Heat recovery

》Energy recovery with hot water

   The production of compressed air consumes a lot of energy, of which 94% of the energy consumed is converted into heat and discharged through heat exchange equipment. Through the heat exchange technology, we can recover the heat energy of the compressor in the form of hot water, and we can greatly reduce fuel consumption and carbon dioxide emissions, saving a lot of energy and expenses.

                        ■      Oil-injected screw compressors can recover 75% of energy consumption

》Steam turbine driven compressor

Power plants and large chemical plants generally have their own power plants. By-product steam can be used for steam turbines to drive large compressors. Turbine driving has a higher energy consumption rate than motor driving: the motor is driven by the steam from the boiler first. It is necessary to supply the motor to drive the air compressor after power generation by the steam turbine of the power plant; the drive of the steam turbine can reduce the loss in the energy conversion process and improve the energy utilization.

      Conducive to the balance of steam consumption in power plants, effectively reducing energy consumption costs

       Reduce the power grid requirements for electric drive start of large compressors and reduce the cost of starting devices

       It is convenient for variable load adjustment of large compressors, and overcomes the difficulty that large motors are not suitable for frequency conversion adjustment
