Abstract
The utility model provides a longitudinally arranged reverse burning energy-saving single boiler-barrel horizontal boiler. The boiler is provided with a boiler body which comprises an upper boiler barrel and a boiler furnace. The upper boiler barrel is arranged on the top portion of the boiler body. Two longitudinal collection tanks are respectively arranged on the left side and the right side of the bottom of the boiler body. The upper boiler body is connected with the two longitudinal collection tanks through an outer tube wall. A middle transverse collection tank is arranged below the middle of the upper boiler barrel. The boiler furnace is arranged between the middle transverse collection tank and the front end of the boiler body. The boiler furnace comprises an inner tube wall, an upper fire grate and a lower fire grate, wherein the inner tube wall is arranged between the upper boiler barrel and the two longitudinal collection tanks. Flue gas passes through an upper boiler furnace and the upper fire furnace and arrives at the lower fire furnace to form a first flue gas return channel. A second flue gas return channel is formed between the inner tube wall and the outer tube wall. A third flue gas return channel is formed by a plurality of heat exchange tubes which are arranged between a front smoke chamber and a rear smoke chamber in the upper boiler barrel. Due to the fact that a multilayer grate tube structure and a counter burning mode are adopted by the boiler and the walls of the boiler furnace are not made of refractory materials, a radiating heating surface in the space of the boiler furnace can be utilized to the maximum extent. Consequently, the weight of the boiler body is reduced and production efficiency is improved.
