本文介绍了双床并联运行沸腾炉固体未完全燃烧损失的组成与其影响因素的试验研究结果。试验表明,在双床沸腾炉的我q_4损失中,飞灰未完全燃烧损失q_4fh与溢流渣未完全燃烧损失q_4yl相接近。在锅炉结构尺寸一定情况下,燃料的颗粒筛分特性、流化数、床层温度和悬浮段温度是影响燃烧效率的主要因素。
This paper presents the experimental results of the composition and its influencing factors of the incomplete combustion loss of a twin-boiler in parallel operation. The experiment shows that in the loss of q_4 in the double bed boiling furnace, the incomplete combustion loss q_4fh of the fly ash is close to the incomplete combustion loss q_4yl of the overflow slag. Under the condition of certain size of boiler structure, the characteristics of particle sifter, the number of fluidized bed, the temperature of bed and the temperature of suspension section are the main factors affecting the combustion efficiency.
