BRIEF HISTORY OF WATER-TUBE BOILERS 1 –

2007-9-18 · The first successful user of water-tube boilers, however, was James Rumsey, an American inventor, celebrated for his early experiments in steam navigation, and it is he who may be truly classed as the originator of the water-tube boiler. In 1788 he patented, in England, several forms of boilers, some of which were of the water-tube type.

What is a Steam Boiler? Classification of Steam Boilers

Today’s steam generating systems owe their dependability and safety to more than 125 years of experience in the design, fabrication and operation of water tube boilers. Boiler classification can be based on many factors like usage, fuel fired, fuel firing system, type of arrangement etc. The commonly known types are pulverized coal fired boilers, fluidized bed boilers, super critical boilers
