Boiler Blow-down Improvement Team Air Products: Brain Parris, Todd Fitzgerald, Matt Van Horn Final Concept Hold-Up Volume: 396 gallons Height: 96 inches Diameter: 54 inches Outlet Temperature: 95 F Mission Statement: To improve the steam boiler blow-down system in order to reduce the cost to operate and maintain the system in compliance with state regulations. Current Process: Water discharged from the bottom of the boiler at 365 F and 160 psig and continues to a flash tank water separates into vapor and liquid Piping Diagram Flash Tank Boiler Initial Investigation: Isolate and prioritize the different problem areas in the blow-down system. Wants • Constraints • Outlet water temperature: < 150 F • Outlet pipe area twice inlet pipe area • Water discharged to sump: < 95 F Proof of Concept Validation of analytical model using experiment Boiler Blow-Down Experiment: Acquire the flow rate of water during a blow-down Determine the amount of cooling water required to reduce the water to 95 F Work In Progress: A process and instrumentation diagram of the final concept Design Hazard Review: The HAZOP method was used to determine and eliminate any potential problems with the final design. Flow Rate: 126 gal/min Cooling Method Selection: Using thermodynamics we were able to predict which cooling method was the most efficient.
