Description

Biomass burner

Technical field

The present invention relates to a kind of biomass burner, belong to the combustion apparatus technical field.

Background technology

In recent years, the development and utilization of biomass energy more and more is subject to people's attention, and progressively obtains promotion and application.But at present in vast rural area, most of peasants are fuel with the agricultural crop straw still, make a fire with native kitchen range and cook, warm oneself.Higher because of the volatile matter content in the agricultural crop straw, when burning, can form black smoke because of combustion air is not enough and emerge, it is contaminated environment not only, and can damage health; Simultaneously, coal resources in China is very deficient, and operating medium small boiler is based on fire coal.Therefore, providing a kind of easy to use, environmental protection, efficient, energy-conservation biomass combustion device is the problem of the desired solution of people.

Summary of the invention

Technical problem to be solved by this invention provides a kind of biomass burner, and this burner structure is simple, fuel combustion is abundant, the thermal efficiency is high, uses health, convenience, environmental protection, efficient.

It is as follows to address the above problem the technical scheme that is adopted:

A kind of biomass burner, it comprises housing and fire grate, enclosure interior is a Bunker, the Bunker middle and lower part is the combustion chamber, and combustion chamber one side is established burner, and housing top is provided with charge door, sidewall is provided with air inlet and secondary air mouth, be provided with carriage in the housing on said secondary air mouth top, the two ends of this carriage are connected in the housing inboard, the two sides of carriage and inner walls from.

Above-mentioned biomass burner, establishing face between said carriage and level has inclination alpha, and inclination alpha is 0 °～30 °.

Above-mentioned biomass burner, said carriage are dull and stereotyped carriage or arc carriage, and its widest part is of a size of 1/12～1/2 of Bunker width or diameter.

Above-mentioned biomass burner, said dull and stereotyped carriage or arc carriage are provided with passage.

Above-mentioned biomass burner, said carriage are plane fire grate carriage or arc fire grate carriage, and its widest part is of a size of 1/12～1/2 of Bunker width or diameter.

Above-mentioned biomass burner, the jet-burner of said combustion chamber one side is provided with second combustion chamber, and second combustion chamber is provided with burner.

Above-mentioned biomass burner, said second combustion chamber is provided with air inlet three times.

Above-mentioned biomass burner, the enclosure interior border on said fire grate top and perisporium inboard, second combustion chamber are provided with heat-resisting heat-insulation layer.

Above-mentioned biomass burner, said charge door is provided with closing cap.

Configurable a plurality of carriages in the above-mentioned biomass burner, said housing, and corresponding configuration combustion chamber burner and secondary air mouth.

The present invention sets up horizontal carriage on top, combustion chamber, make the combustion chamber that enough big combustion space be arranged, Bunker around the combustion chamber can hold more biomass fuel, after lighting stove fire, the fuel gas that fuel generates enters second combustion chamber by the combustion chamber burner and burns away through high-temperature region and the mixed combustion of secondary wind.Fuel in the combustion chamber can be realized voluntarily the flow-type burning, is not adding under the situation of fuel by artificial the continuation, can carry out long-time continuous, stable work.The second combustion chamber configuration tertiary air import makes more efficient, the energy-conservation and environmental protection of the present invention.When need not when fire, fire can be sealed up, fire-sealing time can reach more than 12 hours.

The present invention collection just fires, anti-burning, backfire, horizontal combustion and destructive distillation, double-layer grate are one, have realized that the cyclic formula of fuel successively burns the combustion chamber in, and air distribution is reasonable, and very easy to use, environmental protection, health, efficiently are the ideal devices that utilizes biomass energy.Biomass burner provided by the present invention, configurable civil heating cooking function is used for domestic stove, also can be disposed at medium small boiler, is used for heating, oven dry or hot water, steam etc.The suitable fuel of this burner is wide, for example biomass solid shaping fuel (block, bar-shaped, graininess), wood chip, sawdust, cow dung, corncob, crops section shape stalk etc.
