Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of Multifunction burner, be located at the interior below of boiler shell 1, boiler shell 1 top is provided with chimney, boiler shell 1 is provided with ash hole, above-mentioned same as the prior art, this does not give unnecessary details, the plain grate 2 that is characterised in that of the present utility model is provided with fresh air inlet, burner hearth plain grate 2 belows are provided with air compartment 3 one time, one side of an air compartment 3 is provided with the grey chamber 4 of combustion, opposite side is provided with secondary air chamber 5, secondary air chamber is isolated by ladder fire grate 6 and combustion chamber, ladder fire grate 6 is provided with fresh air inlet, ladder fire grate 6 becomes 40 degree angles with horizontal plane, ladder fire grate 6 tops are provided with Bunker 8, Bunker 8 lower ends are provided with discharging opening, discharging opening is equipped with blanking regulates plate 7, and air compartment 3 and secondary air chamber 5 can be independent settings in the utility model, also can be connected, fresh air inlet on the horizontal fire grate 2 in the utility model is vertical configuration, fresh air inlet on the ladder fire grate 6 is horizontal, and in addition, the utility model can be provided with coke outlet on the boiler shell 1 of 6 of horizontal fire grate 2 and ladder fire grates, with when fuel is coal, draw out the charred ashes piece that forms because of burning through coke outlet.
The utility model be utilize the particle diameter of biological particles little, the characteristics of easy fluidisation, change the angle of repose of biological particles by fluidized wind, realize the autofeed of biological particles, and in conjunction with the Boiling Combustion theory of fluidized bed furnace, the principle of ladder fire grate kitchen range, designed the Multifunction burner, fuel storage is in feed bin, regulate plate through blanking and enter precombustion chamber, in precombustion chamber, toasted and processes such as drying, destructive distillation, charing, the precombustion chamber bottom is provided with the ladder fire grate, and the ladder fire grate is secondary air chamber down; The angle of repose of various fuel is about 40-45 °, and for the particle that guarantees feed bin can enter ebullated bed smoothly, the employing of ladder fire grate becomes 40 ° angle with level; Have the wind hole on the ladder fire grate, wind hole direction is a horizontal direction, the ladder fire grate act as the support material, prevent the fuel secondary air chamber that bleeds, and send into the fluidized wind of horizontal direction to material, realize the auto-partition oxygen supply.
