ECONOMICAL BENEFITS WHAT IS BIOMASS? THERMAL APPLICATION basis, or in multiples thereof, including Biomass Gasifier system. CFA of Rs.2.00 lakh per 300 kWth on pro-rata basis, or in multiples there of for S.No Application Description Biomass is organic material, which has stored solar Like any other gaseous fuel, producer gas has the Thermal Application. CFA is available for village electrification also. 1. 100% Producer gas Approximately 1.2kg of wood will energy from sunlight in the form of chemical in the advantage of better and finer power control, more based power produce 1 unit of electricity, which plants through the process called photo synthesis. efficient and environment friendly when compared to PROCESS generation costs Rs. 1.25 and the operation & 3 Biomass fuels include Agricultural Wastes, Crop that of solid fuels. Burning of 1 m of Producer gas in the maintenance cost will be around Chopped wood (Biomass) is fed into the top of the reactor. The reactor Residues, Wood, Woody Wastes & Organic Wastes etc. burner will release thermal energy of the order of 4.5 to Rs. 0.5/-. Totally it cost around 0 Unless like fossil fuels Biomass does not add carbon 5.0 MJ. Flame temperatures as high as 1200 C can be we install is Open Top, Twin air entry, IISc design. After ignition, when Rs. 1.80/- per Kwh. (unit) whereas dioxide to the atmosphere as it absorbs the same obtained by optimal pre-mixing of air with producer gas. the biomass flows down, it undergoes chemical changes there by gives E.B. Tariff of Rs. 4.75 per Unit amount of carbon while growing. It is the cheapest, For processes, which require thermal energy, gasifiers out the volatile matters of the wood in a gaseous form. This product is 2. Duel Fuel mode One unit of electricity is produced eco-friendly, renewable source of energy. can be a good option as a gas generator, and retrofitted known as producer gas. This gas is separated from the gas separation power generation using 0.9 kg of wood +50ml of unit and taken to the cooling and cleaning equipments. The residue from with existing devices. Few of the applications are: diesel. Totally it cost around the reaction ash and charcoal is removed by a screw conveyor WHAT IS BIOMASS Rs. 2.65/- per Kwh. (unit) whereas Dryers: Drying is the most essential process in industry connected to the bottom of the reactor. The gas is washed and cooled in GASIFICATION? E.B. Tariff of Rs. 4.75 per Unit. like tea, rubber, cardamom etc. It requires hot gases in the scrubbers arranged in series to improve the gas quality. The gas 0 3. Thermal application Approximately 4 kg of biomass can the range of 120 - 130 C. Gasifier could be an ideal further treated in the chilled water scrubber where due to the water Biomass Gasification converts solid biomass into more replace 1 litre of HFO / Diesel in solution for the above situation, where hot gas after temperature the tar particles present in the gas get condensed and convenient gaseous form. The ratio of air-to-fuel thermal energy. Approximately combustion can be diluted with the required quantity of separated from the gas. The purified gas passed through fabric filters. required for the complete combustion of the biomass is Biomass @ Rs. 4/- can replace secondary air, so as to lower its temperature to the These filters enhance the quality of the gas further. 6:1 to 6.5:1, which defined as stoichiometric HFO @ Rs. 25/- and Diesel @35/-. desired level for operation. combustion with the end products being CO and H O. Thereby resulting a cost saving of 22 The cooled, purified and filtered gas suitably mixed with air in proper Rs. 20/- and Rs. 30/- respectively. In gasification the combustion is carried at sub- Kilns: Baking of tiles, potteries require temperature composition in the carburetor and enters into the engine. The engine stoichiometric conditions with air-to-fuel ratio being range of 800 - 950 0C. In conventional practices they runs like a petrol engine. The exhaust gas comes out from the engine OTHER BENEFITS 1.5:1 to 1.8:1. The gas so obtained is called producer burn large quantities of wood in an inefficient manner. fed into a drier where we recover the exhaust gas temperature for drying gas, which is combustible having a calorific value of 4.5- Gasifier could be suitable for such applications, which the cut Biomass for consumption. þ Conservation of depleting fossil fuel 5.0 MJ/kg, with an average composition of CO : 20 + provides a better control of temperature with smokeless þ Conservation of Environment from 1%; CH : 3 + 1%, H : 20 + 1%, CO : 12 + 1% and rest, operation thereby enhancing the product quality. 4 2 2 APPLICATIONS Global warming & Pollution N . This process is made possible in a device called 2 Furnaces: In non-ferrous metallurgical and foundry þ gasifier. A gasifier system mainly comprises of a Encourage energy plantation thus industries high temperatures (~650 - 1000 0C) are Power Generation reactor, where the combustible gas is generated and the resulting in a green environment required for melting metals and alloys. Expensive fuel ! Captive power for industries gas is made available for power generation / thermal þ Provides a sustainable, affordable and oils or electrical heaters generally meet this. Gasifiers ! Grid connected for power sale application after the required cleaning and cooling eco-friendly alternative fuel are well suited for such applications. ! Village electrification process. þ Improvement of nations energy security Boilers: Gasifiers are well suited for any process Thermal using locally available fuels POWER GENERATION industries, which requires steam / hot water. ! Cooking in hotels, hostels, Marriage halls APPLICATION Apart from these, energy requirements in mass ! Replace high cost fuels like Diesel, LPG, Furnace Oil in cooking, poultry farms, cold storage devices (vapor industrial Boiler, Driers, Kilns, Furnaces, etc. Using producer gas, it is possible to operate a diesel compression refrigerator), rubber industry, textile ! engine on Dual Fuel Mode with marginal changes to the Vegetable drying, Fish drying, Paddy drying, etc. industries, chemical industries, sago factories and so air inlet or in a 100% Producer Gas Engine. In dual fuel on could be met using biomass gasifiers. Combined Cycle mode, diesel substitution of the order of 80 to 85% can be obtained at nominal loads. The recent developments Power generation and thermal application in industries. have made possible the operations of Spark ignited gas GOVERNMENT’S ASSISTANCE engine using producer gas alone. The mechanical To promote the non-conventional energy sources, energy thus derived can be used directly to energizing Government of assist the entrepreneur through mechanical device or by coupling with an alternator for attractive capital subsidy. *Central Financial Assistance power generation, either for local consumption or for (subsidy) of Rs. 10.00 lakhs per 100 kWe on pro-rata grid synchronization. m Generate your own power m Increase profit margin m No skilled man power required m Cost per unit Rs. 1.80 only m Eco friendly and easy to operate m Avail subsidy from MNES PROCESS FLOW DIAGRAM
