Problems solved by technology

[0002] In the prior art, the technical solution closest to this application is the horizontal boiler in use. The water wall of a conventional horizontal boiler is composed of a row of densely distributed water wall tubes. The role of the middle and lower parts of this water wall tube is Obvious, but the role of the middle and upper parts is not good
Moreover, the temperature of the conventional horizontal boiler at the back of the furnace and the smoke pipe is too high, and the heat exchange area is insufficient, resulting in a large amount of waste of energy, which is the deficiency of the existing technology

Embodiment Construction

[0008] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0009] It can be seen from the accompanying drawings that the horizontal boiler of this scheme is a three-pass horizontal boiler, including a furnace body 9 and a grate 1 in the furnace body 9, a furnace 2, a water wall and a horizontal drum 7. There are second return smoke pipe 4 and third return smoke pipe 5 inside the drum 7, and a front smoke box 8 and a flue exhaust duct are arranged outside the horizontal drum 7. The water-cooled wall described in this plan is composed of 1-5 branches. A group of water-cooled wall tubes 3 and 1-5 convection tubes 6 as a group are spaced apart from each other. The spacers form the water walls. The convection tubes 6 are parallel to the water-cooled wall tubes 3 at the bottom of the furnace 2, and each group of convection tubes is bent at an ang...

Abstract

The invention provides a technical scheme of a horizontal boiler. The horizontal boiler comprises a boiler body, and a fire grate, a hearth, a water cooling wall and a horizontal drum in the boiler body. The horizontal drum is internally provided with a smoke tube. A front smoke box and a smoke exhaust channel are arranged outside the horizontal drum. The horizontal boiler is characterized in that the water cooling wall is formed by 1-5 water cooling wall pipes as a group and 1-5 convection tubes as a group at intervals. The convection tubes are parallel to the water cooling wall pipes on the lower part of the hearth, and are further communicated with the horizontal drum after being bended at an angle of a into the hearth on the middle and lower part of the hearth. The horizontal boiler is further characterized in that the bending angles a of each group of the convection tubes are different. The angle a is maximally 85 degrees and minimally 15 degrees.

Description

Technical field: [0001] The invention relates to a boiler, especially a horizontal boiler. Background technique: [0002] In the prior art, the closest technical solution to this application is the horizontal boiler in use. The water wall of a conventional horizontal boiler is composed of a row of densely distributed water wall tubes. The role of the middle and lower parts of this water wall tube is Obviously, but the role of the middle and upper parts is not good. Moreover, the temperature of the conventional horizontal boiler at the rear of the furnace and the flue pipe is too high, and the heat exchange area is insufficient, resulting in a large amount of waste of energy, which is a deficiency in the prior art. Invention content: [0003] The technical problem to be solved by the present invention is to provide a technical solution for a horizontal boiler in view of the deficiencies in the prior art. , It also greatly improves the heat exchange area and reduces the wa...
