Embodiment Construction

[0009] from figure 1 , Figure 2 and Figure 3, it can be seen that it is composed of furnace base 1, furnace grate 2, coal filling port 3, single drum 4, outer water-cooled elbow 7, inner water-cooled elbow 12, cupola 13, pyrotechnic pipe 14, etc. The single-drum vertical coal-fired boiler is characterized in that: the lower end of the single drum 4 extends to the lower part of the grate 2 and is equipped with a sewage pipe 21, and its end is a detachable flange 20 connected by bolts. The outer circumference of the blue plate 20 is installed with a snap-in type half-divided protective cover 15, so that the lowest part of the single drum 4 is in a non-heated area and the effect of sewage and scale removal is good, and the outer water-cooled curved pipes 7 evenly distributed on the outer circumference of the single drum 4 Two overlapping main fins 23 and two opposite secondary fins 22 are welded on the two of them. With the main fins 23 and secondary fins 22 as the skeleton, refr...

Abstract

A coalfired boiler characterized by that a single barrel drum body is used to store water directly, the lower end of the single barrel drum extends to below the grate, the water cold bending tube with fins on the cirumferential of the single barrel drum are laid with fireresisting concrete to form membrane wall, and the space between the exterior wall of the single barrel drum and the membrane wall forms sufficient furnace tank space, ring webs are arranged at the horizontal position between the center of the single barrel drum exterior wall and the membrane wall, forming a convolution air flue on the upper portion of the furnace tank space and a combusting chamber on the lower portion.

Description

technical field [0001] The invention is a coal-fired boiler with a new structure. Background technique [0002] Existing vertical coal-fired boilers all have an inner container and an outer shell. For details, see Practical Boiler Handbook P66 Chapter 3 "Structure of Industrial Boilers and Special Boilers" (Edited by Lin Zonghu and Xu Tongmo, Beijing Chemical Industry Press, June 1999, first edition ), the production process is complicated, the steel ratio is large, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to design a single-drum vertical coal-fired boiler without a liner. Compared with vertical boilers with the same evaporation capacity, the manufacturing process is simplified, the steel ratio is small, and the cost is low. [0004] The object of the present invention is achieved in this way: a single-drum vertical coal-fired boiler is characterized in that: the pot water is directly stored in the single-drum, and t...
