application case of boiler
application introductionthe former boiler system mainly uses dampers or valves to control the flow rate of blower, induced draft fan, make-up water pump, and circulating pump and has the following disadvantages: its design did not take energy saving into consideration; the steam demand varies with production process and task. the coal feeding (oil injection) amount should be changed to achieve high-efficiency burning. traditional methods using manual operation have disadvantages of high energy consumption, low control accuracy, high requirements for worker’s skill. there is a common problem with boiler system: one boiler is insufficient but two boilers are too many. the boiler frequency converter is mainly used to control the blower, induced draft fan, make-up water pump, circulating pump, coal feeder, pulverizer, etc. of boiler system. now, frequency converters have been widely used by boiler systems in paper making, food, forging, petrochemical, dyeing & finishing, chemical, pharmaceutical, grease, marine products, and other industries.
process characteristic
·starting stably has small impact force for power grid.
·with the function of rotate speed tracking, it can realize dynamic start-up.
·setting pid function inside can realize automatic closed-loop control.
·with the function of rs-485 communication function, it can meet the needs of quantization and networking for boiler system.
·with good over-load capacity and resistance for bad environment, it can operate stably in the long run.
applicable scenario
similar application: coal fired boiler, gas fired boiler
applicable industries: thermal power, metallurgy, petrochemistry, heating, paper making, food, forging, dyeing, pharmacy, grease, marine products processing
