利用变频调速调节鼓、引风机及炉排的转速可使系统更加稳定可靠，达到燃烧效率最高及节能的目标。１　风煤比寻优及送风调节当入炉煤量变化时，炉膛温度与送风量有一极值关系，对应的过剩空气系数为最佳值，这是计算机控制模型中采用的自寻优最佳风煤比调节规律的依据。为了提 The use of variable frequency speed regulation drum, fan and grate speed can make the system more stable and reliable, to achieve the highest combustion efficiency and energy saving goals. 1, air-fuel ratio optimization and air-conditioning When the coal into the furnace changes, the furnace temperature and air volume have an extreme value, the corresponding excess air coefficient is the best value, which is used in computer control model self-optimization The basis of the regulation of the best coal to air ratio. To mention
