The most important part of the brewery steam system design is to size the boiler properly. An oversized boiler can result in frequent cycling while an undersized boiler may never be able to meet the temperature requirements of the brewery. Both of which will adversely affect the brewing process. A steam boiler should be sized according to the connected load. The connected load includes all the vessels and tanks as well as the piping. The manufacturer of the brewing equipment should provide the Btu consumption of their equipment. Another sizing consideration is the planned expansion of the brewery. Since the market of brewing and distilling is growing, the boiler you design today may be undersized next year.
