锅炉燃烧的煤种不稳定是影响锅炉热效率的一个重要因素。近年来,我们采取了人工配制混合煤供锅炉燃用的办法。由于混合煤的几个主要技术指标相对稳定,对于提高锅炉热效率有一定效果。本文就混合煤的掺合比例的确定,煤的颗粒度和水份的选择以及强化燃烧的措施谈点体会。一、混合煤的配合比例每台锅炉都有一个设计煤种及适应煤种。不同型号的锅炉对Q_(dw)~y、V~r、A~y、W~y及颗粒度
Boiler coal combustion instability is an important factor affecting the thermal efficiency of the boiler. In recent years, we have adopted a method of manually preparing mixed coal for boiler burning. As the main technical indicators of mixed coal are relatively stable, to improve the thermal efficiency of the boiler have a certain effect. In this paper, the mixing ratio of mixed coal to determine the degree of particle size and moisture of coal and the choice of measures to strengthen the talk about the combustion experience. First, the mix of mixed coal Each boiler has a design of coal and adapt to coal. Different types of boiler on the Q_ (dw) ~ y, V ~ r, A ~ y, W ~ y and particle size
