ABSTRACT:
An incinerator apparatus has a primary incinerator chamber which has a secondary incinerator chamber coupled thereto by a passageway. The primary incinerator chamber has a primary air input into the incinerator chamber and the secondary air chamber has a secondary air input thereinto having a plurality of air input lines with each line having an electric motor control valve, such as a damper motor controlling a damper valve controlling the flow through one of the input lines. A plurality of ultraviolet flame detector ports open into the side of the secondary incinerator chamber, each being spaced a predetermined distance from each other and each having a ultraviolet flame detector positioned therein for sensing the ultraviolet radiation and the flame adjacent the detector in the secondary incinerator chamber. Each ultraviolet flame detector is operatively coupled through electronic controls which includes relays to actuate each of the plurality of electric damper motors to open and close the damper valve responsive to the ultraviolet flame detector signal thereby the secondary air flow is controlled by a flame detector reading the flame position at a plurality of points in the secondary incinerator chamber. One air blower can direct the air to the primary chamber and to the secondary chamber through a plurality of ports into each chamber with the secondary air being increased or decreased responsive to the length of the flame in the secondary chamber to thereby maintain the temperature within a predetermined range within the secondary chamber to ensure complete combustion of the incinerated product.
