At present, shell boilers are used very frequently in various industries and markets, and they are deeply loved by users. So which boiler models are included in the shell boiler? What are the characteristics? Let Zhengzhou Fangkuai Boiler Factory answer for you.
The basic structure of the shell boiler is a double-jacket structure. The outer cylinder is called the boiler shell, and the inner cylinder is called the furnace (fire cylinder). The annular space between the inner and outer cylinders is filled with water, and the inner cylinder is the combustion chamber. When the water vapor medium is under pressure, the shell is under internal pressure, and the furnace bladder is under external pressure. Shell boilers are divided into two types: vertical and horizontal. At present, the commonly used oil and gas boilers are WNS type horizontal internal combustion shell boilers. Shell boiler has the following characteristics:
1. Both the "pot" that holds water and the "furnace" that burns the fire are contained in a shell—the pot shell;
2. The metal furnace (furnace) has a small volume, is surrounded by water, has a large degree of water cooling, and has poor combustion conditions. It is necessary to burn high-quality fuel;
3. The heating surface is small, and the evaporation or heating power is small. Water pipes or pyrotechnic tubes are often installed to increase the heating surface and boiler capacity;
4. The pot shell has a large diameter, many openings, and irregular shapes. The internal heated part and the unheated part are connected together, and the temperature and thermal expansion degree are different, so the safety of the shell is poor; 5. The boiler structure system is relatively simple, which is convenient for transportation, installation, operation management, inspection and maintenance.
The above are the characteristics of shell boilers summarized by Zhengzhou Fangkuai Boiler Factory.
