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。

目前,大多数CFB锅炉采用了先进的床下点火技术:在左右一次风室各设置一支油枪;通常设置冷却风来把油枪出口温度控制在850°C以下;为了安全,应当设置点火油枪的火焰监视系统。
Secondary air volume control software
The secondary air shall ensure that the combustibles escaping from the dense phase area get further oxygen enriched combustion in the dilute phase area (suspension section).
The solution of uwntek system for secondary air control is:
(1) Ensure that the oxygen content of flue gas is within 3-5%;
(2) The total air volume including primary and secondary air shall match the material volume and meet the requirements of load instruction. And secondary air is required to realize double cross control: when adding load, add air first and then feed; During load reduction, reduce the material first and then the air.

Start the ignition control software
At present, most CFB boilers adopt advanced under bed ignition technology: an oil gun is set in the left and right primary air chambers respectively; Cooling air is usually set to control the outlet temperature of oil gun below 850 ° C; For safety, the flame monitoring system of ignition oil gun shall be set.
