    Abstract: A flame intensity controller for controlling the air/gas mixture introduced into a conveying and/or mixing tube. Plural heating arrays are transversely aligned to the direction of movement to dry the moving web. The controller selectively controls the heating intensity of each section of the heating arrays to thereby control the amount of drying experienced by each longitudinal section of the web. The controller may be a countercurrent air controller or a mechanical restrictor. The energy output of each section is controlled between adjustable upper and lower energy levels. However, the lower energy level is chosen to be sufficient to sustain combustion. The independent control of the dryer sections provides dramatic improvement in uniformity of the moisture "profile" across the web.

    Abstract: A burner assembly provides for 100% premixing of fuel and air by drawing the air into at least one high velocity stream of fuel without power assist. Specifically, the nozzle assembly for injecting the fuel into a throat comprises a plurality of nozzles in a generally circular array. Preferably, swirl is imparted to the air/fuel mixture by angling the nozzles. The diffuser comprises a conical primary diffuser followed by a cusp diffuser.

    Abstract: In some examples, a gas/air mixing device configured to mix gas and air to provide a gas/air mixture includes a mixer housing with a mounting flange being configured to mount the gas/air mixing device to a fan housing in such a way that a sealing surface of the mounting flange is in contact with a sealing surface of the fan housing. In some examples, the sealing surface of the mounting flange has grooves with a second radius being different from the first radius. In some examples, the sealing surface of the fan housing has a groove, with a second radius being different from the first radius. The mixer housing provides an inlet opening for air, an inlet opening for gas, and an outlet opening for the gas/air mixture. The sealing surface of the mounting flange surrounds the outlet opening of the mixer housing.

    Abstract: A premix burner apparatus includes a burner structure and a firing rate control system. The burner structure defines a premix reaction zone configured to communicate with a process chamber. The burner structure further defines a plurality of separate entrances to the reaction zone, and a corresponding plurality of separate premix flow paths, each of which is configured to direct both oxidant and fuel to a respective one of the entrances to the reaction zone. The firing rate control system is operative to control flows of oxidant and fuel along at least one of the flow paths separately from flows of oxidant and fuel along at least one other flow path.
