High versus Low Pressure Steam Boilers for Breweries

The boilers we see in a lot of small breweries are low pressure boilers, say 15 PSI, which will get the job done but, in our opinion, with limitations. Here's why: Low pressure boilers lead to fluctuating steam pressure at the kettle leading to a boiler setting of roughly 7-11 PSI. Once the pressure reaches the set point and shuts off when the low point is reached, it must go

Compound steam engine - Wikipedia

A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure (HP) cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure (LP) cylinders. Multiple-expansion engines employ additional
