What is the Benefit of a "Once-Through" Boiler Design

With a traditional boiler, you would either need to wait an hour for the boiler to get up to speed and meet the demand or keep it running idle all the time, which wastes energy and money. However, a "once-through" modular boiler can be turned on as soon there's a spike in need.

The once through boiler works on the principle of critical point of water. In Rankine cycle, as the pressure increases the saturation temperature equivalent to that pressure also increases. At the pressure of 22.06 MPa and 373.946oC, the water gets directly converted in to steam. Thus, as we go on increasing the pressure, the amount of latent
