Übersetzung für "Burned lime" in Deutsch

This solid mixture contains chiefly excess burned lime and fly ash as well as calcium chloride and iron compounds.

Lime is burned in ancient lime-burn kilns and then slaked in lime-pits.

After it has cooled down, the burned lime is sorted into different particle sizes and stored for further processing.

Limestone is burned in a lime kiln to a temperature between 800 and 1200 °C.

This admixture is especially effective if the two adsorbents have been produced together from the start (e.g. by slaking of the burned lime under the addition of hydrochloric acid).

Stones were burned in the lime ovens to produce quicklime which once slaked was used to cover walls.

For increasing the Ca content e.g., but not exclusively, Portlandite Ca(OH) 2 or burned lime, ashes with high chemical CaO and/or free lime content, cement clinker and granulated blast furnace slag are suitable.

Nevertheless, there are a few highlights to be discovered: Our ancestors burned lime stones in the lime kilns, the Brechelofen ovens were used to break down flax so it could be used for making cloth.

To burn the lime he had coal mined in the Deister hills.

The peoples will be like the burning of lime, like thorns that are cut down and burned in the fire.

And the people shall be as the burnings of lime: as thorns cut up shall they be burned in the fire.

The fuel costs for lime burning are considerable and may account for more than 50% of the production costs.

Because lime burning was still in not fully developed, the builders mixed the mortar with horsehair, quark, goat's milk and ox blood to harden it fully.

SUMMARY OF THE INVENTION In accordance with the invention, this object is achieved in that the gas forming during charging of the scrap into the metallurgical meltdown vessel and during heating and melting of the scrap, after conditioning to a temperature range of between 1000° and 1500° C., is used as a heating gas in a lime-burning process with a moving lime fixed-bed under release of its sensible heat, wherein sulfur and chlorine containing components of the heating gas ar absorbed on the burnt lime and the dust contained in the heating ga is separated in the lime fixed-bed and the heating gas, which is purified and cooled at its passage through the lime fixed-bed, subsequently is finally purified in a filtering plant.

Since dioxines and furans already are formed at relatively low temperatures, the offgas forming in the preheating of scrap outside of the metallurgical meltdown vessel suitably is mixed with the gas forming within the metallurgical vessel during melting of the scrap and, together with the same, is used as a heating gas in the lime burning process.

According to a particularly advantageous embodiment, the dust incurred in the filtering plant, together with the dust and fine lime incurred in the lime burning process, is recycled into the meltdown vessel as a slag former, suitably is blown into the meltdown vessel.

Although shaft constructions for the burning of cement, lime, gipsum or the like are known (DE-PS 31 932) in which the shaft interior is subdivided by grids which are laterally withdrawable through the shaft walls in order to convey the material to be calcined level by level through the shaft, such shaft, because of the complete filling of the chambers with the bulk material does not permit a uniform flow through the material or a uniform transfer procedure between the gas and the bulk material particles, quite apart from the fact that a feeding of the bulk material, level by level, through the shaft interior is virtually impossible when the chambers are filled completely.

Already in 1766 the landlord prohibited lime burning on the island, because he wished to save the forests of Vormsi.
