what is the hardness standard of boiler furnace water

Boiler Water Quality

Boiler Water Quality Boiler Chemicals are used to ensure proper Boiler Water Quality in boilers. The below table is the Total Dissolved Solids or TDS Alkalinity and Hardness versus Boiler Pressure. First knowing the water source is important whether it is from ponds rivers ground wells or city water.

furnace water hardness how to calculate boiler water slag

Water quality instructions for central heating systems. Water treatment when hardness levels are too high If the water hardness level is too high limescale can form in high-tempera­ ture areas of the system particularly in the central heating boiler. Lime­ scale deposits reduce efficiency and cause heat loss and mechanical faults.

Heating : what is the VDI 2035 directive ? - ThermoGroup

VDI Guideline 2035 sets pH and water hardness values in a diagram that is easy for all professionals to read. The permitted hardness is expressed in °dH. The permitted hardness is expressed in °dH. It depends on the efficiency of the boiler measured in kW and the volumes of specific installations or after-sell service of the heating system.
