Prepare your Facility for Cold Weather: Combustion Air Requirements
Parts of the United States have experienced and continue to experience unusually cold temperatures over the last two weeks. In these circumstances, plant operators are usually forced to shut windows and doors in their boiler rooms to keep the cold air out and prevent water lines from freezing. But boilers need to breathe too. Bottling up a boiler […]
Prepare your Facility for Cold Weather: Thermopump System
The cold front predicted for next week may bring some of the coldest temperatures seen in the United States since 1936. It will affect areas as far south as Houston and San Antonio. These are areas where plants are not designed with the capability to heat their diesel fuel during cold weather—because weather this cold doesn’t happen very […]

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 […]
