Gasifiers are classified mainly on the basis of their gas–solid contacting mode and gasifying medium. Based on the gas–solid contacting mode, gasifiers are broadly divided into three principal types (Table 6.1): (1) fixed or moving bed, (2) fluidized bed, and (3) entrained flow.Each is further subdivided into specific types as shown in Figure 6.1.
reactor and the Gibbs reactor are utilized as gasifiers to study the composition and the heating value of the produced gas. The aim is to develop a model, which gives a good approximation to the gasification reactor. Table 1. Reaction kinetics for the major conversion rates in a gasifier reactor (Xie et al., 2013 and Umeki et al.,2010).

The reactor is called a gasifier. The combustion products from complete combustion of biomass generally contain nitrogen, water vapor, carbon dioxide and surplus of oxygen. However in gasification where there is a surplus of solid fuel (incomplete combustion) the products of combustion are (Figure 1)

Types of Gasifiers Although there are various types of gasifers (gasification reactors), different in design and operational characteristics, there are three main gasifier classifications into which most of the commercially available gasifiers fall. These categories are as follows: Fixed-bed gasifiers (also referred as moving-bed gasifiers)

The correlation between thermochemical provenance and biochar functionality is poorly understood. To this end, operational reactor temperatures (spanning the reduction zone), pressure and product gas composition measurements were obtained from a downdraft gasifier and compared against elemental composition, surface morphology and polyaromatic hydrocarbon content (PAH) of the char …

Gasifier Type Downdraft Gasifier A downdraft gasifier is a co-current reactor where air enters the gasifier at a certain height below the top. The product gas flows downward (giving the name downdraft) and leaves through a bed of hot ash. Since it passes through the high-temperature zone of hot ash, the tar in the product gas fnds favorable ...
Updraft Gasification. Updraft (also counter-current) fixed bed gasification is a thermochemical conversion process that produces a synthesis gas, or "syngas"; this product gas can consist of a substantial amount of useful energy depending on the higher heating value of the fuel being used.
