Ash deposition mechanism of shoe manufacturing waste combustion in a full-scale CFB boiler

A Survey on Intelligent Optimization Approaches to Boiler Combustion Optimization

“…Physical and chemical methods [5,[7][8][9][10][11][12][13][14] Numerical simulation [6,[15][16][17][18][19][20][21][22][23][24] Burner design optimization [25][26][27][28][29][30] Operating parameter maintained at 850−950 ℃, lower furnace temperature, effectively avoiding the slag melting phenomenon. By adding limestone to the combustion process, the ash contains high calcium content, which can be used to make raw materials for cement and make the combustion residue recycled.…”

Comprehensive Study on Particle–Wall Interactions: From Microscopic Parameters to Macroscopic Implications

“…One classic example where particle−wall collisions play a significant role is in the realm of combustion, especially concerning ash deposition on heat exchanger surfaces. 5−8 Ash deposition can reduce heat-transfer efficiency, 9 equipment surfaces corrosion, 10 and even cause operational shutdowns, 11 leading to increased maintenance costs and reduced system reliability.…”

“…Particle–wall collisions are a ubiquitous phenomenon, prevalent in lots of industrial and natural processes. − Understanding the dynamics of such collisions is pivotal, not only from a fundamental scientific viewpoint but also due to its vast range of practical applications. One classic example where particle–wall collisions play a significant role is in the realm of combustion, especially concerning ash deposition on heat exchanger surfaces. − Ash deposition can reduce heat-transfer efficiency, equipment surfaces corrosion, and even cause operational shutdowns, leading to increased maintenance costs and reduced system reliability.…”
