| 摘要 |
<p>The invention relates to a combined combustion and exhaust gas filter plant basing on a pressurized combustion in a combustion chamber (5), exhaust gas cooling and expansion in an expansion machine (14, 20) in a single or several steps with decreasing temperature for condensing at least the main parts of the contaminants to be collected in a separating means (22) at the outlet of the expansion machine (20). For completely or partly eliminating nitrogen oxides at the outlet and for the process there is a device connected to the combustion chamber for the supply of combustion air enriched with up to 100 % oxygen gas and a vacuum pump (27) is connected to the separating means (22).</p> |
