Steam Generator vs. Steam Boiler | Powerhouse

While steam generators are quicker to start up, they are limited in size as their maximum capacity falls short of a typical watertube boiler. Steam boilers, on the other hand, are designed for long-term industrial use. The larger capacities of a steam and hot water boiler are powerful enough to support large-scale, high demand critical
