BOILER Russian patent published in 2007 - IPC F22B21/34 F24H1/12 

FIELD: heat and power engineering, possible use for heating water.

SUBSTANCE: boiler contains boiling layer furnace, moving fire bar flat part with blowing zones positioned below it, rotary screen, side screens, scalloped screen, convective block. On side screen, accelerating duct is mounted, inside which mobile plate is installed, and in its lower part pneumatic casting is built in. In frontal part of lower branch of mobile fire bar flat part, frontal thickened part is installed. In back part of upper branch of mobile fire bar flat part, back thickened part is installed. Rotary screen is made of pipes with metallic plates, attached to pipes along whole length. Between scalloped screen and convective block, in its lower part, water-cooled beam is installed, back part of boiler is connected to direct-flow cyclone. Boiler contains a recirculation system, which is made in form of a pipeline and positioned between smoke exhauster and air duct.

EFFECT: increased efficiency of boiler, reduced atmosphere pollution, improved labor conditions, reduced economic costs of boiler operation, increased reliability of boiler operation.
