FURNACE

摘要

FIELD: furnaces; various industries where burning of fuel is required to obtain high-temperature combustion products. SUBSTANCE: furnace has prismatic combustion chamber provided with blowing-in device located on end wall and blowing-in device located on side wall and directed tangentially. Device located on end wall is made in form of burner and device located on side wall is made in form of nozzle for feeding the recirculating gas. Nozzle is mounted in one of corners of furnace perpendicularly to wall on which it is located and in parallel with adjacent wall. Other corners of furnace are rounded-off. Located inside the furnace is partition provided with central hole. This partition is mounted perpendicularly to furnace axis on other side from nozzle relative to end wall. EFFECT: enhanced reliability at reduced amount of combustion products. 2 cl, 1 dwg
