单交叉限制燃烧控制是七十年代后期出现的一种较新型的燃烧控制系统。它兼顾了串列串级系统和并列串级系统的优点,具有较优良的控制性能,因此颇受关注。 一、系统的工作原理和特点 1.系统的工作原理 系统的原理如图1所示,它是在并列串级控制系统的基础上增加了一些附加功能而构成的。温度调节器TIC为主调节器,它的输出信号A同时送至燃料和空气两个副环控制回路。这两个副回路之间有一个交叉作用过程。对于燃料控制回路,送至低值选择器 Single-cross-limit combustion control is a relatively new type of combustion control system that emerged in the late 1970s. It takes into account the advantages of tandem cascade system and tandem cascade system, with better control performance, so much attention. First, the system works and features 1. System works The principle of the system shown in Figure 1, which is based on the parallel cascade control system adds some additional features and composition. TIC thermostat regulator for the main regulator, its output signal A sent to both fuel and air secondary loop control loop. There is a cross-over process between these two secondary circuits. For fuel control loop, send to low selector
