Rice husk in its loose form (Fig. 2) is mostly used for energy production, such as combustion and gasificationbustion is the process of burning carbon in the rice husk, which emits CO 2 and generates heat energy for further use. One of the most efficient uses of this by-product is its direct combustion without the need for a heat exchanger with a proper furnace to generate heat for …

grinding process. To ensure the product is dried evenly, the raw material is con-veyed pneumatically through a stream of hot gases and dried in a convective pro-cess until it reaches a residual moisture content of approximately 10–12%. FINE-GRINDING By finely grinding the raw materials in the 43" fine grinding hammer mill it is

Handbook of Biomass Downdraft Gasifier Engine Systems Gasification Biomass can also be directly converted to energy through gasification. During the gasification process, a biomass feedstock (usually MSW) is heated to more than 700° C (1,300° F) with a controlled amount of oxygen. The molecules break down, and produce syngas and slag.

This Biomass Handbook deals with the characteristics and resources of biomass, thermochemical and biochemical conversion of biomass, and system development of sustainability. However, the most important aspect is the contribution of many specialists of

III THEORY OF GASIFICATION The production of generator gas (producer gas) called gasification, is partial combustion of solid fuel (biomass) and takes place at temperatures of about 10000C. The reactor is called a gasifier. The combustion products from complete combustion of biomass generally contain nitrogen,

the biomass does not directly contact the water and the vertical design allows any water that condensed on the biomass to drain back into the boiling flask. Steam distillation of biomass generally yields two products: a relatively high purity essential oil and an aqueous condensate called a hydrosol. The oil consists of

WOODY BIOMASS Overview Use of woody biomass such as mill residues and forest residues is not a new practice by any stretch of the imagination. There is a long and widespread tradition of the use of woody biomass in energy appli-cations such as a boiler fuel, and it represents a very large fraction of the total renewable energy produced
