The present invention relates to a method for reducing or preventing the decomposition of a composition Z comprising Z1 a salt of dithionous acid in an amount ranging from 50 to 100 wt % and optionally Z2 an additive selected from the group consisting of alkali metal carbonate, alkaline earth metal carbonate, alkali metal or alkaline earth metal tripolyphosphate (NaPO), alkali metal or alkaline earth metal sulfite, disulfite or sulfate, dextrose and complexing agents in a combined amount ranging from 0.0001 to 40 wt %, which comprises contacting the components Z1 and optionally Z2 in the solid and/or dry or solvent-dissolved or -suspended state with at least one of the following compounds V in the solid and/or dry or solvent-dissolved or -suspended state, wherein the compounds V are selected from the group consisting of: (a) oxides of the alkali metals lithium, sodium, potassium, rubidium, cesium, or of magnesium, (b) sodium tetrahydroborate (NaBH), (c) anhydrous copper(II) sulfate (Cu(SO)), phosphorus pentoxide and (d) basic amino acids arginine, lysine, histidine, wherein the solvent for Z1, optionally Z2 and V is practically water-free.

Stabilization of sodium dithionite by means of various additives

The invention relates to a device for storing heat, comprising a heat storage medium which absorbs heat in order to store heat and releases heat in order to use the stored heat, and a container for holding the heat storage medium, the container being closed by a gastight cover, and the device comprising volume compensation means in order to compensate for a volume increase of the heat storage medium () due to a temperature rise and a volume decrease due to a temperature reduction. The invention furthermore relates to a method for storing heat, in which heat is transferred to a heat storage medium in order to store heat or heat is discharged from the heat storage medium to the heat carrier in order to use the heat, the heat storage medium being held in a container which is closed by a gastight cover, wherein a volume expansion of the heat storage medium () is compensated for by a volume increase of the container () or by heat storage medium () flowing out of the container () into a buffer container (), and a volume decrease of the heat storage medium () is compensated for by a volume decrease of the container () or by heat storage medium () flowing out of the buffer container () into the container ().

Device and method for storing heat

Described is a pipeline system for conveying a salt melt, comprising at least one pipeline () through which the salt melt flows, at least one inlet and at least one outlet, wherein the pipeline () through which the salt melt flows has at least one gradient inclined with respect to the horizontal and is respectively connected at the lowest positions via a drainage valve () to a drainage line () and at the highest positions to a venting valve (). Also described is a method for draining the pipeline system.

Pipeline system and method for draining a pipeline system

The invention relates to an apparatus for heating a pipeline system, comprising at least two pipelines (), along which in each case one electrical resistance heating element extends, wherein a potential close to the ground potential is set at each electrical resistance heating element at at least one end (), and the electrical resistance heating element is connected to a terminal of a DC source or to in each case one phase () of an n-phase AC source () at a position remote from this end (), where, when using an n-phase AC source (), n is an integer equal to or greater than 2.

Apparatus for heating a pipeline

The invention relates to a pipeline for carrying a molten salt, with a pipe wall that is stable with respect to the temperatures occurring. A heating conductor () is provided inside the pipeline () for heating, the heating conductor () preferably not lying against the inner wall of the pipeline ().
