BOILER WITH FORCED CIRCULATION Russian patent published in 2019 - IPC F24H1/12 F24H9/14 

FIELD: heating.

SUBSTANCE: invention relates to direct-flow steam and hot-water boilers. Forced circulation boiler comprises a furnace chamber made of screen tubes and a convective part located behind it. Convective part is made of several parallel arranged in vertical collectors interconnected from above and from below by horizontal pipes, and between them – horizontal finned or smooth tubes, interconnected in a zigzag manner through the bends, where one end of the snake is welded to one manifold, and the other – to another vertical header so that when the packages are in a row, pipes connected in a zigzag manner will be staggered relative to similar pipes of the next package, at that, the packages themselves are connected to each other also in a zigzag manner through the bends welded to vertical collectors. Invention is aimed at improvement of boiler repairability.

EFFECT: boiler with forced circulation is proposed.
