Horizontal fuel wood secondary air boiler
Technical field
The utility model relates to horizontal fuel wood boiler technology field, especially a kind ofly can make the clean-burning horizontal fuel wood boiler of fuel wood by secondary air.
Background technology
Boiler on the market is varied, and every kind structure structure is different, each has its oneself characteristics and deficiency.Wherein a kind of is horizontal fuel wood boiler, and horizontal fuel wood boiler generally includes body of heater, and the bottom is the combustion chamber in the body of heater, and top is heating clamber.Outer wall of combustion chamber below is provided with into material mouth, and fuel wood carries out air blast from advancing the material mouth and enter the combustion chamber and being placed on the fire grate of bottom, combustion chamber by an air inlet that is positioned at the fire grate below, makes fuel wood in the combustion chamber internal combustion.The outer wall of combustion chamber side also has peep hole, is convenient to the fuel wood combustion case in the combustion chamber is observed at any time.Be provided with water pipe in the heating clamber, flue stretches out the body of heater top through top of combustion chamber.This traditional horizontal fuel wood boiler structure is simple, and combination properties such as operability, the thermal efficiency and cost are relatively good, so still be widely used at present.But it still has a lot of deficiencies: be individual layer fire grate combustion system in the combustion chamber, fuel wood only can not fully burn through an air inlet air intake, thereby produces a large amount of black smokes and dust, has both wasted fuel wood, pollute air again, can not satisfy environmental requirement.
Summary of the invention
For solving the problems of the technologies described above, the utility model proposes and a kind ofly can make the clean-burning horizontal fuel wood boiler of fuel wood by secondary air, adopt the utility model, the fuel wood in the combustion chamber can be fully burned, and can not produce black smoke, environmental protection and energy saving.
The utility model is to adopt following technical scheme to realize:
A kind of horizontal fuel wood secondary air boiler, comprise body of heater, the body of heater bottom is the combustion chamber, top is heating clamber, bottom of furnace body is provided with the fire grate of placing fuel wood, the fire grate below is provided with air inlet one time, it is characterized in that: described outer wall of combustion chamber one side is provided with the secondary air device, the secondary air mouth of described secondary air device through being opened on the outer wall of combustion chamber is communicated with the combustion chamber, described secondary air device comprises blower fan and shelves the support of blower fan, the discharge pipe of blower fan connects the secondary air mouth, and described secondary air mouth is positioned between centre position, combustion chamber ± 30%.
Be provided with the coolant seal device between described discharge pipe and the secondary air mouth, described coolant seal device comprises the cooler bin of being located at the check valve in the discharge pipe and being positioned at the coolant seal device, fills cooling water in the described cooler bin.
Described secondary air mouth is 1-4, and the outer correspondence of each secondary air mouth is provided with a blower fan.
Described secondary air mouth is the peep hole that is arranged at outer wall of combustion chamber one side, and described peep hole is two, and the blower fan of corresponding setting with peep hole is two.
The blast of described blower fan is 1000-1500Pa.
Advantage of the present utility model is:
1, because the utility model adopts the outer wall of combustion chamber at existing horizontal fuel wood boiler to be provided with the secondary air device, when fuel wood burn to its secondary oxygen supply, thereby fuel wood is fully burnt, solved the problem of generation black smoke effectively, environmental protection and energy saving.
2, because adopting, the utility model between blower fan and secondary air mouth, is provided with the coolant seal device, check valve makes the unidirectional air-supply of blower fan, when blower fan cuts out, guarantees that the hot gas in the boiler can not enter blower fan, guaranteed that effectively blower fan is not damaged, prolonged blower fan service life; Be provided with cooler bin in the coolant seal device, cooling water cools off the hot gas that enters in the coolant seal case, thereby has guaranteed that further blower fan is injury-free, and prolong service life greatly.
3, because the utility model is opened in the outer wall of combustion chamber medium position with the secondary air mouth, when fuel wood burns, the position of secondary air mouth just is positioned at the medium position of flame usually, thereby the combustion efficiency that has guaranteed fuel wood is abundant more, thorough, further avoids the generation of black smoke.
4, since the utility model with the peep hole of boiler combustion chamber outer wall one side as the secondary air mouth, made full use of the existing structure of boiler, be issued to the purpose of this utility model in the situation of not damaging boiler structure; The number of secondary air mouth is 1-4, can be provided with flexibly according to actual needs, makes the oxygen supply of burning indoor secondary sufficient more, thereby further avoids the generation of black smoke, and it is more abundant to burn.
5, because the blast of the blower fan that the utility model adopts is 1000-1500pa, and the blower fan of this kind pressure can be matched with horizontal fuel wood boiler better, can reach effective air output is oxygen-supplying amount, can guarantee the safe in utilization of boiler effectively again.
