Experimental device for stimulating burning of pulverized coal sprayed and blown by blast furnace

The utility model relates to an experimental device for stimulating the burning of pulverized coal sprayed and blown by a blast furnace. The experimental device comprises an air blower, a flow meter, a primary air pipe, a secondary air pipe, an air electric heater, a spiral coal feeder, a thermocouple, a primary air nozzle, a secondary air nozzle, a high-temperature furnace temperature controller, a high-temperature burning furnace, a gas collector, a vacuum pump, an infrared gas analyzer, a gravity dust collector, an induced draft fan, an inertia separator, a computer data line and a computer. The experimental device has the beneficial effects that pulverized coal can be more uniform and continuous in the experiment and conveying processes, the experimental results are more accurate and reliable, the pulverized coal burning rates under different conditions can be compared, and not only can the burning rate of single coal and mixed pulverized coal be obtained, but also the burning rate of the preheated pulverized coal can be obtained.
