Industrial wood fired boiler emission control is an example of a dry electrostatic precipitator installation. In a plywood manufacturing plant in Alabama, boiler emission control is achieved with the replacement of a wet scrubber, increasing air flow to 132,000 ACFM. Pollutants were wood ash. In British Columbia, boiler emission control at a plywood and lumber company were achieved with the installation on an elevated structure of steel. Air flow increased to 120,000 ACFM. Other examples of dry electrostatic precipitator system installations that regulate emissions include a Glass Bottle Manufacturing Facility, a Cogeneration plant, Refining plant and pulp and paper industry. Environmental compliance is always necessary.
