Utilisation of waste heat of thermal power plants - using heater tubes laid into topmost soil layers in open air or in greenhouses

摘要

The exhaust heat of thermal power plants or industrial plants is utilised by feeding warm water in pipelines into greenhouses surfaces. The heater tubes (3) are laid into a topmost soil layer fixed with chemical or physical means to strip-shaped components. Alternatively, the heating tubes (3) are laid in soil-covering layers (1) of suitable material which has good thermal conductivity. The layers (1) have an incline normal to their longitudinal axis. Plants are planted in recesses (4) in the strip-shaped components or in the soil covering layers.
