Sludge is the accumulation of solids that precipitate in the bulk boiler water or enter the boiler as suspended solids. Sludge deposits can be hard, dense, and tenacious. When exposed to high heat levels (e.g., when a boiler is drained hot), sludge deposits are often baked in place. Sludge deposits hardened in this way can be as troublesome as ...
It is a multi-parameter handheld meter that measures relevant parameters of the water quality by using its sensors. These include pH, redox, total hardness, acid capacity and dissolved oxygen. The overall unit is particularly easy to handle, to display and record the data.
BOILER TREAT COMBI is dosed at 0.4 l/m3 boiler water. Allow the boiler water to be conditioned for 24 hours and then carry out a P-alkalinity test. Adjust product dosage as necessary to obtain a P-alkalinity of 100 – 150 ppm. At the same time determine the chloride content. If the chlorides are too high, give the boiler a top and bottom blowdown.
Water quality monitoring is a vital step toward saving energy costs at any facility that utilizes boilers. Recent research has shown that better control of parameters such as water hardness, carbonate hardness and conductivity through online water quality monitoring can save facilities thousands of dollars annually in energy and down-time costs.

Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam plant.
Water Hardness. Hardness is a natural characteristic of much of Ireland's drinking water supply. Hard water contains high levels of natural minerals absorbed from rock and soil.
