乙炔和空气经乙炔、空气输入单元进入混合装置及脉冲罐，混合气体在混合装置

Acetylene and air enter the mixing device and pulse tank through the acetylene and air input unit. The <br>mixed gas is ignited at high frequency in the mixing device, deflagrates in the pulse tank, and expands sharply to produce high-temperature, high-speed airflow. The <br>airflow enters the furnace through the nozzle , And release energy in the form of impact kinetic energy, sound energy, and thermal energy. The <br>energy is subjected to multiple reflections from the heating surface tube bundle and furnace wall to diffuse the entire surface to be dedusted, so that the ash deposits are relaxed and fall off, so as to achieve the purpose of ash removal.

Acetylene and air enter the mixing device and pulse tank through acetylene and air input units, The mixed gas is ignited by high frequency in the mixing device, deflagrated in the pulse tank, and its volume expands sharply, producing high-temperature and high-speed airflow. The airflow enters the furnace through the nozzle and releases energy in the form of impact kinetic energy, acoustic energy and thermal energy. The energy is subjected to the hot surface tube bundle, and the furnace wall reflects many times to diffuse the whole surface to be deashed, which makes the accumulated ash relax and fall off, thus achieving the purpose of deashing.
