Steam Generator vs. Steam Boiler Powerhouse

The larger capacities of a steam and hot water boiler are powerful enough to support large-scale, high demand critical operations that see swings in steam demand. The water stored in the steam boilers allows for a much better response to changing steam demand from the plant than the single through design of a steam generator.
