次風(fēng)量控制軟件
二次風(fēng)要確保從密相區(qū)逸出的可燃物在稀相區(qū)（懸浮段）得到進(jìn)一步的富氧燃燒。
UWNTEK系統(tǒng)對(duì)二次風(fēng)控制的解決方案是：
（1） 確保煙氣含氧量在3—5%范圍內(nèi)；
（2） 包括一、二次風(fēng)在內(nèi)的總風(fēng)量應(yīng)當(dāng)和料量匹配，同時(shí)滿足負(fù)荷指令的要求。并且要求二次風(fēng)以實(shí)現(xiàn)雙交叉控制：實(shí)現(xiàn)加負(fù)荷時(shí)先加風(fēng)后加料；減負(fù)荷時(shí)先減料后減風(fēng)。

目前，大多數(shù)CFB鍋爐采用了先進(jìn)的床下點(diǎn)火技術(shù)：在左右一次風(fēng)室各設(shè)置一支油槍；通常設(shè)置冷卻風(fēng)來(lái)把油槍出口溫度控制在850°C以下；為了安全，應(yīng)當(dāng)設(shè)置點(diǎn)火油槍的火焰監(jiān)視系統(tǒng)。Primary air volume control software
The secondary air shall ensure that the combustibles escaping from the dense phase area can be 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 quantity and meet the requirements of load instruction. And the secondary air is required to realize double cross control: when the load is increased, the air is added first and then the material is added; During load reduction, the material shall be reduced first and then the air shall be reduced.
