Apr 16, 2013 · Most gas-fired boilers need little periodic cleaning on the combustion side, but the water-steam side needs close watching. Tube inspection will note scale buildup from feedwater. Just an eighth-inch of scale can drop heat exchange efficiency by several percent. Inspection may reveal the need for changes in feedwater treatment.
Predicting off-design performance In order to evaluate the temperature profiles in the fired mode or other off-design cases, a HRSG simulation analysis should be done. This analysis estimates the (UA) value of each surface and corrects it for the off-design or fired conditions for the effects of gas flow, gas analysis and temperature.[U

specifically firetube type boilers. Remember, the initial cost of a boiler is the lowest portion of your boiler investment. Fuel costs and maintenance costs represent the largest portion of your boiler equipment investment. Not all boilers are created equal. Some basic design differences can reveal variations in expected efficiency performance
In the U.S. boilers over 300 000 Btu/hr (88kW) are subject to standards under the National Energy Policy Act, which states that large gas-fired boilers must have a steady- state thermal efficiency of at least 80%, and large oil-fired boilers must have a steady-state thermal efficiency of at least 83%.
Apr 16, 2013 · Natural gas-fired boilers are clean and have high inherent efficiency because of the ideal nature of the fuel. Yet a systematic approach to saving energy at the boiler plant and through the system can yield significant additional energy savings, not to mention improved reliability and lowered greenhouse gas emissions.
fuel-to-steam efficiency. The table relates stack readings to boiler performance. On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Suggested Actions
