METHOD OF PNEUMATIC TRANSPORTATION OF POWDER-LIKE MEDIUM FROM HOPPERS OF ASH COLLECTORS

摘要

FIELD: power engineering. ^ SUBSTANCE: proposed method of pneumatic transportation of powder-like medium from hoppers of ash collectors comes to delivery of powder-like medium from hoppers into transport pipeline through inlet valve and acting onto surface of inlet valve by pneumatic impulse to close valve by pneumatic impulse to close valve and shaft powder-like medium along transport pipeline under action of pneumatic impulse. When implementing the method, air flow of total volume forming said pneumatic impulse is divided into two parts executing preliminary action of smaller part of total volume onto surface of inlet valve and subsequent action of remaining volume of air onto powder-like medium along transport pipeline. Pneumatic impulse delivery frequency is chosen depending on value of impulse pressure in transport pipeline. ^ EFFECT: increased length of transportation lines. ^ 1 dwg
