暖风器是防止空气预热器冷端传热元件低温腐蚀和堵灰的重要辅机设备。固定式暖风器随着运行时间的增加,内部管壁的锈蚀和粘附灰尘会使其阻力增大,造成风机电耗的增加。而旋转式暖风器可以在机组运行中根据环境温度的变化改变换热片与风向的夹角,从而降低暖风器前后压差。满足暖风器在不同运行工况、不同季节都能降低送风阻力,实现送风系统稳定运行,节能效果显著。
The air heater is an important auxiliary equipment to prevent the low-temperature corrosion and ash plugging of the cold-side heat transfer element of the air preheater. Fixed heater With the increase of running time, the inner wall of the corrosion and adhesion of dust will increase its resistance, resulting in increased fan power consumption. The rotary heater can run in the unit according to changes in ambient temperature change the angle between the heat transfer sheet and the wind direction, thereby reducing the pressure before and after the heater. Meet the heater in different operating conditions, in different seasons can reduce the air supply resistance, the air supply system to achieve stable operation, energy-saving effect is remarkable.
