This paper outlines the various
stages of operation involved in the conversion of a
manually operated boiler towards a fully
automated boiler. Over the years the demand for
high quality, greater efficiency and automated
machines has increased in this globalised world.
The initial phase of the paper focuses on passing
the inputs to the boiler at a required temperature,
so as to constantly maintain a particular
temperature in the boiler. The Air preheater and
Economizer helps in this process. And the paper
mainly focuses on level, pressure and flow control
at the various stages of the boiler plant. Thus the
temperature in the boiler is constantly monitored
and brought to a constant temperature as required
by the power plant.
The automation is further
enhanced by constant monitoring using SCADA
screen which is connected to the PLC by means of
communication cable. By means of tag values set to
various variable in SCADA the entire process is
controlled as required. At the automated power
plant, the boiler is controlled by Variable
Frequency Drive (VFD) to put in action the
required processes to be carried out at the boiler.
Thus the entire cycle is carried out as a paper and
at various stages each phase is detailed out. This
paper has proved to be very efficient practically as
the need for automation grows day by day.
