A pot furnace for calcining petroleum coke at low temperature may include a pot, and a cooling water jacket and a flame path below the pot. The flame path may include eight layers. An inlet of a first flame path layer may be in communication with a volatile channel in the front wall, and is provided with a first flame path layer flashboard. An eighth flame path layer may be in communication with a communication flue. Flue gas may be discharged out of the furnace body through a main flue. A furnace bottom cooling channel may be provided below the eighth flame path layer.

A heating device with a heat conducting element and an evaporation system using the same are provided. The heating device includes a crucible, a heat conducting element and a heating element. The crucible includes a bottom surface, an opening opposite to the bottom surface and an accommodation space for accommodating a to-be-evaporated material. The heat conducting element is disposed in the accommodation space of the crucible and disposed on the bottom surface and extending towards the opening. The heating element is disposed adjacent to the crucible.

A powder feeder system for a foundry system having a mixing hearth includes a housing assembly, and a feeder assembly in the housing assembly having a moveable barrel feeder for feeding a pre-weighed charge of metal powder into the mixing hearth of the foundry system during operation thereof. A method for recycling metal powder includes the steps of melting a content of the mixing hearth completely; and then feeding the metal powder into the mixing hearth while the contents of the mixing hearth are still molten using the powder feeder system.

An ion implanter includes a crucible provided inside a vacuum chamber, and including an internal space configured to accommodate a solid sample which is a raw material of a source gas, a laser source provided outside the vacuum chamber, and irradiating the crucible with a laser beam, an arc chamber including an internal space for converting the source gas into plasma to generate ions, and in which an ion beam is extracted from the internal space, and a nozzle connecting the internal space of the crucible and the internal space of the arc chamber, and introducing the source gas vaporized in the internal space of the crucible into the internal space of the arc chamber.

A blast furnace operation method according to one aspect of the present invention includes: a process of acquiring a correlation between a carbon consumption in reducing gas and a reduction InputΔC in specific carbon consumption caused by blowing the reducing gas into the blast furnace per molar ratio C/H of carbon atoms to hydrogen atoms in the reducing gas; a process of determining a carbon consumption in the reducing gas where the reduction InputΔC in specific carbon consumption is a predetermined target value or higher on the basis of the correlation acquired per C/H; and a process of adjusting the amount of the reducing gas blown into the blast furnace on the basis of the determined carbon consumption in the reducing gas and the carbon proportion in the reducing gas.

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.
