Measuring TDS with the density method. TDS = 1.1 106 (ρ - 1) (1) where. TDS = Total Dissolved Solids (ppm) ρ = relative density of the boiler water at 15.5oC. This is a manual method requiring measuring a cooled down sample with a very sensitive hydrometer.
SPM from coal power plants are mainly soot, smoke and fine dust particles and these cause asthma and respiratory illness. 2. Water Pollution. In a coal power plant, water is used for washing coal, circulating in the boiler furnace to produce steam and cooling of equipment. The dust from coal-cleaned water contaminates groundwater.
Characteristics of boiler feedwater - Lenntech
Since water impurities cause boiler problems, careful consideration must be given to the quality of the water used for generating steam. The composition of boiler feed water must be such that the impurities in it can be concentrated a reasonable number of times inside the boiler, without exceeding the tolerance limits of the particular boiler

the boiler water, creating a density dif-ference. This system can be explained and modeled by a U Tube Manometer (Figure 4). The manometer contains fluid with three different densities. On one side is saturated water with boiler water den-sity D d. On the other side are two flu-ids: water in the gage with an unknown density D g, and saturated

Sep 02, 2014 · Water boiling at 1310 PSIG is 580°F and is only 73% as dense as 100°F water. Saturated (not superheated) steam at 1310 PSIG is 5% the density of 100°F water. For example, if a drum were full of 580°F water up to the top tap 50" above a bottom tap, it would register over 13" of DP, instead of the 0" DP it would read if the densities were the same.
