution.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1-Figure 3, a kind of biomass-burning steam boiler of the present utility model, comprise main body 1, described main body 1 inside is provided with burner hearth 4, face arch 2, rear arch 6 and steam boiler 5, described face arch 2 and rear arch 6 are separately positioned on burner hearth 4 both sides, described steam boiler 5 is arranged on above burner hearth 4, secondary wind inleting tube 3 is provided with in described face arch 2, described secondary wind inleting tube 3 two ends are communicated with steam boiler 5 with burner hearth 4 respectively, the outside side near face arch 2 of described main body 1 is provided with feed hopper 10, setting gauge is provided with in described feed hopper 10, the conveyer belt 7 that material in feed hopper 10 can be sent in burner hearth 4 is provided with below described feed hopper 10 and burner hearth 4, conveyer belt 7 outer surface is provided with sawtooth block 8, setting gauge is spiral kickoff device.
In order to make fuel combustion abundant, and prevent fuel from entering in secondary wind inleting tube 3 and blocking secondary wind inleting tube 3, described secondary wind inleting tube 3 two ends are provided with filter screen, described secondary wind inleting tube 3 inside is provided with some baffle plates 9, described baffle plate 9 one end is fixed on secondary wind inleting tube 3 inwall, is provided with gap between baffle plate 9 other end and secondary wind inleting tube 3 inwall.
In order to prevent fuel from entering blocking secondary wind inleting tube 3 after secondary wind inleting tube 3, described two adjacent baffle plates 9 are separately positioned on secondary wind inleting tube 3 inwall both sides, and described baffle plate 9 forms with secondary wind inleting tube 3 inwall the angle being less than 90 °.
