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.

Abstract: A crematory loader apparatus is provided for loading objects to be incinerated into a preheated crematory. The loader has a frame along with a slidable support surface attached to the frame for supporting an object thereon which slides in a track supporting the slidable top surface during sliding of the top surface between a first position for loading the object onto the slidable support surface and a second position canterlevering the slidable support surface into the crematory. A plurality of legs are attached to the frame and support the frame and the slidable support surface.

Abstract: An auxiliary incinerator apparatus for a crematory includes a main incinerator having primary and secondary chambers formed with a plurality of refractory walls and a main door into the primary chamber. The main incinerator has an outer framework with wall attached thereto and spaced from the refractory walls. The refractory passageway extends from the primary chamber refractory wall to the outer wall. An auxiliary incinerator is attached to the side of the main incinerator outer wall and framework, adjacent to the opening from the refractory passageway through the wall. The auxiliary incinerator has an incineration chamber formed therein with a top opening thereinto. An auxiliary door simultaneously opens and closes over the opening from the refractory passageway through the outer wall and over the opening into the auxiliary incinerator, so that partially incinerated materials can be moved from the main incinerator to the auxiliary incinerator for further combustion.

Abstract: An apparatus to induce drafts in combustion chamber stacks can operate at temperatures from 1400.degree. to 2600.degree. while being fabricated from mild steel with refractory lining. The induced draft apparatus includes an exhaust stack connected to a combustion chamber and has an annular plenum formed around the base of the stack with a narrowed annular outlet from the plenum into the stack. An air blower is connected to the annular plenum for directing air under pressure thereinto and into the stack at a predetermined position. An annular refractory surface is formed on the inside of the plenum wall in the stack and the stack is similarly lined with a refractory material.
