A melting kettle for processing of thermoplastic material. The kettle disclosed herein obtains heat transfer by use of an oil jacketed tank with an adjoining main tank for storage of hot oil and a hose tank for recovery of the hot oil. Oil expelled from the oil jacket is directed to the main tank through an opening. Spillage of oil from the hose tank is directed to the main tank through an aperture. The melting kettle reduces the space needed for oil storage, and increases operator safety by eliminating additional transfer lines. Dual kettles benefit by having the adjoining main tank placed therebetween.

A crucible device includes a heating chamber, at least a first crucible in which a first crystal is growable, and at least a second crucible in which a second crystal is growable. The first crucible and the second crucible are arranged within the heating chamber spaced apart from each other along a horizontal and vertical and any orientational direction. The crucible device further comprises a heating system arranged within the heating chamber, wherein the heating system is configured for adjusting a temperature along the horizontal and vertical and any orientational directions.

Melting kettles for use on vehicles for continuous processing of material for applying lines, stripes, bitumen, crack sealant or the like. The kettles disclosed herein provide heat transfer by use of oil jacketed tanks. A coil may be placed along a lower section for heat transfer through a burner for heating recirculated oil. A coil may be placed in a lower section and an upper section for heating an oil jacket, as well as heat transfer from the entire circumference of a coil placed in the upper section. An upper coil can be fluidly coupled to a lower coil and positioned within the chamber a spaced apart distance from the interior wall of the melter kettle. A mixer system rotates paddles to cause continuous transfer of material around the upper coil. The melter kettle is cylindrical, but can be corrugated to increase heatable surface area.

An example mobile kiln system includes a mobile platform. A frame is mounted to the mobile platform. At least one kiln is rotatably mounted to the frame. The kiln is movable between a first operational position for loading a feed material into the at least one kiln, and a second operational position for unloading a biochar product from the at least one kiln following processing of the feed material. In an example, the mobile kiln system includes at least one stack assembly for the kiln. The stack assembly has a lid to cover the kiln to retain heat and a chimney to release emissions from the kiln during processing of the feed material.
