Abstract

A biological fuel boiler employs nature circulation form with a drum, the flue is provided with a superheater and a convection banner typed heating surface, the end flue is provided with air preheater, it is characterized in that: the front wall of the boiler hearth is provided with a plurality of discharging windows with flexible inlet angle, and with the secondary wind pipe underneath, the burning device employs a scale-like endless grate. The utility model implements discharging windows with flexible inlet angle and the secondary wind pipe underneath, the scale-like endless grate makes the base for boiler suspending combustion and intensified combustion method, thereby ensures in time light up and burning of biological fuel, realizes high effect and clean burning of biological fuel, meanwhile realizes the comprehensive utilization of ash.

Description

A kind of biological mass-energy fuel boiler
Technical field
The utility model relates to a kind of boiler, especially refers to the boiler of biomass-burning energy fuel.
Background technology
The development and application of biomass energy has at present caused common concern, the combustion technology of prior biological mass-energy fuel mainly contains two big classes: a class is to adopt the recirculating fluidized bed form, with biological mass-energy fuel and coal multifuel combustion, ratio is difficult to realize the comprehensive utilization of lime-ash about 20%; Another kind of is to adopt water-cooling reciprocation stove grate grate firing mode, whole system cost height.
The content of utility model
The purpose of this utility model is to provide a kind of biological mass-energy fuel boiler of environmental protection and energy saving, can not only guarantee in time catching fire and burning of biological mass-energy fuel, has realized the high-efficiency cleaning burning of biological mass-energy fuel, and can realize the comprehensive utilization of lime-ash.
A kind of biological mass-energy fuel boiler provided by the utility model, this boiler adopts the Natural Circulation form that has drum, in flue, be furnished with superheater and convection current flag formula heating surface, back-end ductwork is furnished with air preheater, it is characterized in that: be furnished with the adjustable blanking port of some entrance angles at described boiler furnace antetheca, it has secondary wind airduct, and the combustion apparatus in the burner hearth adopts scale chain grate.
In above-mentioned biological mass-energy fuel boiler, back-end ductwork also is furnished with economizer.
Owing to adopted above-mentioned technical solution, the utility model is by setting up the adjustable blanking port of entrance angle and its secondary wind airduct of arranging down, and employing scale chain grate, thereby for the intensifying combustion mothod that forms boiler suspension combustion+grate firing lays the foundation, guaranteed in time catching fire and burning of biological mass-energy fuel, realize the high-efficiency cleaning burning of biological mass-energy fuel, and can realize the comprehensive utilization of lime-ash.
Description of drawings
To the description of the utility model biological mass-energy fuel boiler one embodiment, can further understand the purpose of this utility model, specific structural features and advantage by following in conjunction with its accompanying drawing.Wherein, accompanying drawing is:
Fig. 1 is the applied boiler structure schematic diagram of the utility model.
The specific embodiment
As shown in Figure 1, the applied boiler of the utility model adopts the Natural Circulation form that has drum 1.Burner hearth 2 adopts film water cold wall structure.Arrange evaporating heating surface 4 and superheater 5 in the flue 3, evaporating heating surface 4 adopts the arrangement form of flag formula heating surface, and superheater 5 adopts the hosepipe form.Economizer 6 and air preheater 7 are arranged in the back-end ductwork, and economizer 6 adopts light pipe hosepipe form, and air preheater 7 adopts horizontal light pipe form.
Fire grate 8 adopts scale chain grate, isobaric wind storehouse, and a wind of boiler enters burner hearth 2 after regulating by some groups little air doors that distribute along the fire grate length direction, and fuel drops on grate firing on the traveling-grate stoker, the requirement that can take into account burning and burn.
Be the adjustable angle formula at each blanking port 9, its below is a secondary air channel 10, and its effect is: (1) utilizes wind-force that fuel is sent into burner hearth; (2) by regulating, can make fuel being more evenly distributed on the fire grate width; (3) cooling charging aperture.
Flue gas rises in burner hearth and enters evaporating heating surface by smoke outlet window, and its arrangement form is respectively to arrange one group of flag formula heating surface at furnace outlet and superheater outlet.Flue gas enters economizer after by evaporating heating surface and superheater, enters air preheater then, discharges after last flue gas enters dust pelletizing system.
The combustion method of the suspension combustion+grate firing of biological mass-energy fuel boiler is:
At first, with in the form of sheets, the biological mass-energy fuel of graininess or powdery is through conveying equipment, by the even charging respectively of several charging apertures of stokehold;
Secondly, by the secondary wind that is arranged in the charging aperture below fuel is sent into burner hearth, and under the cooperation of a wind, carry out suspension combustion in the burner hearth;
Then, based on fuel characteristic and fired state are regulated primary and secondary air, guarantee the higher temperature levels of combustion zone, prolong the combustible and the time of staying of high-temperature flue gas in stove;
Again, in the process of suspension combustion, bigger fuel particle is fallen and is carried out grate firing on the fire grate, by adjusting to charging aperture angle and the air-supply of secondary wind, make that the fuel bed depth that drops on the fire grate is even, by adjusting, guarantee fully burning of fuel again fire grate wind air-supply next time.
It is to act as a fuel with biological mass-energy fuel that the utility model is applied to biological mass-energy fuel boiler, meets a kind of environmental protection and energy saving product of national regenerative resource strategy.
Need to prove: above only unrestricted the technical solution of the utility model in order to explanation, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and not breaking away from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
