成都无缝钢管厂216加热炉燃烧控制系统由HOMAC-700系列微机与国内DDZ-Ⅲ型仪表配套组成。该加热炉各段温度控制采用温度、燃料、空气流量串级调节系统,实现偏差比例型交叉制约、解耦控制,减少了各段温度的相互干扰。系统投运后燃气单耗下降12％,提高成材率1％左右。
Chengdu Seamless Steel Tube Plant 216 heating furnace combustion control system consists of HOMAC-700 series of computers and domestic DDZ-Ⅲ-type instrumentation components. The temperature control of each section of the heating furnace adopts the cascade control system of temperature, fuel and air flow to realize the deviation proportional type cross-control and decoupling control and reduce the mutual interference of the temperature of each section. After the system is put into operation, the consumption of gas will drop by 12%, and the finished product rate will increase by about 1%.
