Further improvement as technique scheme:
Be positioned at lighting door is installed on shell;
Be positioned on base support is also installed, feeding motor is installed on described support;
Described shell becomes hollow cylinder body structure;
Described shell becomes hollow regular polygon structure;
On described the 4th pipeline, air-quantity adjusting valve is installed;
Described cover plate is installed on heat-insulation layer top by sealing ring;
The upper end face of described cover plate is concordant with end face on casing.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to make.By feeding motor and conveying worm, complete the automatic transport of biological particles, lighting door is in housing exterior, conveniently complete igniting, the setting of blower motor not only makes burning more prosperous, can also play the effect that prevents tempering, has improved the utilization rate of fuel, its running stability, completely, efficiency is high in burning, pollutes few.
