The boiler drum level control with Drum levelControl System in thermal power station, with some modification is taken as a project work and the paper presentation is given below. Boiler is a machine that produces steam from the water resulting from combustion of fuels such as fibre, coal, black oil, gas, and diesel. Commonly in industry they use PLC to move all operations of Boiler system.If the drum level goes below the desired lower drum level, there will be a every possibility of starvation of water tubes inside the furnace is expected and the boiler may get damaged and if the water level in the drum raises above the desired upper drum level, there will be a carryover of water particles in the dry steam flowing to the turbine and thus the turbine blade damage is expected. In order to meet out the steam requirement , to safeguard the boiler water tubes and to safe guard the turbine blades the boiler drum water level control plays an important role in thermal power station.The main objective of the boiler–turbine system control is to meet the load demand of electric power while maintaining the pressure and water level in the drum within tolerances. The advanced control algorithm is derived for changing function of single element to three element transfer, which is Wide Fast Combination of batch and continuous type operations. Here we used the wide opening technology for conservation of the energy.In this project the total Drum level, feed water and steam flow are controlled by using microcontroller PIC 16F877A.
