ANALYSIS OF BOILER EFFICIENCY– CASE 1.0 INTRODUCTION Looking to the statically data, rate which power demand increases is extremely very high compared to the rate at which generation capacity increase. Boiler is a heart of power develop a broadly useful finding the methods of Boiler efficiency of Thermal Powerboiler mass and energy balance calculation. Boiler efficiency The boiler efficiencyis a measure of the goodness of the chosen process and equipment to transfer the combustion heat to the heat in steam. For the best solid fuel boilers, the boiler efficiencyis 86 90% . Oil and natural gas firedboilers can achieve 90 94%

Fuel flow and heat input are not used to calculate boiler efficiency, but Boiler Calculations for Steam, Hot Water and Thermal boiler calculations Chat Online1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like 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.
Boiler Efficiency is of prime importance to the process plants. Improving the boiler efficiency even slightly can cut down the fuel bills significantly. Improvement in boiler efficiency can be achieved if certain steps are followed.

INTRODUCTION Boiler is a steam producing equipment, which produce steam with burning of fuel. Mostly coal is used as fuel in boiler. Efficiency of the boiler should be determined by two method, direct methodBoiler Efficiency: Introduction and Methods of Calculation It is a well known fact that the initial cost of boiler is a small part of total costs associated with the boiler over its lifetime. In the operational life of a boiler, major costs arise out of the fuel costs.
This paper presents briefly on the boiler efficiency evaluation procedures by direct and indirect methods useful in thermal power plants. In the direct method consideration is given to the amount of heat utilized while evaluating the efficiency of the boiler, whereas, indirect method accounts for various heat losses. The boiler efficiency evaluated by direct method is found to be lower thanEfficiency studies of combination tube boilers. Author Testing of the boiler efficiency calculates the best possible efficiency, which drifts away from the test efficiency. Therefore, corrective action could be taken, to rectify the observed problem areas, for achieving the best efficiency. There are two methods
