Biomass heating furnace facilitating ash removal

The utility model relates to the related technical field of renewable energy sources, in particular to a biomass heating furnace convenient for ash removal, which comprises a boiler which is a combustion structure of the heating furnace, a flue fixedly connected above the boiler, an ash baffle fixedly connected to the top of the flue, a processing mechanism arranged on the side surface of the boiler and spaced from the boiler by a certain distance, and a valve, the valve is fixedly installed on the side face of the flue, and the guide pipe is fixedly connected between the valve and the processing mechanism. Air carrying ash enters the treatment mechanism through the flue and the guide pipe in sequence and makes contact with water in the treatment mechanism, the ash can be adsorbed by the water, mixed liquid becomes inorganic matter fertilizer, beneficial and soluble substances are dissolved in the water, and the utilization rate of the ash is increased; air carrying ash reaches the tail end of the guide pipe
