3. Coal Efficiency Coal Efficiency represents the amount of Energy that can be extracted from a single unit of Coal. So, we are essentially talking about Plant Efficiency, or more specifically Combustion Efficiency; which can be measured to see what amount of Energy is being extracted from a single unit of Coal in a particular system.

4. Combustion Efficiency Combustion Efficiency is a measure of how efficiently a device/system consumes fuel. Ideally, it should be 100%, meaning that the fuel is completely consumed. In practice, this level of efficiency is impossible to achieve, but it's possible to come close. The lower the combustion efficiency, the less efficient the device is, making it expensive to run, wasteful of fuel, and harmful for the environment.

5. Factors affecting Combustion Efficiency and Overall Plant Performance Poor Combustion Excess Air control Deviation of fuel quality from designed values Heat Transfer Fouling Pre-water treatment Condenser Performance APH Performance Poor Operation and Maintenance of Boilers

6. Methods used to overcome these problems Scheduled Maintenance and AOH of Boilers. Modification and Renovation in the Boilers Energy Audit to keep an account of various losses in Boilers. Different types of analysis like CFD Analysis to improve flue Gas Path.

7. Disadvantages of employing these methods High Capital Expenditure Shutdown required Complexity of these methods Highly skilled Professionals required For analysis purpose, expensive equipment required.

8. Alternative ??? Then, Is there any solution which is - Simple in Application, Involves no Downtime, and Requires no Capital Expense ?

9. Combustion Catalysts Coal Additives

10. Effective Additive – Reduction in Losses, Impact on GUHR & Boiler Efficiency 1% Red’n in UFA – 20 Kcal/kwh on GUHR & 0.8% in Boiler Eff. 1% Red’n in UBA – 2.5 Kcal/kwh on GUHR & 0.2% in Boiler Eff. 1% Red’n in Excess Air – 7.4 Kcal/kwh on GUHR & 0.6% in Boiler Eff. 1% Red’n in FGT – 1.2 Kcal/kwh on GUHR & 0.067% in Boiler Eff. 1TPH Red’n in S/H Attemp. – 0.03 kcal/Kwh on GUHR 1TPH Red’n in R/H Attemp. – 0.25 kcal/Kwh on GUHR 1 mm of soot deposit Red’n – 0.83 % savings in Coal (Ref :- BEE, NTPC, IGEN, BS 2885) Thus, due to improvement in all above parameters, with the use of an effective Additive, 2 to 4 % savings in coal can be achieved.

60. Effective in all types of Boiler Depending on the Boiler type, size, age, operational conditions, fuel used, maintenance practices, renovations done with time, its Efficiency varies. In a set of ideal conditions it may also be close to Designed efficiency. But still, with Additive use, there is always scope of improvement in its Efficiency and in turn reduction in Coal Consumption.

68. Test Significance: This is a statutory test required for products being used/ imported into USA which detects the presence of potential hazardous chemicals to human/ environment/ ground water. About 95 different elements are identified as hazardous to humans, environment and ground water. Test Results: The test conducted by SGS Lab on THERMACT confirms that none of the 95 identified hazardous chemicals are present in THERMACT. Test Inference: The use of THERMACT is safe and does not cause any detrimental effect on humans/ environment. SGS TEST REPORT Abhitech Energycon Ltd.

69. CENTRAL MECHANICAL ENGINEERING RESEARCH INSTITUTE, DURGAPUR (CMERI) CMERI has investigated the effect of prolonged usage of THERMACT (5 years and above) on boiler tubes at Bandel TPS. Test Results: CMERI has studied the conditions of the boiler tubes at BTPS after THERMACT was used for more than 6 years. They have carried out dimensional measurements of boiler tubes by various methods like Visual Inspection, Chemical Analysis of the 2 Metallographic Examination and Hardness Measurement, Tensile Property Evaluation, Stress Test and Fractographic Examination. Test Conclusion: CMERI has confirmed that even after a prolonged usage of THERMACT for more than 5 years, there is no detrimental effect on the metallurgy of the boiler tubes and various pressure parts. Abhitech Energycon Ltd.

72. CONCLUSION: In view of all the investigations completed as per scope of work (mainly visual examination, dimensional measurement, chemical analysis, metallographic analysis, hardness and tensile test results), no noticeable material degradation of the exposed tubes supplied) under the influence of THERMACT is being observed. Apart from that long term behavioral study from stress rupture tests also do not reveal an significant abnormality. Moreover, attempts were made to confirm the effect of “THERMACT” on the surface and sub-surface characteristics of the tubes using SEM and EDS analysis (as an optional test) also did not depict any harmful effects. Hence, it seems to be prudent to declare that THERMACT, as a compound to enhance the heat efficiency within the furnace, does not loose any detrimental threat to the life of boiler tubes. However, it is wise to state that this is valid only when all the mandatory inspection schedule of boiler tubing is maintained as per the guidelines.

73. CENTRAL MINING RESEARCH INSTITUTE, DHANBAD (CMRI) Test Significance: This test states the impact of THERMACT on the combustion characteristics of coal. Test Results: Confirm that addition of THERMACT catalyst improves the combustibility of coal. Abhitech Energycon Ltd.
