Type 1. Heat for carbonisation is generated by allowing part of the wood charged to burn to provide the heat to carbonise the remainder. The rate of burning is controlled by the amount of air admitted to the kiln, pit, mound or retort. This is the traditional system used to produce most of the world's charcoal.

Torrefaction removes moisture and volatiles from biomass, leaving biocoal. Torrefaction of biomass,, wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a relatively dry product, which reduces or eliminates ...

History The production of wood charcoal in locations where there is an abundance of wood dates back to ancient times. It generally begins with piling billets of wood on their ends to form a conical pile. Openings are left at the bottom to admit air, with a central shaft serving as a flue. The whole pile is covered with turf or moistened clay.

Planing: Smoothing the surface of each lumber piece and making its width and thickness uniform. Grading: The process of assessing the characteristics of each lumber piece in order to assign its "grade" (quality). The success of wood manufacturing rests on the mill's ability to retain the wood's quality throughout the manufacturing process.

The manufacturing process for "synthetic fuel gases" (also known as "manufactured fuel gas", "manufactured gas" or simply "gas") typically consisted of the gasification of combustible materials, usually coal, but also wood and oil. The coal was gasified by heating the coal in enclosed ovens with an oxygenpoor atmosphere.

Option 1. For the raw materials of charcoal briquette manufacturing process, you can use the finished biomass briquettes directly. Also you can use the organic wastes, and remember to dry them firstly. Put the collected biomass briquette or prepared organic wastes into the kiln, and control the combustion temperature and time.

The Direct Method. This is perhaps the easiest way to make charcoal. The direct method is to make a fire in a container, then add wood to it. Once it is burning, you cover the container loosely with a metal sheet to restrict the air. Watch as white smoke and steam from the wood comes out of the gaps around the cover.
