Description

The invention relates to a burner for burning cocoa-burning plants, watered solid and liquid liquids, can be used in fuel-burning units, and is an improvement of the invention author, sv, No. 1125440.

The purpose of the invention is to provide the possibility of burning highly watered low-calorie solid fuels.

The drawing shows a nozzle longitudinal section.

The rotary fuel burner for watered fuel contains a central tube 2 and a coaxial shell 3 with a double-wall cone sprayer 4 at the end connected to the rotary drive and a screw swirl. 5 The central tube 2 is connected to the source. liquid fuel and rigidly fastened to the inner wall L of the atomizer 4, oriented with a large base towards the furnace space, and the inter-wall gap 7 of the atomizer 4 is connected to the watered solid fuel supply system and through the gap 8 between the central tube 2 and the shell 3 in which a swirler 5 is mounted, mounted on the central tube 2, the outer wall 9 of the atomizer 4 being rotatably mounted with respect to the shell 3; Inen with its inner wall 6 through the pipes 10, forming channels for the primary air. A gas collector 11 is provided for supplying the combustible gas to the combustion zone. At the outlet and the central pipe 2, a racket is installed 12, the Nozzle additionally contains a perforated conical drum enclosed in the housing 13

14 provided at the inlet with a feeder 15J oriented with a larger base towards the actuator 16 and connected with a smaller base to the shell 3, the drum 14 being connected to the actuator 16 via a multiplier 17o To remove fluid in the casing 13 from the larger base there is a nozzle 18,

The nozzle works in the following way.

The viscous liquid fuel is supplied to the centrifugal pipe 2, is deflected by the divider 12 to the inner wall 6 of the atomizer 4, and due to centrifugal forces moves to its end edge, from which it separates as a thin liquid shroud, mixing with the primary air, supplied through nozzles 10. Strongly watered solid fuel is supplied by the feeder 15 to the cavity of the perforated cone drum 14, where it is released from the liquid removed through the perforation into the gap between the drum 14 and the pig 13 and then through pipe 18, by means of a screw vortex 5 fixed on the central pipe 2, the fuel is transferred to the inter-wall gap 7 of the sprayer 4, in which due to centrifugal forces it is supplied to the end edge of the spray wall 9 of the sprayer 4 and sprayed at the outlet from it secondary air supplied from a channel formed by KopnjrcoM 1 and a spray 4, Combustion pipe 11 is supplied with combustible gas, which in the combustion zone of the fire chamber is mixed with air, water, solid fuel and viscous liquid fuel, and forms torch formations.
