Energy-Saving Measures and Audit Analysis for Industrial Boilers

This article provides reference material on energy-saving measures for industrial boilers. A survey should examine steam generation, distribution and end use to identify losses across the entire system.

Areas to review

• Boiler operating conditions and combustion efficiency.
• Insulation, leaks and steam distribution pipework.
• Opportunities for condensate recovery and appropriate heat recovery.
• Blowdown practices, water quality and maintenance.

The whole-system approach is explained in the US Department of Energy's steam system guidance.

Records to prepare

The survey team should compile fuel consumption, steam output, operating hours, process parameters and steam distribution diagrams. Each proposal should identify current conditions, the calculation basis, estimated cost and arrangements for monitoring after implementation.

Do not assume that a saving percentage achieved in another system will apply automatically. Equipment adjustments must follow manufacturer guidance and be carried out by competent personnel.
