Basics of the water chemical mode of low-pressure steam boilers …
There is a clear tendency that the requirements for low-pressure boilers were simply copied from high-pressure boilers (with the exception of the requirements for steam quality). As a result, we get very strict requirements for the organization of the WCM of the boiler house, but in practice, for small enterprises of a non-energy profile, we observe an almost complete absence of such.

Water Tube Boilers | Spirax Sarco
However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs. To keep the same level of steam output at higher design pressures, the distance between the lower drum and the steam drum must be increased, or some means of forced circulation must be introduced.
