Abstract
The present invention relates to a burner for a boiler using solid fuel such as wood pellets or the like, which are in the spotlight as biomass energy, and realizes a new combustion type, wherein fuel is transported using a screw circulating water inside and burnt in a predetermined section supplied with air (oxygen) by a blower. Therefore, it is possible to secure the durability of the screw even at the high temperature generated during the combustion, and complete simultaneous treatment of sludge and ashes. In addition, it is possible to largely reduce the size of the boiler using solid fuels, thereby simplifying the entire structure of the boiler, while promoting the reduction of manufacturing cost.
Claims12
A biomass solid fuel boiler comprising:
- a fuel supplier (10) adapted to supply solid fuel;
- a combustion device (11) adapted to burn the solid fuel;
- and
- a boiler body (12) adapted to heat water using combustion heat, wherein
- the combustion device (11) comprises:
- a combustion chamber (15) having a solid fuel supply hole (13) on a front side and a sludge/ash discharge hole (14) on a rear side, the solid fuel being burnt in the combustion chamber (15);
- a screw (16) arranged along and in parallel with the interior of the combustion chamber (15) and installed so as to rotate, the screw (16) comprising a hollow pipe, inside which water circulates so that the screw (16) can endure high temperature inside the combustion chamber, the screw (16) being adapted to both feed the solid fuel and discharge sludge and ash through a rotating operation;
- a driver (17) installed on a front portion of the combustion chamber (15) to rotate the screw (16);
- and
- an igniter (18) installed on a lateral portion of the combustion chamber (15) to ignite the solid fuel.

- a screw (16) arranged along and in parallel with the interior of the combustion chamber (15) and installed so as to rotate, the screw (16) comprising a hollow pipe, inside which fluid circulates to lower temperature inside the combustion chamber so that the screw (16) can endure high temperature, the screw (16) being adapted to both feed the solid fuel and discharge sludge and ash through a rotating operation;
- a driver (17) installed on a front portion of the combustion chamber (15) to rotate the screw (16);
- and
- an igniter (18) installed on a lateral portion of the combustion chamber (15) to ignite the solid fuel, and
- the boiler comprises a circulation fan or a compressor (30) adapted to push fluid into the hollow pipe-shaped screw (16) so that the fluid is introduced into the hollow pipe-shaped screw inside the combustion chamber.
