Which type of industrial boiler is cost-effective

2021 / Jun / Thu
Our country is a country with relatively developed industrialization, and industrial boilers can be seen in many large companies and small companies. In particular, power plants, as well as various fertilizer plants, all use industrial boilers. According to the characteristics of the furnace type, it can be roughly divided into six categories. The characteristics of each different industrial boiler are different. So, what are the characteristics of industrial boilers? What types of boilers are there? Let's take everyone to understand:Generally speaking, there are many types of industrial boilers. There are mainly six types of industrial boilers, including vertical boilers, horizontal boilers, double-drum vertical type D, and double-drum vertical type O Type, double drum vertical installation type M, single drum vertical measurement type A. You will find that the vertical boiler has obvious characteristics, compact structure, relatively large area, and convenient operation and maintenance. This type of boiler is suitable for low-pressure small industrial boilers, and the capacity is generally less than or equal to 1th.

In addition, the horizontal pot shell mechanism is relatively compact, and it is assembled and shipped out of the factory. It is also convenient to install and move. It has a large water capacity and can generally adapt to load changes. It is convenient to operate and maintain, and has higher thermal efficiency than vertical pot shells. However, it also has the disadvantage of poor thermal expansion compensation ability. It is not sufficient for fuel and is widely used in many low-pressure small industrial boilers. The double-drum vertical type D type has relatively large water capacity, adapts to load changes, has good heat transfer effect, high thermal efficiency, strong generalization, and high degree of serialization.

"Hot summer and warm winter area" refers to the middle and lower reaches of the Yangtze River and its surrounding areas. The provinces involved include Shanghai, Jiangsu, Chongqing, Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Sichuan, Henan, Guizhou, Fujian, etc. At the end of 2012, the area with hot summer and cold winter had an existing building area of ​​3.4 billion square meters and a population of 100 million. If extensive heating in the heating area is adopted, the annual energy consumption will be as high as 26 million tons of standard coal.

The horizontal fire tube hot water boiler adopts the corrugated furnace design, which increases the heat transfer area and meets the need for free expansion after the record is exposed to high temperature radiation; and the furnace body has a large water capacity, and the heating is stable. Scaling is produced, and the heat exchange effect is better.
