Abstract

The paper presents numerical simulation on co-combustion of diesel fuel and pulverized coal in a small-sized furnace equipped with oil-steam burner. A comprehensive mathematical model is presented that describes heat and mass transfer in the burning and furnace apparatuses: diesel fuel evaporation under the steam jet impact, turbulent combustion of evaporated diesel, combustion of coal particles. Simulation demonstrated that the available combustion chamber with an oil-stream burner enables combustion of micronized coal and ensures stable operation for a broad range of coal flow rates. The recent results of numerical simulation can be used for designing small furnaces for flare-mode combustion of micronized coal.

小型炉内柴油与煤粉混合燃烧的模拟研究

本文对柴油与煤粉在小型燃油蒸汽燃烧器炉内共燃烧进行了数值模拟。建立了一个综合的数学模型，描述了燃烧装置和炉内的传热传质过程：柴油在蒸汽喷射作用下的蒸发，蒸发柴油的湍流燃烧，煤颗粒的燃烧。仿真结果表明，采用燃油流燃烧器的燃烧室能够实现微粉煤的燃烧，并保证在较大的煤流量范围内稳定运行。数值模拟的最新结果可用于设计微粉煤的火焰燃烧小炉。
