ABSTRACT:
A mounting structure for a chemical injection tube for geothermal wells utilized for power generation from geothermal energy. A chemical injection tube is extended into a geothermal well, having an upper end fastened by a sealing flange and a lower end extending down below the flashing point in the well, wherein scale inhibiting chemicals can be supplied from the ground and injected through the tube directly to the geothermal fluid in the well. Thus, the chemical injection tube facilitates the prevention of carbonate scale deposition in the well and results in a stable power plant operation.
