ADVANTAGES OF «BENT-IRON» OVER TRADITIONAL
STEAM BOILERS
Practical indicators always differ from theoretical ones. Typically, the description of classic boilers indicates theoretical values of efficiency, fuel consumption, etc., under ideal operating conditions.
However, it’s crucial to understand and consider operational efficiency – this is the actual indicator that reflects the boiler’s effectiveness under real operating conditions, taking into account various operating modes, heat costs for startup, maintaining standby mode, purging, and more.

Bent-Iron steam generators feature a heat exchanger in the form of a coil, which has a very low water volume compared to traditional drum boilers.
The absence of large pressurized vessels eliminates the possibility of explosion and makes Bent-Iron steam generators absolutely safe.
The once-through steam boiler provides the highest steam quality indicators compared to other types of boilers. The steam dryness is 99.5% at any load and operating mode.
This significantly reduces the content of water and impurities in the steam, ensuring greater energy capacity of the heat transfer medium.
This is particularly important for any food production technologies.
The design of the once-through steam boiler ensures an extremely quick reaction to any fluctuations in steam consumption.
Bent-Iron steam generators rapidly increase and decrease productivity, maintaining stable pressure and high steam quality under any operating conditions.
In steam boilers, blowdowns are necessary to prevent sediment deposition on heat exchanger surfaces.
Bent-Iron once-through steam boilers require an extremely low amount of blowdowns and have the capability for highly efficient cleaning of the heat exchange surface. As a result, this saves fuel and chemical reagents used for boiler water treatment.
Bent-iron steam generators have state-of-the-art automation systems based on the Siemens controller. All systems can be controlled via the touch panel on the control cabinet or remotely via the dispatching and remote monitoring function.
The operation of Bent-iron steam boilers does not require the constant presence of an operator.
Thanks to the technological solutions in the design of Bent-Iron steam generators, maintenance costs are minimal. All components have been developed over many years and continue to be improved daily to meet modern technological trends.
Due to their small dimensions, Bent-Iron once-through steam boilers occupy less space compared to traditional drum boilers and require smaller service areas. This significantly reduces the costs associated with boiler room construction and allows for equipment placement closer to the consumer.
Starting a traditional drum boiler typically requires 1 to 2 hours from a cold state. Due to the small number of inert components and the low volume of the heat exchanger, Bent-Iron steam generators reach operating mode in 20-40 minutes. This allows for savings on fuel costs, electricity, and operator labor expenses.
The content of pollutants in the flue gases complies with the requirements of current EU legislation.

IDEAL SOLUTION FOR
Dairy and cheese production technologies are characterized by highly unstable steam demand, which can fluctuate from 30% to 100% of their capacity in just 5 minutes. This variability requires steam generation systems to have a high level of adaptability and quick response to fluctuations in production needs to ensure uninterrupted technological processes and maintain product quality.
Once-through steam boilers are best suited for this task due to their low water content in the heat exchanger and the absence of large inertial components.
Steam is used in brewing processes by numerous breweries worldwide. High-quality steam ensures uniform heating and stable brewing conditions. Market leaders specifically choose once-through boilers because they provide ideal parameters for process steam and save costs through high energy efficiency.
