摘要

FIELD: power engineering.SUBSTANCE: claimed invention relates to heat power engineering, namely to devices for heating, hot water preparation or heat supply for technological needs in household, production and other premises for various purposes, in which a central heating system is equipped. Heat exchanger of a solid fuel boiler with natural draft, characterized by the arrangement of heat exchanger tubes with welded joints, which are located exclusively outside the furnace of the boiler, while the upper furnace partition has a depth of about ¾ of the depth of the furnace and is hermetically connected to the side walls of the furnace and the back wall of the furnace and is located from the upper plane of the heat exchanger at a distance of about 1/6 of the total height of the heat exchanger, lower part has a depth of about ¾ of the furnace depth and is hermetically connected to the furnace side walls and furnace front wall, bottom partition being located from the lower plane of the upper partition at a distance of the order of 1/6 of the entire height of the heat exchanger.EFFECT: technical result is higher reliability and stability of the boiler.1 cl, 6 dwg
