DESIGNING OF POWER GENERATION PLANT FROM LANDFILL GAS ( BIO FUEL)[ ]


Energy from renewables has been sought to replace current fossil fuel energy generation. Landfilling is one of the most commonly adopted technologies for Municipal Solid Waste (MSW) disposal as an alternative to waste burning and composting. Landfill gas (LFG) mostly results from the anaerobic decomposition of biodegradable fraction. . Landfill gas is a mixture of several gases with its main constituents being methane and carbon dioxide. Landfill gas can be collected by either passive gas collection system or active gas collection system, both of which consist of gas collection wells that provide a preferential migration route for the landfill gas. Landfill gas utilization is a process of gathering, processing, and treating the methane gas emitted from decomposing garbage to produce electricity, heat, fuels, and various chemical compounds. Landfill gas has great potential to generate power since it contains methane 40 to 60%. Utilizing an enhanced landfill gas as fuel for power generator is also beneficial to reduce greenhouse gas emission from landfill otherwise it will escape to the atmosphere. Current technology in power generation from landfill gas includes organic Rankine cycle (ORC) and Stirling cycle engine (SCE) to add the traditional reciprocating Internal Combustion Engine (ICE) and Gas Turbine (GT).

EXPERIMENTAL STUDY OF PARTIAL REPLACEMENT OF COARSE AGGREGATE WITH COCONUT SHELL AND LATHE SCRAP IN CONCRETE[ ]


Using coconut shell (CS) as replacement should be urged as a priority in environmental concerns and construction cost lowering measure. The stainless-steel scrap material which is usually available in lathe industries are used in modern construction and likewise in pavement construction. Lathe waste are generated by each lathe industry, in addition to discarding of these waste materials into barren dirt also contaminates the soil and ground water, which generates an unhealthy atmosphere. The rising cost of structural material is a different concern. The explanation for enhance in cost is large demand of concrete in excess to scarcity of raw materials. Hence many researchers are focusing on technique of using waste materials in concrete as to their properties. In this particular study, M25 grade of concrete was prepared by replacing coconut shell for coarse aggregate and in addition of lathe scrap to cement. Natural resources such as coarse aggregate and fine aggregate are depleting in a shocking rate within developing nations like India. The options of using coconut shell aggregates in concrete as rough aggregate is examined inside the present study. Coarse aggregate is replaced by 3%, 6%, 9% of coconut shell in conventional aggregate. With the water - cement ratio being kept regular as 0.45 and cement have been replaced with lathe waste by 0.5% & 1%. Tests were carried out to find the compressive strength, split tensile strength and flexural strength using cube, cylinder and beam specimens respectively.The results show that a new possible exists for the usage of coconut shells as replacement of regular aggregate in the conventional concrete and light-weight RC construction

STUDY ON STRUCTURAL ANALYSIS AND DESIGN OF RCC BIN[ ]


Storage is one of the essential and vital stages between the marketing and consumption phases. Reinforced cement concrete (RCC) is an ideal structural material for building of permanent bulk storage facilities. RCC Bin can be flat bottom type or hopper bottom type. Though flat bottom bins can be built more easily than hopper bottom bins but it is desirable that bottom is self cleaning. It is due to this reason that hopper bottom bins are preferred. Specified the various parameters such as height of bin, diameter of bin, properties of the material to be stored ( angle of repose and density), grade of steel, grade of concrete, the number of supports, and the components are designed. For every single case, support numbers have been varied in multiple of 2, starting from 4say4, 6, 8, 10, 12etc. Conforming to the usual practice, the supports are assumed to be equally spaced alongside the periphery. For the designed components (ring girder dimensions, column cross-section, thickness of wall ), depending upon height &diameter of the bins, mass matrix and influence coefficient matrix is then generated. The, parameters such as fundamental natural frequency and other frequencies in first 3 modes for bin full and bin empty conditions have been computed and the normalized Eigen values have been computed corresponding to first 3 modes. Further, dynamic & static analysis of bins has been carried out by taking elements at 2m interval both in bin (full & empty) conditions. Then the values of natural frequencies and elemental matrices along with normalized mode shape values are used in carrying out dynamic analysis.

EXPERIMENTAL INVESTIGATION ON REINFORCED CEMENT CONCRETE COMPRESSION MEMBER WITH PARTIAL REPLACEMENT OF CEMENT BY GGBS[ ]


The increasing search for alternative sustainable and eco-friendly construction materials has led to research on various replacement materials in concrete that have properties similar to that of cement. The concept of partial replacement of cement that is capable for sustainable development is characterized by application of industrial wastes to reduce consumption of natural resources and energy and pollution of the environment. GGBS a by-product in pig iron manufacture has been found to be an ideal material to replace ordinary Portland cement used in concrete and it improves the durability of concrete. GGBS slag is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ground Granulated Blast Furnace Slag (GGBS) was partially replaced as 0%, 10%, 20%, 30%, and 40% in place of cement in concrete. Concrete are made for M -30 mix and the cubes, cylinders and prisms are casted for 7, 14 & 28 days of ages and based on the testes conducted on these specimens the 30% replacement is found to be the optimum percentage of replacement of GGBS in concrete. In this study the comparison of conventional RCC column and 30% GGBS RCC column are analysed. The columns are casted for 28 days of curing and tested. It is found that normal M30 grade concrete fails to sustain the compressive strength as compared to the M30 grade concrete prepared by partial replacement of cement by GGBS.
