Combustion Air Requirements in the Boiler Room
Let Your Equipment Breath! Successful, efficient combustion requires three items: heat, fuel, and air. When designing a boiler room, the supply air needed can easily be overlooked. Boiler room supply air is the proper amount of air required for equipment to operate most effectively, including ventilation air. Without adequate air supply sizing, boiler room equipment can become inefficient, and […]
Pressure Atomized API-AF Burners
Pressure atomization depends on the oil pressure inside the nozzle tip to spray a fine mist of oil, very similar to a Windex spray bottle. The micronized oil droplets are flung into the burner head, where they are thoroughly mixed with the combustion air and ignited. As mentioned above, the pressure at the oil nozzle is the key […]
Why Oxygen Trim Should Be Part of Your Boiler Room
by Joe Wallace Oxygen trim (O2 Trim) is a system that constantly monitors your boiler’s combustion. Unlike your car, your boiler has the ability to run properly without it, so what are the upsides to it? This system can adjust your air fuel ratio based on what it’s supposed to be and triggers alarms or lockouts should the […]
