Heatcrack substrate heat exchanger type WT-SWT
Product overview Heatcrack substrate heat exchanger type WT-SWT
Structure of the Heatcrack substrate heat exchanger type WT-SWT
Components of the WT-SWT
The WT-SWT consists of a tubular heat exchanger which is supplied with heat by the heating water of the combined heat and power station.
The WT-SWT is fed by a displacement pump which consistently pumps the substrate through the WT-SWT in numerous short pump cycles evenly over a period of 24 hours. The substrate remains in the WT-SWT for at least 35 minutes. When the substrate leaves the WT-SWT, it has a temperature of 75-80 °C which improves both the speed of digestion and the degree of digestion in the post-digester.
Due to the high substrate temperature upon entering the post-digester (receiving pit downstream of the WT-SWT), virtually no additional heating is needed to operate the digester.
The result: The gas yield is increased significantly with the same amount of substrate.
