Protection of heat exchangers from salt deposit in the process of utilization of methane from geothermal water
https://doi.org/10.15518/isjaee.2023.04.027-034
Abstract
The article deals with the issue of operation of heat exchangers in the mode without scaling when using geothermal waters in the heating and hot water supply system. The possibility of simultaneous utilization of methane from water with the preservation of the equilibrium concentration of carbon dioxide in it is estimated. A technique is proposed for periodic dissolution of carbonate deposits in a heat exchanger, formed when carbon dioxide balance is disturbed in a solution of geothermal water. At the same time, a relationship has been established between the concentration of carbon dioxide in water and the time of dissolution of previously formed deposits of calcium carbonate in the heat exchanger. This makes it possible to evaluate the decrease in heat losses with a decrease in heat transfer coefficients in the heat exchanger during the dissolution process. A schematic solution is given for the integrated development of the energy of geothermal water sources, in which the protection of power equipment from carbonate deposits is carried out by the combustion products of utilized methane.
