Abstract:
A furnace includes: a furnace housing defining a combustion chamber therein, the combustion chamber having a round cross-section, the furnace housing being formed with at least two air inlets that are in fluid communication with the combustion chamber and that are angularly displaced from each other; and an air pipeline including at least two branch pipes, each of which is connected to a respective one of the air inlets of the furnace housing and each of which extends in a tangential direction relative to the cross-section of the combustion chamber.
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 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 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.
Abstract:
An incinerator includes: a furnace defining a combustion chamber and having a stack in fluid communication with the combustion chamber and having top and bottom open ends; and a flue gas-guiding mechanism including a flue gas conduit and a flue gas blower. The flue gas conduit has a generally L-shaped end portion extending into the stack and disposed between the top and bottom open ends of the stack. The flue gas blower is connected to the flue gas conduit for drawing flue gas out of the stack.
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 combustion system includes: a furnace housing; a heat exchanger including a heat exchanger housing and a tube-bundled structure that has a plurality of exhaust tubes, upper and lower plates, and an end cap, top ends of the exhaust tubes being fixed to the upper plate, bottom ends of the exhaust tubes being fixed to the lower plate, the upper plate being fixed to a top end of the heat exchanger housing, the exhaust tubes being thermally expandable in a downward direction; and a manifold interconnecting a gas outlet of the furnace housing and a gas inlet of the heat exchanger housing.
