Continuous slag discharging device of biomass particle combustion furnace

Abstract

The invention relates to a continuous slag discharging device of a biomass particle combustion furnace. The continuous slag discharging device of the biomass particle combustion furnace comprises a rotary grate and a rotary slag pulverizing rod. The rotary grate is composed of a plurality of rotary cast iron grate bars. Graphite bearings are mounted at the two ends of each cast iron grate bar. The graphite bearings are fixed to the furnace wall of the bottom of the combustion furnace through masonry or pouring. The rotary slag pulverizing rod is fixed through high-temperature-resistant bearings which are mounted on the upper surface and the lower surface of a steel plate at the bottom of the combustion furnace. The rotary grate is driven by a first driving mechanism. The rotary slag pulverizing rod is driven by a second driving mechanism. The continuous slag discharging device of the biomass particle combustion furnace is simple in structure and reasonable in design; and in the biomass particle combustion process, ash slag is continuously discharged out of a combustion chamber of the combustion furnace and prevented from being accumulated on the rotary grate, and thus safe and efficient combustion is guaranteed.

Description

technical field [0001] The invention relates to a continuous slagging device for a biomass pellet combustion furnace, and belongs to the technical field of slagging for a combustion furnace. Background technique [0002] Biomass solid briquette fuel has the advantages of easy storage, convenient transportation, clean and environmental protection, and high combustion efficiency. It is one of the main directions for the development and utilization of biomass energy. However, due to the high content of K, Cl and other elements contained in straw-based biomass raw materials, the ash melting point of biomass solid molding fuel is low, and slagging is prone to occur during combustion. If the ash cannot be discharged from the combustion chamber in time and accumulates on the grate, it will block the ventilation holes of the grate, which will not only affect the thermal performance of the combustion equipment, but also endanger the safety of the combustion equipment, and become an o...

AI Technical Summary

Problems solved by technology

Small combustion furnaces or boilers generally use fixed grates because of their simple structure, low price, and easy use. However, the fixed grate is determined to be that sometimes the grate cannot discharge slag continuously, and it is easy to be blocked, which will damage the safe and efficient operation.
