METHOD FOR DETERMINING ELECTRICAL LOSSES OF A POWER LINE, DUE TO A MALFUNCTIONING OR TAMPERING OF AN ELECTRICITY METER AND/OR TO AN ILLEGAL CONNECTION TO SAID POWER LINE
The present invention relates to a method which allows to determine electrical losses of at least one power line (100) due to a malfunctioning or tampering of an electricity meter and/or to an illegal connection to said power line, through the statistical analysis and the processing of measured data, taking into account of the powers absorbed by a plurality of users (U1,U2... UN) connected to said power line (100) and the power supplied from a transformer room (1) to said power line (100) measured by a power meter (10), positioned on said power line (100), between said transformer room (1) and the users of said plurality of users (U1,U2... UN). In particular, the method object of the present invention allows to identify one or more users whose respective electricity meter is malfunctioning or tampered, as well as the presence of a possible illegal connection to the power line, where said malfunctioning or tampered electricity meter and said possible illegal connection cause electrical losses of said power line. The present invention relates also to a system for determining said electrical losses.
The invention relates to an assembly (50) comprising an evaporative cooler (20) and an evaporator (63), wherein the evaporative cooler (20) is suitable for treating a flow of gas (G) and comprises a means (21) for spraying an aqueous mixture (MA) into the flow of gas (G); a basin (22) suitable for allowing settling and storage of a quantity of aqueous mixture (MA) in the condensed state; a recirculation circuit (23) suitable for removing the aqueous mixture (MA) from the basin (22) and supplying it to the spraying means (21) of the evaporative cooler (20); and a bleeder pipe (24) suitable for removing the condensed pollutants from the bottom of the basin (22) and conveying them externally; and wherein the evaporator (63) comprises a line (61) for supplying a flow of oxygenated gas (A); means (630) for spraying an aqueous mixture (MA) into the flow of oxygenated gas (A); a pipe (65) suitable for removing a quantity of aqueous mixture (MA) from the basin (22) of the evaporative cooler (20) and for supplying the aqueous mixture (MA) to the spraying means (630); a line (62') suitable for conveying the wet oxygenated gas (All) externally.
The invention relates to an apparatus 10 for cleaning the gas G produced by a gasifier 12 of biomass. The apparatus comprises: an input line for conveying the gas G from the gasifier; a scrubber 20 for treating the gas G; a wet electrostatic precipitator 40 for treating the gas already treated by the scrubber 20; and an output line 18 for conveying the gas G to an external user unit. The apparatus also comprises cooling means 50 for removing a further quantity of heat from the gas G be fore i t is conveyed to the external user unit. The cooling means 50 are positioned between the first scrubber 20 and the wet electrostatic precipitator 40. The invention also relates lo a plant 100 comprising a gasifier 12, an apparatus 10 and an external user unit.

F26B 25/04 - Agitating, stirring, or scraping devices
The invention relates to a plant (100) for the gasification of biomass. It comprises a gasifier (10) and an apparatus (23) for the filtration of the gas. The apparatus comprises a scrubber (31), a tank (41), and a wet electrostatic precipitator (51). The scrubber is in fluid communication with the gasifier and with the tank, and is adapted for the injection of a washing liquid in the gas flow. The tank comprises a bottom area adapted for collecting the liquid and a top area adapted for holding the gas, separated by gravity. The wet electrostatic precipitator is in fluid communication with the top area of the tank, so as to receiving only the gas. The invention further relates to a gasifier comprising a gasification reactor (12), a grate (125) for the support of the biomass in the reactor (12) and a plug (126) for closing the middle part of the grate. The plug is vertically movable so as to close and/or open the middle part of the grate.
