US9410095B2 - Method of gasification of biomass using

A wood gasification boiler. Wood is burned in the firebox (top), and gases travel downward and are burned at 1,800 to 2,000 F in the ceramic chamber below. The hot gases then pass through a fire-tube heat exchanger to transfer heat to water stored in a large tank. Flue temperatures are usually under 350 F, and there is no creosote.

What is Gasification?

Gasification is a process to convert carbonaceous material into gas by using a gasifying agent. If this thermochemical process is performed in a conventional one-stage biomass gasifier, several process steps are overlapped, such as heating and drying of the fed biomass, pyrolysis of the volatiles, oxidation and gasification of the charcoal.

During combustion, fly ash, bottom ash, and boiler slag are produced. Fly ash produced from the burning of coal has become a generic term for all types of coal combustion byproducts. Specifically, fly ash is that portion of the ash stream composed of particles small enough (0.001 to 0.1 mm) to be carried from the boiler in the flue gas.
