METHOD AND GAS GENERATOR FOR GASIFICATION OF A SOLID FUEL WITH THE LOW CALORIFIC VALUE, PARTICULARLY OF A BIOMASS WITH THE WIDE SPECTRUM OF HUMIDITY

摘要

The method and the gas generator for gasification of the solid fuel with the low calorific value, particularly of the biomass with the wide spectrum of humidity is characterized in this that there is made prior assessment of fuel reactivity and humidity using the known methods and then fuel is introduced through the top inlet into the gasification chamber (1) which is located inside of the external chamber (3) in an inside of which there is axially built-in the slot grate (4) in the form of a truncated cone of the angle (a) of an inclination of the wall in relation to the plane ranging from 20° to 80° and the lower part of the external chamber (3) constitutes the air box (7). Under the grate (4) there is located the chamber of ash receiving (5). Moreover, gasifying medium nozzles (8) are located on the surface of the pipe wall of the pyrolysis chamber on the height (h2) from the lower edge of the slot grate (4).
