Abstract

A stirring control method is adapted for a combustion apparatus which includes a furnace for burning fuel material, and a stirring member rotatably disposed in the furnace for stirring the fuel material and ash resulting from burning of the fuel material. The stirring control method includes: controlling rotation of the stirring member at an initial rotational speed; determining whether a height of the fuel material reaches an upper detection range; generating an indication when the height of the fuel material reaches the upper detection range; determining whether the height of the fuel material reaches a lower detection range when the height of the fuel material does not reach the upper detection range; and controlling rotation of the stirring member at a rotational speed higher than the initial rotational speed when the height of the fuel material reaches the lower detection range.

Dependent claims

A stirring control method for a combustion apparatus, the combustion apparatus including a furnace for burning fuel material, and a stirring member rotatably disposed in the furnace for stirring the fuel material in the furnace and ash resulting from burning of the fuel material in the furnace, the stirring control method utilizing a stirring control device and comprising:

(A) configuring the stirring control device to control rotation of the stirring member at an initial rotational speed;
(B) configuring the stirring control device to determine whether a height of the fuel material in the furnace reaches an upper detection range;
(C) configuring the stirring control device to generate a first indication when the height of the fuel material in the furnace reaches the upper detection range;
(D) configuring the stirring control device to determine whether the height of the fuel material in the furnace reaches a lower detection range when the height of the fuel material in the furnace does not reach the upper detection range;
and
(E) configuring the stirring control device to control rotation of the stirring member at a first rotational speed higher than the initial rotational speed when the height of the fuel material in the furnace reaches the lower detection range.

A stirring control device for a combustion apparatus, the combustion apparatus including a furnace for burning fuel material, and a stirring member rotatably disposed in the furnace for stirring the fuel material in the furnace and ash resulting from burning of the fuel material in the furnace, said stirring control device comprising:

an upper detector to be disposed on the furnace for determining whether a height of the fuel material in the furnace reaches an upper detection range;
a lower detector to be disposed on the furnace for determining whether the height of the fuel material in the furnace reaches a lower detection range lower than the upper detection range;
and
a control module associated operably with said upper and lower detectors;
wherein said control module is configured to control generation of a first indication when the height of the fuel material in the furnace reaches the upper detection range, and to control rotation of the stirring member at a first rotational speed higher than an initial rotational speed when the height of the fuel material in the furnace reaches the lower detection range and does not reach the upper detection range.
