CFB锅炉一次风至少发挥了4个方面的作用:
(1)流化状态的建立取决于一次风量;
(2)床温的高低受到一次风量变化的明显影响;
(3)床料在密相区内实现良好的流态化燃烧取决于一次风量;
(4)床压的高低受到一次风量一定程度的影响。
UWNTEK系统对于一次风控制的解决方案是:
(1)根据负荷指令来确保一次风量和给煤量匹配,并且实现双交叉燃烧控制,即加负荷时先加风后加煤,减负荷时先减煤后减风。
(2)采用专家智能控制系统软件小范围内调节床温(一般为风量的0-5%范围内),既确保锅炉稳定燃烧,又确保床温控制在850-950℃范围内。
二次风量控制软件
二次风要确保从密相区逸出的可燃物在稀相区(悬浮段)得到进一步的富氧燃烧。
UWNTEK系统对二次风控制的解决方案是:
(1) 确保烟气含氧量在3—5%范围内;
(2) 包括一、二次风在内的总风量应当和料量匹配,同时满足负荷指令的要求。并且要求二次风以实现双交叉控制:实现加负荷时先加风后加料;减负荷时先减料后减风。This hot edge melting machine uses centralized PLC as the control core, which greatly improves its stability. Fire water supply equipment is an important part of fire protection system, and fire inspection cabinet plays an important role and significance in ensuring fire safety management and realizing efficient and safe operation in fire engineering construction. Nowadays, there is a common problem in all kinds of fire water supply equipment: when a building fire occurs, a considerable number of fire pumps cannot start after receiving the start signal, delaying the time of fire extinguishing. The main reason for the above phenomenon is that the fire pump does not start when there is no disaster at ordinary times. In addition, the pump room environment is generally humid, and the pump shaft, impeller and shaft sleeve inside the fire pump are prone to rust death. In view of this situation, it is necessary to conduct periodic inspection on the fire pump to maintain
