  • Control Engineering | Optimizing Strategy for Boiler Drum

    Jun 18, 2012 · The boiler drum separates steam from water and contains inventory to accommodate operational changes. Water enters the riser tube, is heated, and undergoes a transition from a single-phase liquid to a mixture of saturated liquid and steam. As heat input increases, the proportion of steam vapor in the riser tube increases. Learn More

  • Biomass Boiler - an overview | ScienceDirect Topics

    Somchart Chantasiriwan, in Computer Aided Chemical Engineering, 2020. Abstract. Biomass boiler uses thermal energy from the combustion of biomass fuel and air to produce superheated steam from feed water. Biomass fuel usually has a high moisture content, which leads to low boiler efficiency. The boiler efficiency can be increased by using heat recovery devices to decrease the temperature of Learn More

  • The Effects of Corrosion in a Boiler | Chardon Labs

    The latter compound reacts with iron in the boiler, dissolving it and producing sodium ferrate. This product then undergoes hydrolysis again, converting back to sodium hydroxide, continuing the process. Joints and bends are especially susceptible to this type of damage from sodium in the water.Learn More

  • The Importance of Boiler Water and Steam Chemistry

    The Importance of Boiler Water and Steam Chemistry. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.Learn More

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Hydrogen embrittlement of mild steel boiler tubing occurs in high-pressure boilers when atomic hydrogen forms at the boiler tube surface as a result of corrosion. Hydrogen permeates the tube metal, where it can react with iron carbides to form methane gas, or with other hydrogen atoms to form hydrogen gas.Learn More
