It was observed that there existed two burning modes for the thermoplastics, one is solid surface burning, the other is melt flow burning, which is controlled by the surface flame spread and the development of pool fire on the floor beneath the bottom of the lining respectively.
研究发现,热塑性材料存在固体表面燃烧(PMMA和PVC)与流动燃烧(PP,PE和PS)2种燃烧形式,其中固体表面燃烧受壁面火蔓延控制,流动燃烧受油池火控制;通过对热解机理的探讨发现热解机理是控制材料燃烧形式的主要因素;通过材料流动能力、油池火发展和热释放速率的比较发现,流动能力对流动燃烧的影响非常大,材料流动能力越好越不利于油池火的形成与发展,所能达到的火灾规模越小。
In a power plant,a 125 MW tangential firing boiler had the problems of unstable combustion,incapability of peak load regulation,lower hot air temperature and larger steam temperature difference between the two sides of reheater.
针对某电厂125 MW四角燃烧无烟煤锅炉运行时稳燃能力差,不具有调峰能力、热风温度低于设计值、再热器两侧气温偏差较大等问题,分析了问题产生的原因,对#2炉进行了改造,改造后进行了配风和锅炉效率试验。
The #2 boiler in Jiaozuo Power Plant is 670 ton per hour (tph) tangential firing boiler.
对于低挥发分的无烟煤,由于其着火温度较高,最主要的问题在于如何能使无烟煤快速的着火和稳定的燃烧,焦作电厂#2炉为670t/h四角燃烧无烟煤锅炉,在运行中存在着低负荷稳燃能力差、结渣严重等问题,针对以上问题,对锅炉进行了改造,使用哈尔滨工业大学的水平浓淡风煤粉燃烧器替代原有燃烧器,改造后没有出现过结渣问题,最低不投油负荷达到50%ECR。
