Problems solved by technology

[0002] The existing feeding system in front of the furnace of the bagasse boiler is to discharge the material through the push-pull scraper device on the belt conveyor. After the bagasse enters the feeder, it is transported into the furnace through the feeding nozzle of the feeder for combustion. This is a traditional process with low conveying efficiency. At the same time, it is easy to cause bagasse to pile up in the feeding nozzle of the feeder, and then cause the bagasse to enter the furnace for combustion under the condition of piles. The piles of bagasse cannot be fully burned in the furnace. It greatly affects the combustion efficiency of the furnace. Since the bagasse cannot be fully burned, it will reduce the thermal efficiency of the boiler and increase the generation of nitrogen oxides during the combustion process and the increase in fuel costs.
