Boiler Efficiency Analysis

EEI is concerned with calculating boiler efficiency as one of the vital performance measurement in any steam power plant. The aim of monitoring boiler performance is to control the heat rate of plant. Our initiative is in determination of operating efficiency of boiler and calculate major losses any power plant.

The heat rate of a conventional coal fired power plant is a measure of how efficiently it converts the energy contained in the fuel into power energy. In the operational life of a boiler ensuring efficient operation of boiler is critical to optimize the fuel costs. Boilers efficiency is based on various factors. Mostly it doesn’t work at its rated efficiency; it has been found that boilers operate at much lower than the rated efficiencies if efficiency monitoring is not done. Boiler efficiency is a combined result of efficiencies of different equipment of a boiler.

EEI experts check the boiler combustion efficiency and thermal efficiency of the boiler and boiler components.

The combustion efficiency of a boiler is the indication of burner’s ability to burn fuel and the thermal efficiency of a boiler indicates the effectiveness of the transfer of heat from heat exchanger to boiler tubes. Thermal efficiency will be badly affected by scale formation/soot formation on the boiler tubes.

The other parameters which will also be checked by EEI consultants are the on-off losses, radiation losses, convection losses, blow down losses which have a direct or indirect impact on the efficiency of the boiler performance.

Monitoring and maintaining the boiler for the overall operational life of the boiler is a must for the profitability of the organisation.

Boiler and Boiler Components Residual Life Assessment

EEI method of automated on-site system eradicates delays, misconception and human errors and is finest technique to detect hydrogen damage zone.

EEI consultants evaluate the present condition of pressure parts & piping to avoid premature pressure parts failure and associated unforeseen outages. We also identify the problem areas, and check the root cause of problems.

EEI experts give estimation of balance life of pressure parts.

Residual Life Assessment (RLA) is important to maintain the efficient operation of a process plant and avoid failure of critical equipment like pressure vessels, piping, storage tank, valves, pumps, compressors, boilers, turbine which lead to losses because of the downtime. RLA is a statutory requirement as per IBR regulation “391A”,

Our consultants adopt various methods for residual life assessment which includes review of past data, visual and dimensional inspection of the boilers and equipment, micro controlled ultrasonic test and dye-penetration test of high temperature headers & piping, hardness measurement, replication for metallography, oxide scale thickness measurement of the inside the tube using micro controlled UT, video scope examination, sampling of the tube and laboratory testing, locating hot spots.

EEI consultants RLA ensure that the organization is informed early about failures and cost effective method is carried out to reduce the risk of catastrophic failures. RLA allows advanced outage planning.
