  • Steam Boilers – Accuracy Matters – WCP Online

    Apr 17, 2014 · Boiler feedwater (FW) for industrial boilers is a combination of pretreatment make-up and condensate return (CR), (FW = CR+MU). In boilers, not all water escapes as steam. In many applications, only part of the steam exits through the process. This unused steam returns to the boiler as condensate—referred to as condensate return.Learn More

  • Boilers - University of Alabama

    Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressureLearn More

  • Pressurised Deaerators | Spirax Sarco

    Due to the rising cost of chemical treatment, it is proposed that a pressurised deaerator be installed, operating at 0.2 bar g to raise the feedwater temperature to 105°C, reducing the solubility of oxygen to quantities typically measured in parts per billion. Steam, produced in the boiler at 10 bar g, is to be used as the heating agent.Learn More
