Embodiment Construction
[0014] The gas produced by the gas generator passes through the gas inlet 6, and the air generated by the blower passes through the gas distribution inlet 8 and enters the gas burner 7 at the same time. After the gas is ignited through the ignition hole 10, it heats the pulverized coal burner 5 to above 800°C and starts The coal is ground to 180 mesh coal powder by the coal pulverizer, and input into the pulverized coal burner 5 through the pulverized coal inlet 11, the pulverized coal is ignited and burns continuously in the pulverized coal burner 5, and the gas is always supplied to the pulverized coal burner 5 Heat, strong wind is injected through the pulverized coal air distribution inlet 12, which ensures the continuous combustion of low-priced coal pulverized coal, and at the same time the heat of gas combustion is also fully utilized. Gas, air, and pulverized coal are rotated, fully mixed and burned, prolonging the burning time, and pulverized coal is fully burned, and t...
