GREENHOUSE OPERATION METHOD Russian patent published in 2020 - IPC A01G9/24 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and can be used in greenhouses. Method of greenhouse operation consists in supply of water, fuel and air into boiler. In the boiler, fuel is burnt with formation of combustion products and heating of water flow, which is directed to heating system of greenhouse tent. Second water stream is heated in condensation surface waste heat exchanger installed in the main gas duct and connected via water path to underground greenhouse heating system. Combustion products cooled to dew point in condensation surface waste heat is heated in mixing chamber and discharged to atmosphere. Part of carbon dioxide-laden combustion products before discharge to atmosphere is supplied to gas distribution system of greenhouse. Condensate discharged from combustion products is removed during cooling down to dew point. Additionally, greenhouse is equipped with tank-tank for collection of desalinated water - condensate of water vapours generated in heat exchanger-waste heat from outlet products of natural gas combustion in process of their cooling below dew point, to which the pump is connected and connected on the delivery side by a pipeline to an irrigation device located in the hothouse of the greenhouse. Periodically, through the pipeline, desalinated water is supplied from the tank-tank into the sprinkler device and by means of nozzles installed on the sprinkling device, uniform desalination of desalinated water into space of greenhouse tent to humidify air and watering soil of greenhouse tent with desalinated water.

EFFECT: this will make it possible to increase efficiency and economy of greenhouse operation.
