The boiler is an uprightly-deposited cylinder, is connected to the preheater, and has a conducting pipe and an exchange tube. The conducting pipe is deposited on and communicates with the boiler to enable the heat source to enter the boiler. The exchange tube is deposited in the boiler and has an exchange medium to exchange heat with the heat source in the boiler.

Abstract

An ash-collecting and exhaust device for a grain dryer has a body, a fan unit, and a driving unit. The body is a hollow barrel, and has an air inlet, an air outlet, and an internal surface being divergent adjacent to the air inlet. The fan unit is rotatably mounted in the body to enable external air to flow into the body via the air inlet and flow out of the body via the air outlet, and has an external surface being obliquely divergent to form an oblique passage between the body and the fan unit. The driving unit is securely mounted on the body, is connected to the fan unit to enable the fan unit to rotate relative to the body to guide the external air flowing into the body.

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.
