The audit which is customised for each individual client typically investigates areas from the following criteria.

• Catalogue key equipment
• Design of distribution system and condensate return system (steam traps, drop out points, pipe sizing etc)
• Steam trap survey
• This will show leaking or blocked traps. Losses shall be shown in kilograms per hour along with cost.
• Establish Flue Loss
• Consider economisers
• Establish Blowdown Loss
• Consider automated blow down
• Establish TDS Loss
• Consider automated TDS control
• Establish Hotwell/Feed Water Temperature
• Consideration given to raising hot well temperature via steam injection and or TDS heat recovery. Other methods are also considered dependent upon the client’s installation.
• Establish radiated heat loss (boiler ends, pipe work, valves)
• Consider lagging options
• Establish burner efficiency
• Consider Replacing mechanical or linked burner controls with modern independent motor-driven fuel air-mixture controls
• Consider fixed speed fans and motors with variable speed units
• Consider reducing burner size on a boiler that consistently runs below optimum load
• Consider sequencing multiple boilers using a boiler management system controlled by a plant management programme
• Establish Production Steam Load Requirements
• Consider a load balancing system which will determine when an additional boiler should be brought online as well as which units will be most efficient at given total load.
• Establish Current Operating Parameters
• Consider Operating “No Cost” Operating Improvements
• Health and safety recommendations
• Consideration given to PM5, PM60 and Safed regulations

Report Deliverables

A report will be issued to the client and dependent upon the level carried out to - will deliver the following information.

• Inventory of equipment
• Current boiler efficiency
• Recommendation of areas of improvements
• Cost of improvement
• Return of investment (where applicable)
• Efficiency percentage improvement
• Overall efficiency after recommendations has been carried out.
