:- Industrialization is increasing every day and there is a great need for industry energy assessment audits. To maintain and save energy from being wasted and help in achieving highest efficiency of industrial equipment, audit plays a very crucial role. This paper carries a carefully prepared industry audit report on boiler operations and performance. Basically this paper deals with the study on Thermal analysis of boilers, thermal skin heat loss of boilers, O2 percentage control in flue gases to standard values, effect of coal additive, etc. This paper also contains a report on waste heat recovery options for thermal boilers. Vane type Anemometer, Glass type Thermometer, Flue efficiency monitor, infrared thermometer, ultrasonic peak detector, IR thermal imager, these equipment are used for energy assessment of boilers. To estimate the radiation and the other losses, a thermography survey of the boiler surface is carried out and it reveals total annual savings after insulation repairing or maintenance is Rs.8.48 lakh and investment is around Rs.6.31 lakh. With the help of suggested measures Economizer performance of both the ISGEC and Thermax boiler can be improved. It will help to save approximately rupees Rs.38.42 Lakh annually and investment on maintenance cost is negligible. Assessment of all boilers, calculate their efficiencies and losses to measure energy saving areas and present them as recommendations with their payback periods is carried out in this paper
