A continuous dry particulate matter injection device (), 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 (), suitable for feeding particulate matter, and connected, by a first connection pipe (), to the top of a vertically positioned slurry mixing chamber (), located under the first connection pipe (), and a pressurized mixing tank (), connected to the bottom of the slurry mixing chamber () by a second connection pipe (). The device is operated in a continuous cycle.

Continuous dry particulate matter injection device for fertigation applications

The present invention relates to the use of a double salt of Ca(NO)and KNOfor 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 NaNO, KNOand Ca(NO), preferably, an eutectic ternary melt comprising Ca(NO), NaNOand KNOin a weight ratio of about 42:15:43 with an operating temperature of about 131&#xb0; C. to about 560&#xb0; C.
