Steam generator

1. Different Safety Levels

Steam boilers operate at higher pressure values, which entail certain risk factors. In contrast, steam generators have a higher safety coefficient than steam boilers. Their pressure values are lower, and when critical levels are reached, intelligent controls activate—cutting off water, power, and gas—to initiate automatic protection procedures, thereby enhancing safety to some extent.

2. Different Registration and Inspection Requirements Steam boilers and steam generators have an inclusive relationship; strictly speaking, steam boilers include steam generators, but steam generators are not steam boilers. Both steam generators and steam boilers are equipment that produce steam or hot water for commercial or industrial purposes. What are the differences between them? Which is better, a steam generator or a steam boiler? Let’s explore below. I. Differences Between Steam Generators and Steam Boilers

3. Different Capacities

In practical applications, steam generators have a smaller capacity, with tonnage typically ranging between 1-2 tons (per unit), making them suitable for industries with relatively low steam production demands.

On the other hand, steam boilers have a relatively larger range of tonnage. Boilers can be categorized by evaporation capacity, making them suitable for industries requiring high steam production.

4. Different Operating Temperatures

Steam generators and steam boilers also differ in operating temperatures. Steam generators, with their smaller tonnage, operate at around 170 degrees Celsius, while steam boilers operate at temperatures above 200 degrees Celsius.

It is widely known that steam boilers operate under high pressure, which introduces certain instability factors. Therefore, steam boiler operations require registration and filing, and specialized quality supervision departments in China conduct regular annual inspections to ensure safe usage. In contrast, steam generators are considered small-scale equipment and do not require registration or acceptance inspections; they can begin operation after installation and debugging.

5. Different Energy Efficiency Rates

Traditional boilers consume relatively more energy during operation. Steam generators, during production, can utilize high-temperature flue gas as a heat source for recovery, reducing fuel consumption. Their IoT-enabled intelligent frequency conversion systems are more energy-efficient compared to the frequent start-stop cycles of traditional three-stage fire boilers. In terms of energy efficiency rates, steam generators hold a distinct advantage.
