MgCl2 is soluble under normal boiler condition but can do some extent break down inside the boiler to form Mg(OH)2 and HCL –this can set up an active corrosion with in the boiler metal.Learn More

  • Water for the Boiler | Spirax Sarco

    Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence.Learn More

  • Why you can't use high-pressure steam boilers on low

    A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.Learn More
