BURNER DEVICE

摘要

power engineering. SUBSTANCE: device may be used in heat-generating plants for keeping of controllable stable pulsating burning. Device has a body coupled to blast-air source. Confusion-diffusion head and fuel chamber shaped as hemisphere and coupled to tapered burning stabilizer are positioned at output of body along axis of the latter for longitudinal displacement. Fuel nozzles are arranged on fuel chamber along circular coordinate uniformity and at an angle to central axis of the body. Confusion-diffusion head is installed in the body with radial clearance which forms near-the-wall channel carrying high-speed flow of cooling air. Burning stabilizer is provided with hole for passage of air over entire tapered surface. In this case, angle at vertex of burning stabilizer tapered hood makes up 60-90 deg. EFFECT: enhanced fuel combustion efficiency and reliability of operation. 2 cl, 1 dwg
