HOT-WATER BOILER Russian patent published in 2006 - IPC F24H1/12 

FIELD: water heating, applicable in heat power engineering.

SUBSTANCE: the boiler gas a brick-lined body installed on a foundation, heat-exchanging blocks consisting of heat-exchanging sections are located in the body, the heat-exchanging sections are located in the body, the heat-exchanging tubes of each section are connected to headers, as well as a distributing header with an inlet pipe connection and a built-in header with an outlet pipe connection. Two heat-exchanging units are installed in the body, each of them has at least two heat-exchanging sections, the headers of the unit sections are parallel with each other and with the plane of the foundation, the heat-exchanging sections of each heat-exchanging unit are inclined at an acute angle to the plane of the foundation, and the upper headers of the units are drawn together, one of the lower headers of each unit is connected to the distributing header, and one of the upper headers of each unit - to the built-in header. The upper and lower headers of the adjacent sections of each unit, except for those connected to the distributing and outlet headers, are connected to each other at least by one by pass tube.

EFFECT: enhanced heating capacity and efficiency of the boiler.
