Claim:
1. A modular installation for carrying out a method of manufacturing an explosive emulsion precursor constituted by a water-in-oil reverse emulsion, the method comprising: a) a step of preparing an aqueous phase by dissolving nitrates in water and heating; b) a step of preparing an oily phase by mixing components comprising at least one vegetable and/or mineral fat and a surfactant, and heating; and c) a step of preparing said emulsion by mixing said aqueous phase into said oily phase, the modular installation comprising at least: a first container for preparing the aqueous phase, said first container including a first dissolution tank provided with first heater means and first stirrer means capable of heating and stirring the aqueous phase contained in the first container, wherein the first container includes a first rectangular tank with at least five walls arranged against and parallel to the respective at least five walls of said first container, said first heater means for said first tank comprising a first tube heat exchanger, said first tube heat exchanger being constituted by a network of continuous heat transfer fluid cylindrical transfer lines arranged longitudinally and transversely at different heights, which are capable of heating the liquid contained in said first rectangular tank by distributing the heat from the heat transfer fluid circulating in said network of lines throughout the volume of said first tank, wherein said cylindrical longitudinal lines are arranged substantially at the same height, and connected together at their ends on the same side by line elements forming horizontal transverse connectors, one end of at least one longitudinal line arranged at a given height being connected to the end of a longitudinal line arranged at a lower or higher height via at least one vertical bend line element.
