What is a steam generator?
A steam generator is a system that heats water and converts it into steam. Its distinguishing feature is the relatively small volume of water held inside the system at any given time. Because less water needs to be heated, the system starts producing steam relatively quickly after it is activated.
The key difference from a conventional steam boiler
A conventional steam boiler stores and heats a large volume of water; it takes longer for the first steam to be produced, but it builds up a large steam reserve. In a steam generator, the water volume is smaller. This means both faster steam production and less water—and therefore less stored energy—present in the system at any given time.
When is each one suitable?
Which system is suitable depends on the size and continuity of your steam requirement, as well as your operating conditions. Steam generators are commonly preferred for applications such as ovens, where steam is needed at specific times and must be produced quickly. Stilsan sizes and manufactures the system according to your requirements.
Frequently asked questions
- What is the difference between a steam generator and a steam boiler?
- The main difference is the water volume. A steam generator operates with a small volume of water and starts producing steam quickly, whereas a conventional steam boiler stores and heats a large volume of water. The first steam arrives later, but the boiler builds up a large reserve.
- Why does a steam generator produce steam faster?
- Because it contains less water at any given time, it takes less time to convert that water into steam. The smaller water volume allows steam to become available relatively quickly after the system is activated.
- Is a steam generator or a boiler suitable for my business?
- This depends on the size and continuity of your steam requirement and your operating conditions. If you share your requirements, we can determine the suitable system and sizing for you.
