high temperature coal fired steam boiler Agent

PentoMag® | Additive for Coal Boilers - Pentol

Anti slagging additive for coal fired boilers. PentoMag 2550 increases the fusion temperature of metals in fly ash. Thus preventing that ash can stick to the boiler walls. It changes the amorphous structure by forming friable crystals with low density. Their removal will usually lower the maintenance.

Application of high steam parameter for High sulfur coal

designs. The high temperature corrosion of superheater and reheater tubes in coal-fired boilers is normally caused or accelerated by molten salts consisting of sodium-potassium-iron tri-sulfates (Na,K) 3Fe(SO 4) 3 in deposit ash. Figure 3 shows a schematic illustration of the progress of such high temperature corrosion during operation. - 5 -

1.1 Bituminous And Subbituminous Coal Combustion

The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.

How to regulate the temperature of coal fired steam boiler

Apr 12, 2018 · But the temperature should not be too high to prevent vaporization and big temperature difference; generally the temperature should be among 20 ℃-70 ℃. When the feeding water is over, increase the pressure to 0.4MPa gradually, then conduct a rigorous check, and tighten the flange manhole cover and hand-hole cover nut if necessary.
