The brewery’s thermal recovery system integrates multi-effect heat exchange equipment to achieve full-process heat energy circulation, which is of great significance for energy conservation, emission reduction, cost reduction, and efficiency improvement. The brewing process generates a large amount of waste heat. Taking wort boiling as an example, the steam is condensed by the brewing water when passing through the high-efficiency shell and tube heat exchanger. While achieving steam condensation, the 82°C hot water can also be recovered to the hot liquor tank for brewing, which can save about 7% of energy.
Key Features
The temperature of the condensed water produced by steam heating can reach 98~100℃. This condensed water is circulated back to the boiler water tank through the circulation pipeline, reducing the boiler load and saving energy consumption. Compared with direct discharge, it can save about 20% of heat energy waste.
Equipped with a frequency conversion-controlled centrifugal pump to ensure that the flow rate of 78℃ hot water between the thermal storage tank and the condenser is stable at 5-8m³/h and the pressure is maintained at 0.3-0.5MPa
The secondary steam (100-105℃) discharged from the brew kettle enters the tube condenser and performs countercurrent heat exchange with the 78℃ hot water at the bottom of the thermal storage tank. The steam condenses into 85℃ condensed water. At the same time, the hot water is heated to 97℃ and returned to the upper part of the thermal storage tank by gravity flow.
The energy storage tank adopts a high-diameter ratio design to improve thermal storage efficiency and avoid heat loss.
The thermal storage tank maintains stratification stability through a PID control system.
Configuration
Improved energy efficiency: Saving steam by optimizing thermal center operation.
