Pulverized Coal Burner for Boiler-ZOOMLINE MACHINERY

The pulverized coal flame can continue to burn stably in the combustion chamber, with sufficient combustion and high thermal efficiency. The damper can be adjusted steplessly remotely. The flame length and thickness can be adjusted in real time in the control room according to the actual working conditions to achieve the best heating effect.
