Burner Replacement Services

Many older boilers in service today don’t perform at their peak. Even if they did, their antiquated technology limits their potential. Today’s high-efficiency boilers feature sophisticated improvements compared to their aging predecessors, including computer-aided design tools, metallurgical enhancements, and more efficient and reliable boiler structure.

But the most striking advancement of all can be seen in today’s burners. Many times, we can retrofit older boilers with new burners to drastically improve efficiency and reduce emissions. With this upgrade, you have the potential to save thousands in unnecessary fuel expenses and exceed regulatory requirements for heating emissions in your industry.

You may be eligible for a burner replacement if the pressure vessel and other vital components of your existing boiler are in good shape. A knowledgeable Murphy & Miller technician can visit your site, assess your heating system, and recommend the best course of action for improving performance, which may include replacing the burner.

Problems with Aging Burners

Old boilers adjust fuel and air flowing to the burner with mechanical linkages. These often don’t function well if the demand for steam or hot water is below 35 percent load. The required purges and reheating cycles can be incredibly inefficient.

What’s more, mechanical linkages respond slowly, meaning the fuel-air mixture is often inaccurate. To improve precision, correct weakened joints, and tighten loose screws, old burners must be checked and rebalanced regularly.

Mechanical linkages are also associated with hysteresis, or linkage slop. This is when the burner operates in a rich or lean condition that leads to inefficient fuel consumption. As the system ages and experiences more wear and tear, linkage slop increases, even when the control is calibrated as accurately as possible.

Overcoming Boiler Inefficiencies with Burner Replacement

The key to eliminating problems with your aging burner is to replace it with one that doesn’t use mechanical linkages. Many new burners use controls with parallel positioning systems, which move into a preset position according to the system’s fuel and air flow needs. With such precision and repeatability, new burners achieve the ideal fuel flow for the required heating load.

Another beneficial aspect of new burners and controls is their ability to optimize combustion in response to changing atmospheric conditions or variations in fuel pressure. This is possible thanks to exhaust oxygen feedback, which works similarly to oxygen sensors in vehicle exhaust systems. This results in stable firing at a lower fuel consumption level, allowing for greater turndown ratios and reduced boiler cycling.
