Fire tube steam boiler: an efficient and stable heating option

In the realm of industrial heating, Fire Tube Steam Boilers have emerged as a paramount choice due to their exceptional efficiency and reliability. At Brit Boiler, we understand the crucial role these boilers play in various industries, and we are dedicated to providing you with comprehensive insights into their advantages and optimal utilization.

What is a fire tube steam boiler?

A fire tube steam boiler, also known as a shell boiler, is a boiler that uses a fire tube (or other shaped shell) as a combustion chamber and flue to transfer heat to water to generate steam. Its basic structure is to install a small cylinder, tube or other shaped shell inside a large cylinder. The fire tube is isolated from the large cylinder and forms a jacket. The water in the jacket is heated and vaporized to form steam. This kind of boiler usually uses gas or oil as fuel. The high-temperature flue gas generated by combustion transfers heat to water through components such as fire tubes and furnaces, causing it to generate steam.

Fire tube steam boilers have high thermal efficiency, low energy consumption and stable steam production. In many industrial fields, such as textiles, chemicals, papermaking, food processing and other fields, as well as in heating systems, a large amount of steam is required, so fire tube steam boilers are widely used in these fields. In addition, the simple structure, easy operation and low maintenance cost of fire tube steam boilers also make it the first choice in many industrial fields.

How do fire tube steam boilers work?

The core part of the fire tube steam boiler includes the combustion chamber and the fire tube. When the boiler is running, fuel is burned in the combustion chamber, producing a large amount of heat energy. This thermal energy will heat the fire tube, causing the water in the fire tube to heat and vaporize, forming steam. Steam can be used to drive steam turbines or heat heating pipes to achieve energy conversion and utilization.

What are the types of fire tube boilers?

Types of fire tube steam boilers

1. Horizontal Fire Tube Steam Boiler: Horizontal fire tube steam boiler is a common boiler type with the combustion chamber located below the fire tube. This boiler has a compact structure and small footprint, making it suitable for applications of all sizes.

2. Vertical fire tube steam boiler: The combustion chamber of the vertical fire tube steam boiler is located above the fire tube. This kind of boiler is easy to install and maintain, and is widely used in small and medium-sized heating systems.

Advantages and disadvantages of fire tube steam boiler.

Fire tube steam boilers have certain advantages in some aspects, but there are also some disadvantages.

advantage:

1. Simple structure: The fire tube steam boiler has a relatively simple structure and is easy to manufacture and maintain.

2. High thermal efficiency: Because the fire tube boiler has a large heating area and high heat conduction efficiency, it can generate a large amount of steam.

3. Stable steam pressure: The steam pressure of fire tube steam boilers is relatively stable and can meet the needs of various industrial productions.

4. Strong fuel adaptability: Fire tube steam boilers can adapt to various types of fuels, such as oil, gas, etc., so they have good energy utilization efficiency.

shortcoming:

1. Fire tube boilers are larger in size and occupy a larger area.

2. The temperature in the furnace is prone to fluctuations, affecting steam generation and pressure stability.

3. A large amount of oxygen is consumed during the combustion process. If there is not enough oxygen supply, it will adversely affect the normal operation of the boiler.

4. The repair and maintenance of boiler equipment is difficult and requires professional technical personnel for maintenance and management.

5. Due to the large amount of smoke emitted, it is easy to cause pollution to the environment.

What industries can fire tube steam boilers be used for?

Fire tube steam boilers are widely used in many fields. The following are some of the main application fields:

1. Industrial production: In many industrial production processes, steam is required as an energy source and process fluid. For example, in the textile industry, steam needs to be used to heat and shape textiles; in the chemical industry, steam needs to be used to heat chemical reactions and promote reaction speed; in the paper industry, steam needs to be used to heat and soften paper . Fire tube steam boilers can provide high-temperature and high-pressure steam to meet the needs of these industrial productions.

2. Heating system: A large amount of hot water or steam is used as a heat source in the heating system. Fire tube steam boilers can provide a large amount of stable, high-quality steam, which is converted into hot water through a heat exchanger to meet the needs of the heating system.

3. Food Processing: During food processing, food needs to be heated and sterilized. Fire tube steam boilers can provide high-temperature and high-pressure steam for heating and sterilization during food processing.

4. Brewing industry: During the brewing process, the fermentation tanks need to be heated and sterilized. Fire tube steam boilers can provide high-temperature and high-pressure steam for heating and sterilizing fermentation tanks.

5. Petrochemical Industry: In the petrochemical industry, petroleum is treated and processed using steam. Fire tube steam boilers can provide high-temperature and high-pressure steam to meet the needs of the petrochemical industry.

6. Washing and ironing industry: Washing machines and ironing machines require the use of steam to heat and soften clothing. Fire tube steam boilers can provide high-temperature and high-pressure steam to meet the needs of these industries.

7. Other fields: In addition to the above fields, fire tube steam boilers are also widely used in other fields, such as machinery manufacturing, construction, transportation, medical and health, etc.

How do I choose a fire tube steam boiler?

When choosing a fire tube steam boiler, you need to consider the following points:

• Actual needs: Determine the model and parameters of the boiler according to actual needs, such as steam volume, pressure, etc.

• Fuel type: Choose the appropriate boiler according to the type of fuel used, such as oil, gas, etc.

• Operating costs: Consider the operating costs of the boiler, including fuel consumption, maintenance costs, etc.

• Safety performance: Choose a boiler with good safety performance to ensure the safe operation of the equipment.

• Manufacturer reputation: Choose a manufacturer with good reputation and after-sales service to ensure the quality and after-sales service of the boiler.

How much does a fire tube steam boiler cost?

The price of fire tube steam boilers varies depending on factors such as model, parameters, fuel type, and manufacturer. Generally speaking, the price of fire tube steam boilers ranges from tens of thousands to hundreds of thousands of yuan. When purchasing, you need to make a choice based on actual needs and economic conditions.

Conclusion

In short, fire tube steam boilers have been widely used in various fields due to their high efficiency and stability. When selecting and using a fire tube steam boiler, you need to consider various factors such as actual demand, cost, and safety performance to ensure its long-term, stable, and safe operation and provide stable and efficient energy support for your business or life.
