Be provided with the ring-type heat-transfer pipe in the described vaporizer, this heat-transfer pipe and breather pipe join, and have liquid-entering hole on the heat-transfer pipe; Described breather pipe has 5～10; Described combustion chamber assembly is made by the red copper material; Offer 5～20 burner ports on the described combustion tube, offer 10～30 overfolw holes on the vaporizer.

Owing to taked above-mentioned scheme, the advantage that the utility model is compared with prior art had is:

1, owing to be provided with inside and outside blast pipe, oxygen abundance in the combustion chamber, sufficient combustion, and burnt gas can upwards enter exhaust duct through burner hearth makes inner no pressure, security performance is good;

2,, be difficult for oxidation and stop up, and input duct is only by a liquid inlet port, compact conformation, convenient processing and maintenance because the combustion chamber assembly of this stove and accessory is to be made by the red copper material;

3, because inside and outside blast pipe is a cylindrical shell, make that firepower is concentrated and upthrust is big, increase work efficiency, save time and fuel; And igniting is fast, and this stove and accessory is an incendivity in 10 seconds.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model biological liquid fuel special furnace set;

Fig. 2 is the half sectional view of the combustion chamber assembly of the utility model biological liquid fuel special furnace set;

Fig. 3 is the vertical view of the combustion chamber assembly of the utility model biological liquid fuel special furnace set.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model biological liquid fuel special furnace set, form by grate 1, furnace shell 2, drainpipe 3, muff 4, igniting pin 6, combustion chamber assembly 7, wind gathering cover 8, burner hearth 9, stove circle 10 and exhaust duct 11, insulation material 5 is arranged in the muff 4, wind gathering cover 8 is installed at the middle part of muff 4; Combustion chamber assembly 7 is arranged in the wind gathering cover 8, and this combustion chamber assembly 7 is positioned at the bottom of burner hearth 9, and igniting pin 6 is placed on a side of combustion chamber assembly 7; On burner hearth 9, be mounted with stove circle 10, and the side of this burner hearth 9 has passage and links to each other with exhaust duct 11.
