Introduction to Circulating Fluidized Bed Incinerator

From: FAQ | Date：2026/6/27 | Hit：

The circulating fluidized bed incinerator is centered on fluidized combustion technology, realizes uniform heat transfer relying on inert media such as quartz sand, and forms a boiling fluidized state of inert particles and crushed waste through high-pressure and large-air-volume blast at the furnace bottom to achieve rapid and full combustion of waste. The lower part of the furnace has excellent high temperature resistance, and a stable fluidized combustion bed layer can be formed with heat-carrying inert particles.

The equipment has strict requirements on incoming waste, which needs to be crushed to a particle size below 50mm in advance to ensure fluidization uniformity and avoid incomplete combustion caused by large-particle waste deposition at the furnace bottom. Its core advantages are extremely high combustion efficiency with an unburned material removal rate of only 1%; there are no mechanical moving parts in the furnace, so the equipment has strong wear resistance and durability and longer service life.

The technical shortcomings are prominent: strict restrictions on feeding particle size lead to cumbersome pretreatment procedures; it relies on high-pressure and large-air-volume air supply, resulting in extremely high power consumption and large ash output, which greatly increases the operating load of the rear flue gas purification system; the equipment has complex operation logic and high requirements for parameter regulation accuracy, requiring professional technicians for operation and maintenance with high labor and technical costs.
