Embodiment Construction
[0013] The present invention will be further described below using the drawings and specific embodiments.
[0014] Referring to the figure, the solid fuel pneumatic conveying temperature raising method for controlling the content of ash and slag combustibles of the present invention, at room temperature, the solid fuel has a calorific value of 17540kJ / kg, a volatile matter of 11.7%, and a fixed carbon of 43.4%. The particles are sent from the feed hopper 1 to the screw coal feeder 2, and are transported to the conveying section 11 of the spouted bed burner 3 through the screw feeder 2; Combustion in the generator 6 produces flue gas with a pressure of 3000-8000pa and a temperature of 400-1000°C, which is sent to the delivery section 11 of the spouted bed burner 3, and after the spouted bed burner 3 burns stably, the flue gas mixer 5 is closed , the air at room temperature and the flue gas at 600-800°C are sent to the flue gas mixer 5 by the blower 4, and the oxygen content of ...
