Detailed Introduction to Common Industrial Boiler Structures

Industrial boilers are essential equipment in many industries, providing the necessary heat and energy to power various processes and operations. From manufacturing plants to power generation facilities, industrial boilers play a crucial role in ensuring efficient and reliable operations.Here are two common industrial boiler structures for your understanding.

Vertical Bent Water Tube Boiler

Vertical-bent water tube large industrial boiler consists of main components such as pot shell, furnace bladder, and water-bending pipe.The pot shell is a cylindrical shell with a convex head welded on the top. The lower part is connected to the furnace core through a U-shaped foot ring. The furnace is a small cylindrical shell with a convex furnace top welded to the top. The water-bending pipe is divided into two groups, which are arranged circumferentially inside the furnace and outside the pot shell. The upper part of the bent water pipe inside the furnace is connected to the top of the furnace and the lower part is connected to the furnace. The upper and lower ends of the bent water pipe outside the pot shell are connected to the pot shell and are surrounded by an annular flue. The grate is at the lower part of the furnace. After the high-temperature flue gas transfers heat to the furnace wall and the internal curved water pipe, it enters the annular flue outside the pot shell through the throat pipe, splits into two paths, each passing through a semicircular path, and flushes the external curved water pipe laterally. Together, they flow into the chimney.
This kind of new industrial boiler has a simple and compact structure and is easy to manufacture; it has many heating surfaces and good heat transfer; and its water circulation is reliable. The entire boiler has better elasticity and less thermal stress. However, the arrangement of the bent water pipe in the furnace reduces the volume of the volume of the combustion chamber. Increased water cooling worsens combustion conditions, so this type of boiler can only burn high-quality fuel. The horizontal section of the bent water pipe in the furnace is prone to sedimentation and scaling. When the water quality is poor, it may cause blockage and damage to the bent water pipe.

Vertical Straight Water Tube Boiler

vertical straight water tube furnace consists of main components such as pot shell, furnace bladder, upper and lower tube plates, straight water pipes, etc. The pot shell is divided into upper and lower parts, connected by a straight water pipe in the middle. There is a convex head on the top of the upper pot shell, and the lower part of the lower pot shell is connected to the furnace core with a U-shaped foot ring. The furnace is a short cylindrical shell with a convex furnace top. The opposite ends of the upper and lower pot shells are two flat tube plates, and straight water pipes are connected to the flat tube plates. In the center of the straight water pipe is a downpipe with a large diameter. The downpipe and the surrounding straight water pipes form a circulation loop. The flue gas enters the straight water pipe area from the furnace duct through the pipe. The straight water pipe is equipped with a folding smoke wall, and the smoke can only wash the straight water pipe laterally around the middle down pipe in the circumferential direction and finally be discharged through the chimney. This kind of industrial boiler has safe and reliable water circulation, high thermal efficiency, and easy cleaning, but it is easy to accumulate dust in the straight water pipe area.
