Feedstock unit consumption of biomass gasification power generation

Item No.	Feedstock	Feedstock consumption per kwh (KG)	Unit
1	Rice husk	1.6 - 1.8	Kg/kWh
2	Crop stalk	1.5 - 1.8	Kg/kWh
3	straw	1.6 - 1.7	Kg/kWh
4	Saw dust	1.1 - 1.3	Kg/kWh
5	Wood chip	1.3 - 1.5	Kg/kWh
6	Coconut fiber dust	1.6 - 2.0	Kg/kWh
7	Palm bunch	1.7 - 1.9	Kg/kWh

Notes:

1. Consumption fluctuates with each biomass feedstock, and moisture after drying,
2. The above data is for fluid bed gasifying furnace. For fixed bed gasifying furnace, the feedstock consumption will be higher than this.
3. The above data is got basing on the engine we mentioned on the above, if customer use another manufacturer’s engine, the data will fluctuate.

It is more useful for seasonal units as they can manage without taking Electric Connection from the state electricity Board and save the minimum & fixed charges, which they have to pay when the unit is not running.

The Operation and Maintenance of Bio Mass Gasifier Plant is so simple and standardized that existing technicians/laborers can be trained during installation/commissioning of the plant.

The Annual Maintenance Cost of Biomass Gasifier is <3% of Plant cost and AMC will take care of preventive, periodical and break down maintenance by the manufacturer.

NOC is not required from any Government Agency for setting up Biomass Gasifier as it is a Green, Clean and Renewable Energy. This comes under Government Promotional scheme and the Government extends a lot of benefits like:

          1. Accelerated Depreciation of 80%
          2. IT exemption for 9 years
          3. Central Grant of Rs.1.5 Crores/MW
          4. Carbon Credits.

Bio Mass Gasifier plants can be put to different sizes depending on the captive requirement and the local availability of biomass – 500 kw to 6MWe. Each Kw also produces twice the amount of heat which can be harnessed for Heating/Drying and Chilling/Air-conditioning.

Biomass Gasifiers does not cause any pollution. It is Eco-friendly and reduces the Green House Gas emission, Acid rain etc and is eligible for CDM benefits under Clean Development mechanism (CDM).

Producer Gas from Biomass Gasifier system can be used directly in the Diesel Engine. Generally, in these dual fuel Diesel Engines; 15-35% of Diesel and the balance 85%-65% Producer gas is used. No modification is required in the Engine for operation in Dual fuel mode.

A Bio Mass Gasifer Plant can be set up in 6 months time.

This is a relatively proven technology which has been perfected in a very short time-span considering the importance of Clean and Green Energy from renewable fuel sources at a low cost suitable for the Agrarian Indian conditions. The increase in price of fossil fuel (Diesel, FO, LDO, Coal), erratic Power Supply and the need for economical uninterrupted power supply, Bio Mass Gasifier is gaining popularity as a low cost renewable option with versatile applications as Power Generation and thermal application.

With large land bank available for cultivation, backward integration to tie-up for Bio mass cultivation is also possible. Hybrid variety of trees are now available which can be cut in 2 years and sustained for regular cutting every year thereafter to offer continuous bio-mass supply at viable prices. This cultivation by itself is an independent revenue generating model. 300 Acres of land is sufficient to sustain a 2 MW plant from the second year of plantation and we recommend that this be considered as an integrated project.
