The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent Evaporation in a causes impurities to concentrate This interferes with heat transfers and may cause hot spots Leading to local overheating Scaling mechanism is the exceeding of the
Step 1 Pour water in a clear container and allow it to stand An iron to Iron is not generally harmful at this level so an unhealthy level of iron in the
oxide is an increasingly significant contributor to deposits because of the virtual elimination of hardness deposits in many systems and because the high heat transfer rates of many encourage deposition Chelants with high stability values such as EDTA can complex deposits
Chelating are expensive chemicals and must be investigated to determine the optimum concentration pH and treatment time at 150°F 01g of sulfide composed of mainly troilite was used as the 10 cm 3 of EDTA DTPA and HEDTA solutions were prepared at different concentrations ranging from 005 to 04 mol/L using deionized
