Abstract
A mounting structure for chemical injection tube for a geothermal well which is used to generate power from geothermal energy is provided. A chemical injection tube is wound spirally along the outer surface of a vertical pipe. A double structure of a casing pipe of the geothermal well including the injection tube, which is inserted between the pipes, extends deep in the well below, the flashing point of the well. A plug is inserted at the lower end of the tube. The plug is removed by compressed air or water prior to the injection of scale inhibiting chemicals from the top of the tube. Thus, the chemical injection tube protects the well from the deposition of carbonate scale thereby providing a stable power plant operation.
