More Information
Summary:A gas-fired steam boiler, including multiple heat exchange tubes, an upper steam header, a lower steam header, a casing, a burner, a condenser, a chimney, and a controller. The heat exchange tubes are vertically arranged to form an annular tube row. A space enclosed by the annular tube row is configured as a furnace. Adjacent two heat exchange tubes are combined to form a gap channel evenly distributed along a circumferential direction. A width of the gap channel is 0.1-4 mm, and a circumferential length of the gap channel is 50-300 mm. A length of the gap channel along an axial direction of the heat exchange tube is the same as a length of the heat exchange tube.
