BOPI 12 BR/2023 REPERTOIRE NUMERIQUE 24 (73) CNIM ENVIRONNEMENT & ENERGIE SERVICES, 35 rue de Bassano, 75008 Paris (FR) (74) AFRIC'INTEL CONSULTING, Essos, Immeuble Mah Dong Véronique, 2nd floor, B.P. 8451, YAOUNDE (CM). (57) The present invention relates to a process for cleaning a boiler, wherein, while fumes (F) are emitted in a combustion chamber (C) of the boiler and circulate up to exchangers of the boiler, an aqueous solution (S) of dissolved magnesium chloride and/or sulfate and/or dissolved calcium chloride is injected into the combustion chamber in the form of droplets which, by vaporization of the water of the aqueous solution, then thermal decomposition, are transformed in the combustion chamber into magnesium and/or calcium oxide particles reacting in the combustion chamber by mixing with molten salts and/or molten oxides, present in the fumes, to crystallize these molten salts and/or to vitrify these molten oxides before these molten salts and/or these molten oxides come into contact with the exchangers. The invention also relates to a device for implementing this process and a boiler equipped with this device.

NGWAFOR & PARTNERS SARL, The House of Gideon, Golf/Bastos Quarter, Opposite The American Embassy, Entrance-Saint John Paul II Boulevard, B.P. 8211, YAOUNDE (CM). (57) The present invention discloses designating two different treatment /ones in a large body of water. The first zone is a sedimentation zone. This zone is used mainly to provide treatment and settling of microorganisms and/or contaminants to inactivate and/or remove them from die water body. In this zone a disinfection method based on a CT index and applying an efficient amount of a flocculant composition may be used. The second zone is a dissipation /one. This zone is where main direct contact recreational water activities are intended to occur. In the dissipation zone a water flow is established that, along with the natural currents produced by winds and/or water temperature differences, generate a water dissipation pattern of the volume of water within the dissipation zone into the sedimentation zone. In addition, continuous disinfection of the water volume in the dissipation zone is preferably provided by maintaining a permanent chlorine residual.
