Technical details and manufacturing context for Water Reservoir

Definition
A water reservoir is a critical component within steam generators or water atomizers that serves as a storage vessel for water before it undergoes heating, pressurization, or atomization processes. It ensures a continuous and stable water supply to the system, maintaining operational efficiency and preventing interruptions in steam production or water mist generation.
Working Principle
The water reservoir operates by receiving and storing water from an external source (such as a water supply line or pump). It maintains water at atmospheric or slightly pressurized conditions, allowing it to be drawn into the steam generator's heating system or the atomizer's pumping mechanism as needed. The reservoir may include level sensors, overflow protection, and temperature monitoring to ensure proper water management and system safety.
Common Materials
Stainless Steel, Carbon Steel, Food-Grade Plastic
Technical Parameters
  • Capacity of the water reservoir (L) Per Request
Components / BOM
  • Inlet Valve
    Controls water entry into the reservoir
    Material: Brass or Stainless Steel
  • Outlet Port
    Connects to downstream components for water distribution
    Material: Stainless Steel
  • Level Sensor
    Monitors water level to prevent overflow or dry running
    Material: Stainless Steel with Electronic Components
Engineering Reasoning
0.1-3.0 MPa (1-30 bar) at 20-95°C
Yield strength exceedance at 4.2 MPa (42 bar) for carbon steel ASTM A516 Grade 70 (σ_y = 260 MPa) with 10 mm wall thickness and 2.0 m diameter
Design Rationale: Plastic deformation and rupture due to hoop stress (σ_h = PD/2t) exceeding material yield strength, accelerated by stress corrosion cracking in chloride environments (>50 ppm Cl⁻)
Risk Mitigation (FMEA)
Trigger Corrosion-induced wall thinning below minimum design thickness (6.0 mm for 2.0 m diameter vessel at 3.0 MPa)
Mode: Catastrophic rupture with sudden pressure loss
Strategy: Ultrasonic thickness monitoring every 500 operating hours with automated shutdown at 6.5 mm remaining thickness
Trigger Thermal cycling between 20°C and 95°C at >5°C/min rate
Mode: Fatigue crack initiation at weld seams (HAZ regions)
Strategy: Post-weld heat treatment at 620°C for 1 hour per inch thickness and thermal stress analysis using ASME BPVC Section VIII Div. 2

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion-induced leakage
Cause: Electrochemical degradation of reservoir walls due to water chemistry (pH, dissolved oxygen, chlorides) or galvanic corrosion from dissimilar metals in construction materials.
Structural fatigue cracking
Cause: Cyclic stress from fluctuating water levels, thermal expansion/contraction, or seismic activity leading to crack propagation in welds or stress concentration points.
Maintenance Indicators
  • Visible rust streaks or weeping at seams/welds indicating active corrosion
  • Unusual audible creaking or groaning during filling/emptying cycles suggesting structural stress
Engineering Tips
  • Implement cathodic protection systems and apply corrosion-resistant linings (epoxy/polyurethane) based on water chemistry analysis
  • Install automated water level controls to minimize rapid level fluctuations and add expansion joints to accommodate thermal movement
