Steam boilers are among the indispensable components of industrial facilities. Depending on the type of fuel, steam boiler manufacturing is carried out in various types and sizes. A total of 6 different steam boilers with different features are produced. You can find detailed information about the manufacturing process carried out by our expert team in the relevant categories and learn more about industrial boiler models, their features, and prices.
Steam Boiler
The working principle of a steam boiler is simple. In this system, liquid is pumped into the boiler, and fuel is burned in the combustion chamber. The heat generated by the burning fuel boils the liquid inside. Once the water exceeds a certain temperature, it boils and turns into steam. Harmful gases produced by combustion are filtered and discharged.
Various steam boiler designs have been developed to meet different industrial processes and needs. Each design has its own advantages and limitations. Below are the six most commonly used types of industrial steam boilers and their characteristics:
The Scotch type steam boiler, also known as an internally fired boiler, is commonly used in ships and industrial facilities with medium steam demands. Typically cylindrical in shape, these boilers contain water around the central combustion chamber and transfer heat through smoke tubes. They are known for their compact design, ease of operation, and maintenance. However, they are not suitable for very high-pressure or high-capacity applications without additional design modifications.
These boilers are designed for the efficient combustion of solid fuels like coal, biomass, or waste. A rotary grate system at the bottom feeds the fuel, and ash is automatically removed, enabling continuous combustion. They support various fuel qualities but have moving parts, increasing maintenance and initial investment costs.
Burns solid fuel in a bed fluidized by high-speed air. Known for being environmentally friendly, the reduced combustion temperature lowers NOx emissions. Adding limestone also reduces sulfur. While allowing various fuels and offering high efficiency and low emissions, their complex design requires skilled operation and a higher initial cost.
The stoker boiler feeds solid fuel into the combustion chamber via a mechanical or semi-automatic stoker system. This ensures a steady, controlled combustion process and improved operational efficiency. It supports various solid fuels and allows automation. However, its combustion efficiency is slightly lower than rotary grate or fluidized bed types, and regular maintenance is necessary due to mechanical components.
Named after its D-shaped exterior, it belongs to the water tube boiler category. Commonly used for high-pressure, high-capacity applications. The D-shaped furnace is surrounded by tube bundles that circulate water and steam, allowing rapid heating and high-pressure steam production. Efficient and responsive, but complex and costly, requiring skilled personnel for operation.
Operates by pushing fuel into the combustion chamber via hydraulic or mechanical pistons. The process optimizes airflow and fuel feed speed for efficient combustion. It supports various solid fuel types but requires higher maintenance due to moving parts. However, it is favored for its combustion efficiency and ease of ash removal.
Steam boiler hourly capacities range from 1,000 kg to 100 tons. Detailed information is in the table below:
Boiler Type | Capacity Tons/Hour |
Scotch | 1 – 40 |
Stoker | 1 – 10 |
D Type | 4 – 40 |
Fluidized Bed | 6 – 100 |
Rotary Grate | 4 – 40 |
