Steam Boiler SCADA
Steam boiler plays a vital and crucial role in manufacturing plants of white goods ,semiconductor & process industries as its products steam are important source of thermal energy.The steam at constant temperature and pressure are used in many manufacturing processes like semiconductor fabrication,sterlization.Steam is used in many santization and cleaning process.
to achieve high level of productivity the metered/measured water is fed at controlled pressure & fanmotor operation ,burner operation is monitored to produce the steam at monitored pressure ,the amount of PNG consumed is logged & the amount of steam produced is also logged using flowmeter,conected to the analog input of the PLC which is conencted to the SCADA software using ethernet cable.
Scada for the boiler
The application involved monitoring the efficency of three no of steam boilers at client site
Sensors on the boiler
Instruments like pressure Transmitter ,Temperature transmitters,Flow transmitters are mounted on the output side of the boiler steam line.
The input water flowrate & consumption gets logged in the SCADA using flowmeter of endress and hauser.
PNG flowmeter
Fuel to these boilers were PNG
the fuel consumption to the boilers was monitored and logged on the SCADA through PLC analog inputs
We were able to measure the flowrate of the PNG and totalizer value which was logged in the scada ,to calculate the daily,weekly and monthly usage of PNG against the steam produced in the same duration.
It was usefull for the client to compute the bolier efficiency.
PLC panel with analog inputs
Mitsubishi PLC FX5U along with analog inputs was used to
the fuel consumption to the boilers was monitored and logged on the SCADA through PLC analog inputs
Real time Trends of Steam PNG,Water
Real time Trends
real time trends of the water consumption ,PNG consumption ,Steam produced,Temperature of the steam.
Historic trends of the all parameters are stored for the analysis & records.
