The relationship be-tween the main& pipe pressure, steam drum pressure, steaming capacity, feedwater temperature and the speed of coal feeder, the opening of secondary air door are gotten by training the networks. 通过对网络的训练,建立了母管压力、汽包压力、锅炉蒸发量、锅炉给水温度等参数与给煤机转速和二次风门开度之间的关系。
Large amounts of foams are subject to come into being in the upper part of a coking drum in the delayed coker, which seriously influences the processing capacity and product quality. 在延迟焦化装置上,焦炭塔上部易形成大量的泡沫,严重影响焦化装置处理能力和产品质量。
Combining an example for 300 MW drum, the manufacturing quality control of high capacity boiler over 300 MW are analyzed. 以300MW锅筒为例,探讨和分析了300MW以上锅筒的制造质量控制。
Working mechanism of drum water level measuring device for large capacity utility boiler is introduced, and reason for different indicated values in local water gage, electrode water column gage and differential pressure water level meter are analyzed. 介绍大型电站锅炉锅筒水位测量设备的工作原理,分析研究了就地水位计、电接点水位计和差压水位计的指示值各不相同原因。
Finally, experimental verification and simulation both show that the two types of bionic non-smooth driving drum can increase the driving force and improve the transportation capacity of belt conveyor. 试验验证和仿真结果均表明:这两种仿生非光滑传动滚筒能增大驱动力,提高带式输送机的运输能力。
This method is simple and practical, and the safety of the drum is high, but the thickness of drum tends to conservative, the bearing capacity of the material has not been fully utilized. 该方法简单实用,安全性高,但通过该方法设计的焊接卷筒壁厚偏于保守,材料的承载能力没有被充分的利用。
When the structural size is magnified, the rotational inertia of drum is also increase just like the flywheel effect. It can keep the capacity, steady the rolling speed, boost the effect of coal and balance the load. 结构尺寸的增大,可提高滚筒的转动惯量,起到飞轮的作用,即贮存能量,稳定转速,增强滚筒的破煤能力和抗载荷能力等。
