Abstract
The apparatus for producing a product gas from a fine-grained carbon-bearing substance during a high-pressure gasification comprises a vertical gasifier and radiative cooling device, a vertical convective cooling device through which a flow occurs from top to bottom and a connecting pipe between a head of the gasifier and radiative cooling device and a head of the convective cooling device. The gasifier and radiative cooling device comprises a pipe-like shaft, a lower cinder outlet and an upper conical connecting piece for the connecting pipe. The shaft is constructed as an equal speed flow duct, which is not equipped for feeding a foreign cooling means, but is designed so that solidification of the accompanying cinders travelling with the product gas occurs by radiative cooling.
