High-Efficiency Biomass & Coal Boiler

Coal-fired (biomass) boilers can burn for a long time after filling coal once, and automatic control cycle heating does not require special personnel on duty. The boiler operation is worry-free and labor-saving. An automatic control device is added to automatically control the outlet water temperature and automatically stop setting the outlet water temperature. The combustion technology of reverse burning multi-return fireworks and self-winding is adopted. The flame burns from top to bottom and uses a draft fan to guide the flow direction. There are multiple returns up and down through the inner wall of the pipeline, and finally the smoke outlet is discharged. The temperature rises quickly and the thermal efficiency is good.
