Abstract:
A method for controlling supply of heat energy from a furnace to multiple dryers includes: determining a preset temperature, a preset humidity and a drying time for each of the dryers; calculating heat energy demand of each of the dryers according to the preset temperature, the preset humidity and the drying time of a respective one of the dryers, and calculating a fuel amount to be supplied to the furnace, and a volume of hot air to be supplied to each of the dryers; detecting a drying temperature in each of the dryers; and for each of the dryers, comparing the drying temperature and the preset temperature of the dryer, increasing the volume of hot air when the drying temperature is lower than the preset temperature, and decreasing the volume of hot air when the drying temperature is higher than the preset temperature.
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.
Abstract:
A furnace includes: a furnace housing; a perforated tray mounted in the furnace housing; and a stirring rod disposed rotatably on the perforated tray. The stirring rod has top and bottom ends, two opposite lateral ends, a middle portion, and opposite first and second portions, each of which extends from the middle portion to a respective one of the lateral ends. Each of the first and second portions has an inclined face that extends between the top and bottom ends of the stirring rod from the respective one of the lateral ends toward the middle portion of the stirring rod, that is inclined relative to the perforated tray, and that faces toward the perforated tray.
Abstract:
A feed hopper system includes: a hopper defining a chamber, the chamber having a lower portion; a stirring member; and a rotary feeding member disposed below the stirring member, mounted rotatably in the lower portion of the chamber of the hopper, and including a rotor that has first and second axial end portions. The rotary feeding member further includes a plurality of angularly spaced apart first blades that radiate from the first axial end portion of the rotor, and a plurality of angularly spaced apart second blades that radiate from the second axial end portion of the rotor. The first and second blades are alternately disposed.
Abstract:
A combustion system includes: a furnace housing defining a combustion chamber therein and having a gas outlet in fluid communication with the combustion chamber; a plenum housing surrounding and cooperating with the furnace housing to define a plenum chamber therebetween, and having an air inlet and an air outlet which are in fluid communication with the plenum chamber; and a heat exchanger housing disposed outwardly of the plenum housing and having an air inlet in fluid communication with the air outlet of the plenum housing, an air outlet, a gas inlet in fluid communication with the gas outlet of the furnace housing, and a gas outlet.

Abstract:
A heat exchange furnace includes a surrounding wall disposed around a combustion furnace unit so as to define an annular heat exchange space therebetween. Upright buffer plates divide the heat exchange space into a plurality of air chambers communicated with each other. Upper and lower gas-guiding members are connected respectively and fixedly to upper and lower ends of the surrounding wall. Conduit sets are disposed within the heat exchange space, and cooperate with the upper and lower gas-guiding members so as to constitute cooperatively at least one serpentine gas flow path disposed within the heat exchange space.

Abstract:
A furnace includes: a furnace housing defining a combustion chamber therein and having a top end section that is provided with an emergent stack which defines a gas-releasing channel in fluid communication with said combustion chamber; and a safety valve mounted in the gas-releasing channel and including a shaft that is secured to the emergent stack, and opposite first and second covering plates that are pivoted to the shaft so as to be rotatable relative to the shaft for closing and opening the gas-releasing channel.
Abstract:
A heat exchange furnace includes a combustion furnace module, a passageway module disposed around and connected removably to the combustion furnace module, and a gas-guiding unit including upper and lower guiding modules connected respectively to upper and lower ends of the passageway module. During assembly, the lower guiding module is first connected removably to the passageway module. Subsequently, the passageway module is sleeved removably on the combustion furnace module. Finally, the upper guiding module is connected removably to the passageway module.
