Boiler - Efficiency

Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses; Fuel to Fluid Efficiency - indicates the

Boiler Efficiency - an overview | ScienceDirect Topics

Use of air preheaters to transfer energy from stack flue gases to combustion air. The stack flue gas heat recovery equipment (i.e., air preheaters and economizers) are typically the most cost-effective auxiliary equipment that can be added to improve the overall thermal efficiency of the boiler system.

HOW A GAS-FIRED HEATING SYSTEM WORKS

Typical indicators that the Air Pressure Switch is faulty. The boiler fans starts but the boiler does not ignite. When the fan starts during the Sequence of Boiler Operation, the boiler air pressure switch must signal the printed circuit board and then ignite. But (for example) if there is a blocked flue, the air pressure will not work

Boiler – Fundamentals and Best Practices

When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.
