WNS natural gas fire tube steam boiler is a kind of automatic, safe and efficient heating equipment. This gas fired steam boiler is quickly installed in the bedroom with three-return fire tube boiler. It has compact structure, small size, strong load adaptability and low requirements on water quality.
This boiler adopts the boiler biliary wet back structure, has the characteristics of high temperature resistance, good sealing, large radiant heat transfer area and high heat transfer efficiency. WNS series fire tube steam boilers manufacturing are widely used in industrial production and processing, such as textile industry, pharmaceutical industry, food and beverage industry, chemical industry, clothing industry, paper industry, wood industry, etc., and can also be used for central heating of enterprises, hotels, hospitals, civil buildings.
Fire tube boilers and water tube boilers are the two main types of industrial boilers that users can purchase for specific applications, and it’s not always easy to choose the right type of boiler. It’s hard to argue that one type is better than the other: both fire tube and water tube boilers have their unique advantages and disadvantages, and a thorough understanding of the differences between the two types of boilers can help make the right purchasing decision.
Advantages And Disadvantages Of Fire Tube Boiler
- The fire tube boiler adopts wet-back boiler shell structure, large water volume and drum space, steam output and stable pressure, can be applied to users applicable process of various load sudden change.
- High adaptability to water quality, low requirements, no need for chemical treatment.
- The processing technology of fire tube steam boiler adopts advanced NUMERICAL control technology to reduce assembly stress and prolong the service life of the boiler.
- Disadvantages are slightly large volume, high manufacturing costs, working pressure generally cannot be higher than 2.5Mpa.
In the boiler body of a fire tube steam boiler, there is a large diameter pot with a fire tube and a large number of thin tubes inside. The flue gas from the combustion of the fuel passes through a fire tube or pipe and is heated to a mixture of water, steam, or soda outside the fire tube or pipe. Fire tube boiler is also called boiler shell boiler. Due to the limitation of its structural conditions, it is generally used for users with small capacity. In the range of 1-20 tons of industrial boilers, more than 90% of users choose horizontal fire-tube boilers.
