Power plant efficiency and combustion optimization
Grasim, a leader producer of Rayon grade staple fiber has, with time come up with its own Captive Electric Power Generation Industry with a capacity of generating 113 MW Thermal Power for its in-house use involving state of the art technology and system. In the present paper, it is desired to share the technical development in the global environment and receive expert feedback for its own upgrade. The on site power plants have a variety of steam turbines and boilers of different capacities. At times the plants had to face power crisis due to number of reasons and has always come up with number of solutions for performance enhancement and efficiency improvement. It is desired to present the following cases: (1) Development of spiral coal caps--for atmospheric fluidized bed boilers, it is often experienced that unburned carbon is high in ash. The reason being that coal particles do not get sufficient retention time after being injected into the bed. Attempt has been made to increase the retention time and better mixing by creating a cyclone around the coal cap with help of spiral coal caps. (2) Combustion optimization--in view of the inherent design deficiency, combustion was optimized by controlling the three parameters i.e., time, temperature and turbulence. In pulverized fuel combustion boilers this was done by providing air damper regulation and in atmospheric fluidized bed combustion boilers this was done by creating a vortex and regulating fluidizing air. The details shall be given in paper. (3) Power plant efficiency improvement--by introducing online monitoring system and identifying various areas of losses for various operating reasons and the cost associated with each operating parameter and the impact of each variation.
