Pallet Manufacturer Forced to Upgrade Furnaces
 Needed to Meet EPA Clean Air Act Requirements
PROBLEM: An Illinois pallet manufacturing company discarded old, broken pallets by burning them in an incinerator. Burning occurred at least twice a week producing heavy concentrations of smoke. In order to meet compliance with the Clean Air Act, the company had to reduce the emissions generated from the furnace. However, purchasing two new furnaces would obviously have been a major capital expenditure.
SOLUTION: The solution: spray nozzles. In fact, three different models of spray nozzles were used: UniJet® blow-off nozzles, WhirlJet® nozzles and FullJet® nozzles.
Six stainless steel UniJet blow-off nozzles were installed in the fire box of the incinerator. The use of Blow-off nozzles intensifies the fire and efficiently burns the pallets. The nozzles are connected to an air line with a separate filter and pressure gauge.
In addition, eight FullJet nozzles were also installed in the fire box. Since the smoke concentration is heaviest in the fire box, the FullJet nozzles' large drops are effective in cleaning the smoke. The particulates that aren't "washed down" by the FullJet nozzles then pass through a series of six WhirlJet nozzles. Both the FullJet nozzles and WhirlJet nozzles are connected to a water line with a liquid strainer and its own pressure regulator and gauge.
The installation of these spray nozzles met the stringent EPA requirements. Plus, the spray nozzles were a very economical solution versus having to purchase an expensive new furnace.
