The production line includes a curing oven, a fluidized bed reactor including an exhaust gas duct, an inlet for predetermined primary fuel, an inlet for predetermined bed material, and an outlet for an ash material, the ash material including bottom ash discharged via a bottom outlet from the fluidized bed reactor or fly ash separated by a particle separator from exhaust gas in the exhaust gas duct or a mixture of the bottom ash and the fly ash.

Test dummy for detecting at least one process variable in the manufacture of glassware of identical or similar design along a production line, comprising a base body which is adapted to the shape and/or dimension of the glassware in such a manner that it can pass through the production line instead of a glassware, at least one sensor system mounted on the base body for detecting the at least one process variable on the base body, and at least one transmission apparatus mounted on the base body for transmitting the at least one detected process variable to a digital receiving unit.

A recycling production line for horseshoe-fired-melting-furnace waste glass is provided, which includes a pre-flushing mechanism used for cleaning, a secondary cleaning mechanism and a drying mechanism. Two conveying mechanisms are mounted at a lower end of the pre-flushing mechanism and a lower end of the drying mechanism, respectively. The secondary cleaning mechanism is arranged between the two conveying mechanisms. An oscillating mechanism is arranged between the pre-flushing mechanism and the conveying mechanism. Through the cooperation of the pre-flushing mechanism and the oscillating mechanism, when glass cullet is flushed for the first time, the effective vibration force and the flushing force can be provided, the cleaning effect is guaranteed, water resources can be recycled, and energy resources are saved. The ultrasonic cleaning, and the drying that is performed at a drying temperature with temperature ranges are utilized, to improve the cleaning degree for later use.

The present disclosure provides a solidifying method of a radionuclide. The solidifying method of the radionuclide includes operations of: providing a low melting point glass including Bi.sub.2O.sub.3, B.sub.2O.sub.3, ZnO and SiO.sub.2; providing a glass mixture mixing a mixture to be treated containing a hydroxide of radionuclide and BaSO.sub.4 and the low melting point glass; and heating the glass mixture.

A sealing system for isolating the environment inside a vitrification container from the outside environment comprises a vitrification container with a lid. The lid comprises two or more electrode seal assemblies through which two or more electrodes may be operatively positioned and extend down through the lid into the vitrification container. The electrodes may move axially up and down through the electrode seal assemblies or lock into place. The electrode seal assemblies each comprise a housing having two halves with recessed ring grooves. Sealing rings with a split may be placed into the grooves. Gas galleries may be machined or cast into the housing such that they are adjacent to the ring grooves. The gas galleries distribute gas onto the external faces of the sealing rings causing a change in pressure resulting in the sealing rings compressing onto the electrodes and forming a seal.

Described herein is a method of forming a smelting byproduct that can be formed into an inorganic fiber, the method comprising: a) introducing silicomanganese slag and a smelting additive into a submerged arc furnace comprising a collection zone; b) smelting the silicomanganese slag into a silicomanganese metal and a smelting byproduct, whereby the silicomanganese metal settles to a lower portion of the collection zone and the smelting byproduct gathers in an upper portion of the collection zone due to density differential between the silicomanganese metal and the smelting byproduct; c) flowing the smelting byproduct from the collection zone from a first outlet; and d) flowing the silicomanganese metal from the collection zone from a second outlet.
