North American Manufacturing Co., Ltd.'s new 4408 VHPI Variable Heat Pattern Injector Burner provides a new dimension to the firing flexibility and performance of roof-fired tunnel kilns. Unlike conventional injector burners, which release the fuel's energy according to the shape of their fixed flame envelope, the VHPI allows the user to dynamically move the energy release location in the vertical plane between the top of the load and the deck. VHPI provides a much more uniform heating profile, which results in a better temperature gradient throughout the product. Benefits of this new product include reduction in required firing time, increased production via push rate increase and improved fuel efficiency via reduced push duration.
