INTRODUCTION
Power projects are essentially capital intensive. Not only they involve a highly initial cost which is around Rs. 4.5 to 5.0 crores per MW for coal-based plants but also huge operation cost. The running expenses of a 210MW thermal power station may range around thirty crores every month and usually about 80% of this goes towards the fuel cost. Not only fuel cost but also fuel crises increasing day to day. It is therefore, very important that one gets the best performances from the installed power plants. The first criterion of performance is the plant output. Failure in generating the maximum output from the power plant implies a default in realizing the full return from the huge capital investment made for constructing the plant. Performance degradation by 1KW from a generating unit implies a net loss of about 1.2 lacks incurred over the plant operating life. The performance criterion that receives considerable attention is the plant heat rate. An increase in heat rate by a mere 1kcal/kwh reflects into direct increase in fuel cost by about Rs.20000 per day for 210MW thermal power plant. Boiler performance, the one of the main cause of heat rate deterioration from design value as its efficiency and evaporation ratio reduces with time due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.
OBJECTIVE
The objective of present study is as follows
To observe the effect of different quality of coal on boiler performance as well as on unit performance.
To study the boiler efficiency and unit heat rate by using the running parameter and investigate the various cause of performance degradation from design value.
To study the effect of HPHs on boiler and overall unit performance.
To study the effect of
