      May 04, 2016 · For boilers operating up to 300 psig, the accepted alkalinity range is 200 ppm to 700 ppm, with P being 60% to 80% of Total Alkalinity. Balances alkalinities are no guarantee of clean, trouble-free boilers. However, this is one of the important factors, together with others, that must be properly controlled if the boiler is to be kept clean.

      Boiler Capacity - Engineering ToolBox

      Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (h g - …
