Abstract
In a thermal power plant, the boiler is a portion responsible of converting incoming water into steam which is followed by various apparatus which turn it to super heated steam. This steam is supplied to steam turbines. The dryer the incoming steam greater is the efficiency of the turbines and greater is the electricity produced. The general issue with the incoming water to the boiler is it is filled dissolved gases, very tiny particles and other stuff that damage the boiler and the adjoining apparatus. The presence of these cause damage to the boiler and other devices on the longer run and reduce their lifestyle. Even a single replacement of the boiler coupled with other apparatus can cause exaggerating expenditure. In general, the apparatus attached with a boiler are super heaters, steam turbines and condensate pump. The dissolved gases present in water can react with the walls of these, form oxides, and corrode them. With time, the walls of these devices develop cracks and hence loose their working capability. This project comes up with a pre set apparatus before water is let to the boiler. This set up cleans the water of all visible impurities so that they are not deposited at any point in the whole process. Next, it goes ahead and gets rid of most of the dissolved gases present that have chances of reacting with the boiler or other following apparatus following boiler. In this way, a sure and reliable set up can be installed to improve the lifetime of the apparatus used in the power plant. This will end up saving cost at a very high level. This project depicts and explains such a set up and uses SCADA to present its functioning. With the help of SCADA, this system becomes foolproof by installing artificial intelligence by the use of sensors and alarms. The alarms are set for critical and normal use values and it is also described in the project. The SCADA would be aimed at reading critical data like water analysis, system analysis, water flow, water levels etc.
