ESTIMATION OF POWER GENERATION CAPACITY OF NON WOODY BIOMASS AND COAL BIOMASS MIXED FUEL SAMPLS AND THEIR ENERGY VALUES

Abstract

On account of environmental problems and energy with reference to fossil fuels/non renewable resources (coal, petroleum and gas) in the production of power, a greater focus is being given worldwide by technocrats and scientists and researcher for consumption of renewable energy/fossil fuels sources or reusable energy sources in the generation/production of power, metallurgical factories and so further There exists a variety of inexhaustible energy sources out of which biomass is the most financially feasible source for most parts of the world. Biomass is a carbonous material which serves the purpose of not only producing thermal energy but also reduction of oxides, while other inexhaustible energy sources only render to the former. Out of all the solid fuels, biomass is a homogenous fuel containing low levels of ash. According to India’s renewable energy sources’ power generation potential data, biomass has the capacity to produce higher than 18000 MW of electricity in an year. However, our territory hasn’t completely succeeded in the efficient and judicious utilization of Biomass as it could produce merely 2000 MW (approx.) of electricity in a year despite the Indian Government introducing incentives for the same. Therefore, it is imperative to take prudent measures in order for biomass to be utilized in rational terms and extract its benefits in an environment friendly manner. The existing venture work is a supportive venture towards vitality and ecological issues confronting the planet. The currently chosen agro-forestry biomass species have no materialistic use and are less utilized. Co-firing of biomass fuel and coal has been proven to be an increasingly effective and a pocket friendly technique for the generation of power. For this study, non-cooking coal arranged locally and the related biomass species were mixed in different ratios to make briquettes (coal;biomass = 95.00:05.00, 90.00:10.00, 85.00:15.00, 80.00:20.00). The objective was to evaluate their values of energy and potential to generate power. The experimental work executed for this thesis has been dealt with in the third chapter which includes ascertaining the proximate analysis, heating value and ash fusion temperature (AFT) of various elements of biomass, non coking coal & their combination. The study concluded that Biomass species of Cassia Tora have somewhat higher ash contents and low fixed carbon contents along with lower energy values. On the other hand, Page | iii Gulmohar biomass species were seen to have comparatively lower ash contents and higher fixed carbon contents while the Energy values were found to be relatively tad higher. The result of the proximate analysis of the chosen and studied coal shows it of F-grade. Apparently, a rise in the biomass content (nascent branch/wood/leaf) leads to a rise in the values of energy in the resulting briquettes. While considering both Volatile Matter (VM) and Fixed Carbon(FC) results, this gives the idea of the unstable/volatile matter substance impact the vitality estimations of the briquettes alongside settled carbon. Out of the four AFTs (IDT, ST, HT and FT), softening the powder's temperature holds essential significance for the evaporator operation. It has been proven by the results that both the species of biomass have somewhat the same temperature for the purpose of softening but relatively reduced when compared to coal. It was observed that a rise in the content of biomass in the briquette (Coal+Biomass) being studied had trivially lowered the softening temperature which showed that it was safe to operate the boiler up to approximately 1100 0C. The establishment procured from this project work is furnished in Chap. 4 of the dissertation.
