THE HYDRODYNAMIC PARAMETERS OF OPERATION OF DEAERATORS WITH NATURAL GAS
Assesses the main hydrodynamic conditions for efficient operation of the deaerator makeup water of the district heating systems in the application of new technology of low-temperature degassing of the water. The technology involves the use introduced as a Stripping agent is water vapor does not contain in its composition of oxygen and carbon dioxide reduced natural gas with low temperature (10-30°C) supplied to the furnaces of boilers of thermal power plants and boilers. A new method of aeration provides a significant increase in energy efficiency for preparation of makeup water heating systems in cogeneration power plants. To assess the practical applicability of the new technology made the calculation of the gas velocity in the holes of the bubble sheet the deaerator. Determined by the height of the gas cushion under bubble sheet, providing not a failure operation mode of the sheet. The calculated gas velocity in the deaerating head, which ensures absence of brythonia from the deaerator through the pipeline in front of the burner of the steam boiler plant. It is shown that in the operation of domestic commercially available inkjet-bubble deaerator atmospheric type using as a working medium natural gas provided the required hydrodynamic conditions of the basic elements of the deaerator.
