摘要：

A stirring wind-heating testing system was built. Two kinds of self-made heater were used as the research objects, and were started at the three different angular accelerations of 24.92, 14.66, 8.04 rad/s2 respectively. using dynamic torque tester and data acquisition instrument, the relevant data of the start-up phase of the heater was recorded, with which, the start-up performance of the heater was studied. The test results show that the torque of each heater requirement is directly proportional to angular acceleration, and the square of the rotational speed and the blade radius in the start-up phase. At the same time, the relation formula between torque and these factors are obtained; in addition, under the conditions of the full load operation, the start-up torque will achieve a peak, also, the greater the angular acceleration is, the higher the peak is. The natural wind must provide more than the torque of peak value, otherwise, the heaters will not start. © 2020, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
