The term 'updraft gasifier' may be new to common people. In fact, its a technical term which holds special 'know-how' for those who wants to dig the word 'gasification technology'.

Let's learn, what exactly is updraft gasifier and the technology behind this technical term.

In updraft gasifiers, gas is drawn out of the gasifier from the top of the fuel bed while the gasification reactions take place near the bottom. As the producer gas passes through the fuel bed, it picks-up volatile matter (tars) and moisture from the fuel. Therefore, the gas from the updraft gasifier contains condensable volatile. The design and operation of the gasifiers is such that the gas comes out at 450-500°C temperature.

At the above mentioned temperature, most of the volatile hydrocarbons are in vapor form, which add to the energy content of the gas. It is most appropriate to utilize updraft gasifiers in close-coupled-hot gas mode for direct heating applications. However, if the application warrants, the scrubbing of gas to remove the volatiles/ tars is also carried out.
