---------------------------------------------------------------------***--------------------------------------------------------------------fuels do fill the gap between the energy consumption and Abstract- Electrical energy is crucial for dairy industry since
energy production [1] and also Effective energy management in dairy industry will help to save electricity, benefiting the utility, customer and society as a whole. In the event of a power grid failure, immediate access of electrical energy is essential for critical loads. Diesel generators are commonly installed in all dairy industry to provide backup power, as they can be started and stopped quickly without any issues. However, the availability of diesel is depleting, costly and causing environmental pollution, there is a need to find alternative solutions to reduce reliance on diesel consumption and maintain reserves for future needs. Biomass gasification is one of the most efficient way to convert the energy submerged in biomass. In the long term, the use of this new technology will reduce the too-high pressure on natural resources, especially in developing countries [2] Lowering the compression ratio and introducing a combustion system that utilizes spark plugs can enable diesel engines to operate using producer gas. Another approach is to run the diesel engine in dual fuel mode, where the engine uses diesel for 0 to 80% of its output power while using producer gas. An additional 20% of diesel is needed to ignite the fuel mixture. In the event of a failure or malfunction of the above methods, the engine can revert to normal diesel operation. This provides added flexibility and reliability [3]. 75 KVA biomass gasifier was demonstrated that, the dual fuel gasifier can be operated for 465 hours, out of which 190 hours continuously. The gasifier was operated automatically 24 hours a day & only small adjustments of the feeding rate were necessary once or twice a day. The operation was successful, and the output was as expected [4].
milk is susceptive to degradation. To meet the increasing demand, the clean and sustainable energy the biomass is being considered as an alternative sustainable renewable energy source. Among the various methods for biomass conversion, biomass gasification is a key process for converting biomass into gaseous fuel for heat and electrical power generation. This research paper delves into the estimation and analysis of electrical energy consumption in the dairy industry and evaluates the economic feasibility of integrating biomass gasifiers with the existing diesel generator for both OFF and ON Grid applications. The study was carried out at Chitradurga Davanagere Shimoga Milk Union Limited (CHIDASHIMUL) dairy industry, Machanahalli, Shimoga district, Karnataka, India. The findings of the study and analysis indicate that the annual electrical energy consumption of dairy industry is 35,42,800 units. By integrating a 1500 KVA biomass gasifier with the existing 1500 KVA Diesel generator, the diesel consumption is reduced by 80 % and supplies power to the ON/OFF grid. Further, by installing 1500 KVA biomass gasifier, the estimated running cost savings is Rs 15 Lakhs/annum and payback period is 9 years. Additionally, CO2 emissions are projected to decrease by 43 tonnes/annum. The study results were shared with the Chitradurga Devanagere Shimoga Milk Union Limited dairy industry for their consideration regarding implementation. Keywords- Biomass Gasifiers, CO2 emission, Dairy industry, Payback period.
1. Introduction The CHIDASHIMUL dairy industry is located at Machanahalli, Shimoga district, Karnataka, India, handles 2,50,000 liters of milk per day, consumes an average electrical energy of 2,95,000 units/month. CHIDASHIMUL dairy industry has an annual turnover of Rs.1,03,509 Crore during the year 202324 with an annual electrical energy charges of Rs 8.5 crores. In dairy Industry paramount importance in supplying milk daily to the publics and in providing income for farmers. Large quantity of milk need to be processed, packed, stored and distributed every day, requiring a significant amount of electrical energy. Energy is largely dependent on the fossil

This research work explores the integration of Biomass gasifier with existing diesel generator in dual fuel mode. This technology aims to reduce pollution and provide economic benefits and also Fixed bed gasifiers are the most studied and suitable reactors for biomass gasification due to their simple operation and easy construction [13]. A case study was conducted at CHIDASHIMUL dairy industry, Shimoga district, Karnataka, India, where primary data is collected. The primary data includes the technical specifications of the existing diesel generator set such as KVA rating, rated
