Tarmac International Inc. Launches 30-NOx Burner with PLC Controller
Tarmac International Inc., Lee’s Summit, Missouri, launched its new 30-NOx burner with PLC controller at WOA 2022. The burner features two fuel valves—a primary in the back and a secondary in the center. “We pre-mix the fuel and air early,” President Ron Heap said. The burner uses early mixing of fuel and air along with internal gas recirculation to reduce NOx from over 100 PPM down to 30 PPM. This 30 PPM NOx is a level that Tarmac’s customers are experiencing in the USA.
The new burner controller allows for improved fuel and air valve positioning (parallel positioning) with both manual and auto control. An Allen Bradley PLC with 10-inch touch screen controls the burner and interlocks. Manual operators are seen for backup control should the PLC fail. There is a “dashboard” where management can see burner production, fuel per ton, position of the fuel and air valves, position of the ID fan, negative pressure of the burner faceplate. Over-the-phone service is available with the technician seeing the parameters of the burner controller.
