More Information
Summary:The invention discloses a stable combustion burner containing a pre-pyrolysis chamber, which comprises the pre-pyrolysis chamber, an inner secondary air pipe, a wall air pipe, a flow guide piece and the like, in the process that pulverized coal and gas are mixed by the inner secondary air pipe and blown into the pre-pyrolysis chamber for pre-pyrolysis, the wall-attached air pipe operates at the same time, other gas is fed into the pre-pyrolysis chamber, and due to the existence of the flow guide piece, the combustion is stable, and the combustion efficiency is improved. The flow guide part can guide airflow of the wall-attached air pipe to be blown to the inner wall of the pre-pyrolysis chamber to form wall-attached air, so that pulverized coal on the inner wall of the pre-pyrolysis chamber is blown away, meanwhile, in consideration of arrangement of the inner secondary air pipe, the wall-attached air pipe and the central air pipe are coaxially arranged, and the wall-attached air pipe is arranged on the outer
