In a Constant Pressure OTSG (Once-Through Steam Generator) boiler design, the system operates efficiently by maintaining a consistent pressure throughout the majority of its operational range. This characteristic is crucial for ensuring stable thermal conditions and optimizing steam quality, as fluctuations in pressure can result in inefficiencies and problems with steam generation.

The design is tailored to handle a specific set of operational parameters, which includes consistent pressure levels that are maintained during steady-state operation. By achieving this stable pressure, the boiler can provide accurate and reliable steam output, which is essential in various industrial processes where precise temperature and pressure control are necessary for safety and efficiency.

Maintaining the same pressure helps in achieving optimal heat transfer and ensures that the system operates within design specifications, ultimately allowing for more predictable performance and greater energy efficiency.
