Steam Generator vs. Steam Boiler | Powerhouse

In a firetube design, a steam boiler is a pressure vessel comprised of a large shell in which the hot gases of combustion pass through one or more boiler tubes connected to the front and rear boiler sheet. The most common firetube type is the scotch marine firetube boiler, which utilizes a large furnace tube and many smaller boiler tubes.

What is meant by once through a boiler? - Quora

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions. Mitsubishi Power delivered its first supercritical pressure once-through boiler in 1968, and followed up in 1981 with delivery of the first supercritical variable pressure once-through
