Working principle of steam generator pressure controller

An introduction to steam generation and distribution

Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.

Steam Boiler | Working Principle and Types Of Steam Boiler | …

Steam boiler is nothing but a closed vessel combustion chamber which generates steam at a desired pressure by the combustion of fuel to water. Steam is supplied to the steam boiler in differen field like steam engine, steam turbine, thermal power plant,various heating installation process,different cotton mills,sugar factories etc.

Steam generator (boiler) - Wikipedia

A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.[1] The narrow-tube construction, without any large-diameter drums or
