Steam System Study

We offer the major opportunities available to improve the energy efficiency and productivity of industrial steam systems.

This field covers five main areas of investigation:

  • Profiling a steam system
  • Identifying steam properties
  • Improving boiler operations
  • Improving resource utilization
  • Investigating energy losses in steam distribution system.

After carrying out field work, calculations and thorough analysis, we submit a quantitative report with recommendations for the improvement of steam system.

Steam System Profiling Includes:

  • Determining the total cost of fuel supplied to the boilers ($/year, $/month, and $/season).
  • Calculating the unit cost of fuel based on energy ($/106 Btu).
  • Comparing the unit cost of fuel to other available fuel supplies.
  • Determining the unit cost of electricity supplied to the facility ($/106 Btu).
  • Comparing the unit cost of fuel to the cost of electricity supplied to the facility.
  • Determining the typical steam production for the facility (lbm/h and lbm/d).
  • Determining the production cost of steam for the facility ($/103 lbm).
  • Determining the amount of steam required to produce a product (lbm steam/lbm product).

Identifying Steam System Properties Includes:

  • Determining the properties of the steam generated in the boilers (temperature, pressure, saturated, superheated, enthalpy, and the remaining thermodynamic properties).
  • Determining the properties of boiler feed water (temperature, pressure and enthalpy).
  • Determining the properties of boiler blow down (pressure, enthalpy).
  • Determining the properties of condensate return (temperature).
  • Determining the properties of makeup water (temperature).

Boiler Efficiency and Improving resource utilization Includes:

  • Determining boiler efficiency (%).
  • Investigating boiler shell for hot spots.
  • Determining boiler blow down rate (% of feed water flow, lbm/h).
  • Investigating feed water quality improvement opportunities.
  • Investigating blow down heat recovery opportunities.
  • Monitoring flue gas oxygen content (%).
  • Monitoring flue gas exhaust temperature with respect to boiler load, ambient temperature, and flue gas oxygen content (°F).
  • Monitoring flue gas combustibles (ppm).
  • Evaluating unburned carbon loss (%).
