Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] In the embodiment of the present invention, such as Figure 1~3 As shown, a concentric truncated circular combustion chamber boiler is provided, which includes an outer cylinder body 1 , and a furnace gall 5 , a combustion chamber 3 and a smoke pipe 2 are arranged inside the outer cylinder body 1 . The front and rear ends of the outer cylinder body 1 are set as tube sheets, preferably flat tube sheets. In order to reduce the diameter of the outer cylinder 1 and improve the utilization rate of the inner space of the outer cylinder 1, when designing and manufacturing, the diameter of the combustion chamber 3 and the diameter of the outer cylinder 1 are set to be not much different, and then the combustion chamber 3 is arranged concentrically with the outer cylinder 1. In the present invention, the difference between the diameters of...

Abstract

The invention discloses a boiler with a concentric-truncated-circle reburning chamber. The boiler comprises an outer cylinder body, wherein the front end and the rear end of the outer cylinder body are arranged as flat tube plates; the outer cylinder body is internally provided with a furnace container, a reburning chamber and smoke tubes; the reburning chamber is a truncated circular cylinder body with a truncated upper portion and is arranged concentric with the outer cylinder body; one end of the reburning chamber communicates with the furnace container, and the other end of the reburning chamber is fixedly connected with the rear tube plate of the outer cylinder body; the furnace container is fixedly connected to the lower part of the reburning chamber, and the inlet of the furnace container is connected with a burner connecting pipe arranged on the front tube plate of the outer cylinder body; and the smoke tubes are distributed around the furnace container, one end of each smoke tube communicates with the reburning chamber, and the other end of the corresponding smoke tube communicates with the front tube plate of the outer cylinder body. According to the boiler with the concentric-truncated-circle reburning chamber, by adopting the boiler with the structure, the problems that the diameter of the outer cylinder body is larger, the water volume in the outer cylinder is large and the load response time is long can be effectively solved.

Description

technical field [0001] The invention relates to a boiler, in particular to a concentric truncated circular combustion chamber boiler. Background technique [0002] According to the national boiler standard, a certain steam space must be left between the combustion chamber and the outer cylinder of the manufactured boiler. In order to meet this requirement, manufacturers often eccentrically arrange the backfire chamber and the outer cylinder. This design will not only increase the diameter of the outer cylinder, increase manufacturing costs and floor space, but also increase the gap between the outer cylinder and the backfire chamber. There will be a lot of idle space, which will lead to an increase in water volume and a long load response time, which is not conducive to industrial production. Contents of the invention [0003] In view of the above-mentioned prior art, the present invention aims to solve the technical problems of large diameter of the outer cylinder, large...
