Controlling TDS in the Boiler Water | Spirax Sarco
By installing an automatic TDS control system the average boiler water TDS can be maintained at a level almost equal to the maximum allowable TDS as shown in Figure 3.12.9; Evaluating savings by reducing blowdown rate. If a boiler is to supply a given amount of steam, the water blown down must be in addition to this amount.

Steam Boiler Water Dissolved Solids, TDS Control
As steam is evaporated the concentration of total dissolved solids (TDS) increases in the boiler water. If the TDS concentration is allowed to get too high then carryover of boiler water will occur. This carryover can cause serious damage to the steam and condensate systems through corrosion and deposition on heat transfer surfaces.

Boiler Water Conductivity Measurement Fundamentals
As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. is a high Total Dissolved Solids (TDS) level. Careful control of boiler water’s TDS level, together with attention to these other factors should ensure that the risk of foaming and

Effects of High TDS Levels in Feed Water to Boiler
Carryover of these solids with the steam reduces the quality of steam and also damages the control valves, heat exchangers and steam traps placed in the steam line. For Example If TDS concentration in feed water is maintained at 1000 ppm, steam dryness will reduce to 85% so this will lead to increase blowdown frequency to maintain the TDS

Blowdown in Boiler | Boiler Blowdown Calculation Formula
Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.

TDS Blowdown Controls | US | Spirax Sarco
During formation in the boiler, steam leaves behind impurities (TDS - total dissolved solids). If left these concentrate and cause damage to the boiler. High TDS results in plant and production problems. Low TDS results in increased fuel and chemical treatment costs.

Automatic Boiler Blow Down System – Volfram Systems
The TDS level inside the boiler varies with: Feed water TDS: If the feed water TDS increases then the Boiler TDS increases quickly for the same steam load. Steam Load: If the steam load increases then the Boiler TDS increases quickly for the same Feed Water TDS. To maintain the level of Total Dissolve Solids (TDS) inside the boiler within the permissible limit, boiler water is drained
