✦ Synopsis
Gasification of the biofuel or the waste material takes place in a fluidized bed gasifier, preferably a circulating fluidized bed gasifier. The gas produced in the gasifier is introduced into a boiler equipped with fossil fuel burners, typically burners for pulverized coal. The gas is introduced at a level above the burners. Ash from the boiler may be used to form the bed of the gasifier. For control of NO,, the gas is burned in the upper part of the boiler at EOO-105O"C, preferably 850-900°C and an excess air content of 5-10%. In a second embodiment, the raw gas may be cleaned of harmful or noxious components, and cooled if desired, between the gasifier and the boiler in an additional circulating fluidized bed reactor with a bed of coal ash.
