If the system is operated only with natural/assisted circulation, the application range is limited to a max drum pressure of approx. 190 bar. If a circulating pump is used (forced circulation), this range can be extended somewhat fixing the endpoint of evaporation in the drum also sets the size of the heating surface in the evaporator & superheater.

Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork ...
