Description

Solid fuel combustion chamber for combustor Technical Field The utility model relates to the technical field of combustion equipment, in particular to a solid fuel combustion chamber for a combustor. Background At present, in the field of solid fuel combustion, the problems of insufficient combustion caused by lack of oxygen in fuel, low heat utilization rate caused by not effectively utilizing and recycling heat generated by combustion, easiness in burning damage of a combustion cylinder due to long-time high-temperature ablation and the like exist in a combustion chamber for a traditional combustor. These drawbacks not only result in wasted fuel and increased use costs, but also create a large amount of insufficiently combusted contaminants, which makes it difficult to meet increasingly stringent environmental emissions standards, and there is a need for more efficient, durable solid fuel combustor designs. Through searching, the patent with the Chinese patent publication number of CN221763586U discloses a biomass solid fuel combustion chamber structure with high combustion efficiency. The technical scheme includes that the waste bin fixedly arranged at the bottom of the combustion box comprises a combustion box body, and further comprises a first combustion chamber, a second combustion chamber and a third combustion chamber which are arranged in the combustion box body from top to bottom, wherein the inner space of the second combustion chamber is larger than that of the first combustion chamber, the inner space of the third combustion chamber is larger than that of the second combustion chamber, and the depths of the first combustion chamber, the second combustion chamber and the third combustion chamber are equal. The utility model ensures the thorough combustion of fuel by arranging the plurality of combustion chambers, ensures the utilization rate of the fuel, avoids the waste of energy sources, and further, as the smoke and heat after combustion can rise upwards, the upper combustion chamber can preheat the fuel and air by means of the heat, the combustion temperature is improved, and meanwhile, the smaller upper combustion chamber can reduce the heat loss and keep the high temperature in the furnace. However, the device has the problems of effectively promoting the full combustion of fuel and effectively reducing the temperature of the combustion cylinder.
