SPECIFIC FEATURES OF THE APPLICATION OF STEAM JET COMPRESSORS FOR PNEUMATIC SUPPLY OF AIRLIFTS OF HYDRAULIC ASHREMOVAL SYSTEMS
The article presents an analysis of the energy efficiency of the operation of pneumatic supply systems for airlifts of hydraulic ash and slag removal systems of thermal power plants and the results of experimental studies to substantiate the possibility of using gas (steam) jet compressors as sources of pneumatic energy for these devices. To compare the energy indicators of the system for supplying the air-lifts with pneumatic energy from radial blowers with an electric drive and the option of the power supply system for the same lifts from steam-jet compressors, energy consumption in both cases is reduced to the consumption of primary equivalent fuel. The use of a steam-jet compressor as a source of pneumatic energy significantly reduces the technological chain of converting the chemical energy of the fuel into the energy of the working fluid for the airlift, which provides almost equal value of the energy efficiency of the operation of these power supply systems for hydropneumatic lifts in thermal power plants. Experimentalstudies substantiated the possibility of using steam-jet compressors as sources of pneumatic energy for airlifts of hydraulic ash removal systems, as providing the required pressures and flow rates of gaseous working bodies for hydropneumatic lifts.
