HEATING APPARATUS FOR CENTRAL HEAT SUPPLY SYSTEMS Russian patent published in 2006 - IPC F24H3/08 

FIELD: heat supply systems.

SUBSTANCE: heating apparatus comprises sections defined by the tubular heat exchanging members for heat agent and fining. The sections are additionally provided with the front low-temperature shields-circuits with vertical through passages and intermediate, bottom, top and back convective circuits with finning and swirlers. The tubular heat-exchange members are interconnected radially through the vertical plate that is provided with intermediate, bottom, top and assembled shields-circuits and back convective circuits. The swirlers are mounted in the inter-section junctions. The end section is provided with the branch pipe. The section is made of pig iron, steel, aluminum and their alloys, and the shields-circuits are made of a nonmetallic material.

EFFECT: enhanced efficiency.
