Infinite Gasification PlantThe Gasifier unit is essentially a chemical reactor, where several thermo-chemical processes such as pyrolysis, combustion, and reduction take place.
Most biomass materials like Wood , Charcoal , Rice Husk etc can be converted into a gaseous fuel known as producer gas, which comprises carbon monoxide, hydrogen, carbon dioxide, methane, and nitrogen. This gas has a lower calorific value (1000 - 1200 kcal/nm3) compared to natural gas or liquefied petroleum gas, but can be burnt directly with high efficiency and good degree of control without emitting smoke. The producer gas flame temperature can be as high as 1100 oC. Each kilogram of air-dry biomass (10% moisture content) yields about 2.5 nm3 of producer gas. In energy terms, the conversion efficiency of the gasification process is in the range of 80% - 90%.
Downdraft GasifierIn this type, air is introduced into downward flowing packed bed or solid fuels and gas is drawn off at the bottom. A lower overall efficiency and difficulties in handling higher moisture is the limitations in downdraft gas producers. The time (5-10 minutes) needed to ignite and bring plant to working temperature with good gas quality is shorter than updraft gas producer.
This gasifier is suitable for internal combustion engines after appropriate cleaning.
These gasifiers are best suited for applications where clean fuel gas is required and where temperature control is critical. These gasifier can be used in applications requiring moderate temperatures upto 600 Deg C. Typical applications where the Down draft gasifiers have been successfully used are:
- Continuous Baking ovens ( Bread, Biscuits, Paint)
- Batch type baking oven – rotary oven for bread
- Dryers & Curing – tea, coffee, mosquito coil, paper drying
- Thermic fluid heaters
- Annealing furnaces
- Direct fired rotary kilns
- Internal combustion Engines
Updraft GasifierAn updraft gasifier has clearly defined zones for partial combustion, reduction, and pyrolysis. Air is introduced at the bottom and act as countercurrent to fuel flow. The gas is drawn at higher location. The updraft gasifier achieves the highest efficiecy as the hot gas passes through fuel bed and leaves the gasifier at low temperature. The sensible heat given by gas is used to preheat and dry fuel.
These gasifiers are best suited for applications where moderate amounts of dust in the fuel gas is acceptable and a higher flame temperature is required. Typical applications where the updraft gasifiers have been successfully used are:
- Packaged Boilers
- Thermic Fluid heaters
- All kinds of Fryers
- Rotary type roasters
- Aluminium Melting /Annealing Furnaces
Universal GasifiersThese gasifiers are based on entrained-flow principle and have the ability to convert a practically any biomass into high quality producer gas with negligible tars. The only limitation in this gasifier is the fuel size, which is to be limited to <2 mm. The universal gasifier is unique in its ability to gasify even poor fuels like soya Husk, Mustard stalk, etc that contain high ash and have poor flow properties
The technology with its unique reactor design and the efficient dry-feeding system is based on more than 15 years of continuous product development.
