Abstract
This work deals with the assessment of operational and design efficiency of the power plant to promote efficient working while ensuring a degree of obedience with legal guidelines and targets to recognize the operational flaws related with operational parameter in power plant process. Plant efficiency and losses during the process are the main parameters for any power plant. A large amount of energy resources are used in the boiler used for the process or power plant. Although boiler provides energy in the form of steam obtained from fuel, a large number of fuel energy is wasted in form of different losses occurred that can be saved through effective utilization of fuel, which will affect the efficiency of boiler and CO2 emission reductions as well.
In this thesis, 03 models for boiler, steam turbine and power plants are applied on the pulverized coal-fired power plant to examine the efficiency. Model 01 is based on a direct efficiency method, which is the simplest. In this method ratio of steam and fuel heat was calculated to examine the boiler efficiency, which is 82.63%. Model 02 is based on heat loss method in which individual loss from the boiler was calculated to inspect the efficiency of boiler that was 82.76% and the major losses in this model were due to dry flue gas, moisture in fuel and moisture in the air. Model 03 is designed as per guidelines of ASME PTC-4 method in which heat losses and heat credits were calculated to determine the actual efficiency of plant that was 82.48%. Results of steam turbine and overall plant efficiency were the same for all models, which were 34.58% and 30.74% respectively.
