Quickly Quantifying Potential Savings When Evaluating a Miura Boiler Solution

One of the most common questions customers ask early in the sales process is simple: "How much could I save by switching to Miura?" Applications Engineering has developed a standard comparison format to answer that question quickly and consistently by comparing an existing boiler system against a proposed Miura configuration.

The Boiler Utility Comparison form is available for all Miura employees and representatives to use.

When Should It Be Used?

A boiler utility comparison is best suited for customers who already know their approximate steam demand and want a preliminary estimate of fuel consumption, utility costs, efficiency improvements, and operating savings. It is often used during initial project discussions to support payback and ROI conversations.

Required Inputs

To generate a meaningful comparison, the following information should be collected:

• Maximum, average, and minimum steam demand
• Operating steam pressure
• Feedwater temperature
• Condensate return percentage
• Fuel type and fuel costs
• Operating hours and days of operation
• Existing boiler manufacturer, model, capacity, and operating characteristics
• Existing boiler efficiency (or supporting monitoring data)
• Current utility costs for fuel, water, and electricity

If the existing boiler efficiency is unknown, available combustion monitoring data can be used to estimate efficiency through the Fuel-to-Steam Efficiency Calculator. Typical inputs include flue gas temperature, combustion air temperature, and oxygen content.

Outputs

The resulting report provides:

• Estimated fuel savings
• Water savings
• Electrical savings
• Efficiency improvements
• Utility cost comparisons
• Annual operating cost projections between the existing system and the proposed Miura system

Key Assumptions

Every comparison relies on assumptions that influence the final results:

• Boiler efficiency values are either provided by the customer or estimated from available operating data.
• Steam demand values represent actual operating conditions rather than design-only loads.
• Utility rates reflect current costs and are not adjusted for future market changes.
• Selected load profiles accurately represent facility operating patterns.

Limitations

The comparison is intended as a planning and sales-support tool rather than a guarantee of future performance. Results may differ if:

• Operating hours change significantly.
• Utility costs fluctuate.
• Actual loads differ from supplied information.
• Boiler efficiency assumptions are inaccurate.
• Feedwater conditions fall outside expected operating ranges.

Feedwater temperatures above 250°F should always be reviewed by Applications Engineering prior to proceeding because of potential impacts on feedwater pumps, economizers, and associated components.
