Embodiment Construction

[0026] see figure 2 , figure 2 It is a large-scale horizontal internal combustion fire tube hot water boiler with an external smoke-water heat exchanger of the present invention. Depend on figure 2 It can be seen that the large-scale horizontal internal combustion fire tube hot water boiler with an external smoke-water heat exchanger in the present invention is mainly composed of a drum 1, a furnace 2, an ember chamber 3, a second return convection pipe 4, and a turning smoke chamber 5 and smoke-water heat exchanger 6 form. The heat exchange tube of the smoke-water heat exchanger adopts the third return convection smoke tube. The drum 1 is arranged horizontally, the furnace 2 and the second return convection pipe 4 are placed in the drum 1, the second return convection pipe 4 is placed under the furnace 2, the ember chamber 3, the turning smoke chamber 5 and the smoke The water heat exchanger is placed outside the drum 1, and the ember chamber 3 is placed on the rear si...

Abstract

The invention relates to a large horizontal internally fired fire-tube hot-water boiler with an external smoke-water heat exchanger. The large horizontal internally fired fire-tube hot-water boiler comprises a boiler barrel (1), a boiler furnace (2) and a second return convection smoke tube (4). The boiler barrel (1) is horizontally arranged, and the boiler furnace (2) and the second return convection smoke tube (4) are arranged in the boiler barrel (1). The large horizontal internally fired fire-tube hot-water boiler is characterized in that the second return convection smoke tube (4) is arranged below the boiler furnace (2), a burnout chamber (3), a corner smoke chamber (5) and the smoke-water heat exchanger (6) are arranged on the outside of the boiler barrel (1), heat exchange tubes of the smoke-water heat exchanger are third return convection smoke tubes, the burnout chamber (3) is arranged at the rear of the boiler barrel (1), a shell side of the burnout chamber (3) is communicated with the boiler furnace (2) and the second return convection smoke tube (4), the second return convection smoke tube (4) is communicated with the corner smoke chamber (5), and the corner smoke chamber (5) is communicated with the third return convection smoke tubes of the smoke-water heat exchanger. The large horizontal internally fired fire-tube hot-water boiler has the advantages that the horizontal internally fired fire-tube boiler is large and is modularized.

Description

technical field [0001] The invention relates to a horizontal internal combustion fire tube hot water boiler. It belongs to the technical field of heating equipment. Background technique [0002] Most of the horizontal fire tube boilers are quick-installed, with the advantages of small footprint, simple system, and convenient installation, and they occupy an important position in my country's industrial boilers. However, the output of such boilers generally does not exceed 20t / h (14MW) due to the structural restrictions in GB / T16508 "Strength Calculation of Boiler Shell and Drum Pressure Components". [0003] Horizontal boilers have incomparable advantages over water tube boilers due to their fast-installed structure, convenient transportation and installation methods. However, as the market demand for large-capacity horizontal boilers increases, horizontal boilers are developing in the direction of large drums and large furnaces. Boilers are pressure vessels. As the diame...
