| 摘要 |
The invention relates to a fuel gas generator (401), for the generation of fuel gases by the gasification of organic or inorganic fuels in a reactor shaft (405), which comprises a descending flow gasification zone (427) and an ascending flow gasification zone (471), arranged beneath the above and, between the two gasification zones, a gas withdrawal unit. Both the downward flow gasification zone (427) and the upward flow gasification zone (471) are each divided into an oxidation zone (433, 475) and a reduction zone (435, 473), whereby the gasification agent introduction occurs in the oxidation zone (433, 475). Within the shaft reactor (405), void spaces are maintained by means of grating elements (423, 437, 480), with adjustable material throughflow, namely a descending flow gasification void space (434), which either borders on to the descending flow gasification oxidation zone (433), or is formed therein and through which the introduction of gasification agent to the descending gasification oxidation zone (433) occurs, or an ascending flow gasification void space (482) through which the gasification agent for the ascending flow oxidation zone (475) is introduced and a gas removal void space (469), formed between the descending flow gasification zone (427) and the ascending flow gasification zone (471). |
