Cold experimental study of gas-solid separation of coal gas reburn low NOx burner.

Analyse the gas-solid separation efficiency and its influencing factors of coal gas in the technology of partially gasified coal gas reburn to reduce NO_x. Build a gas-solid separation cold test rig of coal gas, which matches with a 130 tons cold hearth, exam the impact of separator wind and carrier gas flow rate on gas-solid separation effect of material in the separation device. The results show that, when the intake flow rate of the bottom inlet v₁ is 10 m/s, and the flow velocity of the top inlet v₂ is 5 m/s, the separation efficiency of semi-coke is the highest, and the separation efficiency of volatile also achieves greater value, the volatile can be well separated from semi-coke.
