Balanced steam availability
Many processes have rapidly changing steam consumption or production profiles. Boilers balancing the steam pressure on the grid often cannot keep up with these fluctuations. This results in either steam production running above demand for prolonged times or grids not being able to absorb steam that could have displaced fossil fuel use. To keep pressure in a safe range, excess steam is blown off, and this is typically taken for granted. However, blowing off your surplus while burning fossil fuel later on to meet demand can be easily avoided using a steam accumulator.
Stork is a renowned OEM of boilers, burners and pressure vessels. Delivering high quality is at the core of our company values. A solid and experienced team of engineers that understands your process guarantees providing the optimal solution.
Steam accumulators are large pressurized water containers. When there is a surplus of steam, it is injected into the mass of water stored under pressure in the accumulator. When there is a demand for steam, the stored steam is released to the medium/low pressure steam grid.
A Stork steam accumulator can accept superheated and saturated steam, as well as hot water as a heat source, and supply both when demand exceeds steam production.
Complete project management or as a standalone product
Key to the success of the Stork Steam Accumulator is the simplicity of the product. Depending on your requirements and location, we can either provide the steam accumulator as a separate product or as an integrated solution.
Our steam accumulators are designed to match your process conditions. Our team of specialists will help you understand the imbalances in your process and optimize the accumulator for maximum return on investment (ROI).
Rethink your steam cycle
Our experts can provide a highly optimized integrated solutions package for your process. For instance, combining the steam accumulator with an E-boiler opens up the possibility to further reduce energy costs and make even more money by producing steam from surplus renewable energy that can be used later on.
So whether you are looking for a steam accumulator as an energy buffer in your existing factory, or want to optimize your new plant right from the start by integrating a solutions package, Stork can provide the optimal solution.

The benefits of a steam accumulator
- Reduces steam venting
- Reduces CO2 emissions
- Reduces fuel consumption
- Instant access to hot water or steam
- Reduces or even eliminates the need for surplus backup steam generation
Leaflet - steam accumulators
The push to reduce carbon emissions is ever-increasing. An often overlooked source of CO2 emissions is blown off steam. Steam accumulators store excess steam for later use, reducing fuel consumption, steam blow off and CO2 emissions.
