Abstract: The present invention relates to the use of a double salt of Ca(NO3)2 and KNO3 for the manufacture of a melt, in particular a nitrate-based heat transfer fluid (HTF) and/or thermal energy storage fluid, for example in solar energy applications, such as in solar electrical power plant systems using a parabolic through, a central receiver or a linear Fresnel, which have both a low melting temperature and a high decomposition temperature, as well as to methods for the manufacture thereof. Using said double salt, a melt could be manufactured comprising at least NaNO3, KNO3 and Ca(NO3)2, preferably, an eutectic ternary melt comprising Ca(NO3)2, NaNO3 and KNO3 in a weight ratio of about 42:15:43 with an operating temperature of about 131° C. to about 560° C.

Abstract: A continuous dry particulate matter injection device (1), and more in particular a device for use in a fertigation application in which a soluble matter, such as a fertilizer, is suspended and/or dissolved into the irrigation water in order to use the irrigation system and irrigation water as a delivery system for the soluble matter, in particular a soluble fertilizer. To this end, the device includes at least one feed device (2), suitable for feeding particulate matter, and connected, by a first connection pipe (3), to the top of a vertically positioned slurry mixing chamber (5), located under the first connection pipe (3), and a pressurized mixing tank (12), connected to the bottom of the slurry mixing chamber (5) by a second connection pipe (8). The device is operated in a continuous cycle.
