Description

Technical Field

[0001] The utility model relates to the technical field of boiler waste water heat utilization, in particular to a recovery mechanism for efficiently recovering waste water heat in a boiler. Background Art

[0002] Boiler waste water heat utilization is an energy-saving and environmentally friendly technology, which involves recovering and reusing the waste water heat in the waste heat generated during boiler operation. This waste water heat usually comes from the waste water and steam condensate discharged from the boiler, which contains a large amount of thermal energy.

[0003] When using boiler waste water heat utilization technology to heat the boiler's added water, if the technology cannot fully heat the boiler's added water, this will directly lead to a decrease in the heating efficiency of the boiler's added water. The reduction in heating efficiency not only means that it takes longer to preheat or reach the required temperature, but also increases the boiler's energy consumption during the heating process. Therefore, optimizing the boiler waste water heat utilization technology and ensuring that it can effectively convert waste heat into thermal energy for heating the boiler's added water is an important measure to improve boiler energy efficiency and reduce energy consumption. By improving this technology, we can use energy more effectively, reduce unnecessary energy waste, and provide strong support for the energy-saving operation of the boiler.
