-WATER BOILER Russian patent published in 2004 - IPC

Abstract RU 2230261 C2

FIELD: water heating systems; heat-power engineering. SUBSTANCE: proposed boiler includes furnace with side, ceiling and bent water walls, common discharge header located at the top of furnace and common discharge header located at the bottom of furnace and convection part formed from tube stacks separated by baffles made from heat-resistant material with lower dispensing and upper collecting headers; dispensing headers are connected to common supply header and collecting headers are connected to common discharge header located at the bottom of furnace. Tubes of bent water wall are perpendicular relative to one another forming ceiling water wall changing to rear water wall. Furnace is provided with additional water wall made from bent tubes and connected to common discharge header through collecting header at the top and to common discharge header at the bottom which is also connected with one of upper collecting headers of convection part. EFFECT: enhanced efficiency due to intensification of heat exchange process; improved circulation of flue gases and water; enhanced reliability and maintainability. 4 cl, 3 dwg
