iNDVS 500 series inverter power energy-saving boiler

Recently, the success of INDVS 500 series inverter to realize energy-saving boiler equipment of Shenzhen textile enterprises. INDVS 500 inverter used in boiler 37KW blower and 18.5kw cited fan, after the completion of the transformation and measure, the blower and the induced draft fan of frequency conversion transformation after power-saving rate is as high as 45%, saving a lot of operating costs for customers.

In all kinds of civil and industrial boiler thermal automatic control process, the automatic control of the boiler combustion process is an important control content. In the traditional control methods, drum, induced draft fan of the air flow generally use the damper control, grate motor and powder feeder with slip speed, its malpractice is not timely adjust, complex operation, waste of energy and can not ensure the boiler optimum operating state. The frequency conversion speed regulation of the industrial boiler combustion process is mainly through the frequency converter to adjust the feed rate and the lead of the fan.

Fan pump type load is based on the full load of work needs to type selection, the actual application in most of the time is not working in full load condition. Because the AC motor is very difficult to adjust, the use of the wind board, return valve or open / stop time, to adjust the air flow or flow. At the same time, it is difficult to drive / stop frequently in the power frequency state, which will cause the electric energy loss and the current impact when the power is on or off. Inverter direct control of the fan, the load is one of the most scientific control method, when the motor at the rated speed of 80% run, energy efficiency can be as high as 40%. In addition, because of the frequency converter can realize large motor soft stop, soft, avoid the start of the impulse voltage, reduce the failure rate of the motor, to extend the service life, but also reduces capacity requirements on the grid and reactive power loss.

INDVS technology has been committed to the professional leading drive zero carbon energy saving control technology development, to build a green intelligent high energy environment and create a healthy happy and wonderful life and make unremitting efforts.
