  • Ultrapure water - Wikipedia

    In steam power generation silica can form deposits on heat-exchange surfaces where it reduces thermal efficiency. In high temperature boilers, silica will volatilize and carry over with steam where it can form deposits on turbine blades which lower aerodynamic efficiency. Silica deposits are very difficult to remove.Get Price

  • High Pressure Boilers - IQS Directory

    High pressure boilers heat water to create steam at over 15 psi and have water pressure over 160 psig. Combustion Efficiency: Combustion efficiency is how well the fuel is being used in combustion, which is different from stack loss, the heat carried away by flue gases and moisture.Get Price

  • Water for the Boiler - Spirax Sarco | First for Steam

    This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam. This means that even a small percentage blowdown can represent a high mass to be blown down. Water-tube boilers tend to operate at higher pressures, usually up to 150 bar g.Get Price

  • Briquetting machines - We are #1 in Briquette Machine

    Although rice husks are perfect for briquetting, they also contain a high silica content, resulting in a high ash content. Briquettes from rice husk are most often used in boilers or furnaces with very high burning temperature to avoid a low silica melting point and sintering (crystallization) of ash.Get Price
