DESCRIPTION:
A boiler system is an integral component of a process plant, and control of the
water level and temperature of the water in the drum of the boiler system is a critical
operational consideration. The major dynamics of boiler water level includes
nonlinearities, non-minimum phase behavior, instabilities, and time delay and load
disturbances. A low water level in the drum will cause loss of flow of water to tubes
and causes its overheating leading to subsequent failure, A high water level will cause
water to be carried over into the turbines and causing it failure due to thermal stress
problem. Due to interaction of the steam flow and changing pressure in the drum, the
water level can be difficult to control and typically requires sophisticated control
techniques. Therefore accurate water level measurement must be made and
temperature of the water in the drum.
The objective of this project is to provide a combination of manual supervision
and partial automation and is similar to manual set-up in most respects but it reduces
the labor involved in terms of Irrigation design is simple, easy to install,
microcontroller-based circuit to monitor the values of water level and temperature of
the thermal plant boiler that are continuously modified and controlled. Here we are
using ADC to convert the analog values of temperature into digital and these values
are given to microcontroller as input and it will be displayed on LCD.
But by using this scenario we can have the knowledge of the liquid present in
the drum and there is an indication and also if there is an any overflow of liquid is
also indicated using buzzer, with the help of microcontroller. The status of the project
is displayed on LCD.
