AI Technical Summary
In existing technologies, combined heat and power (CHP) units suffer from energy waste due to steam pressure differential during the steam supply process, resulting in a prominent contradiction between steam supply and peak shaving. Individual steam differential pressure recovery devices and molten salt thermal storage systems cannot effectively resolve the contradiction between peak and valley steam supply and peak shaving, leading to low energy utilization and limited peak shaving capacity.
By constructing a deep-regulation steam supply system that couples steam differential pressure recovery with molten salt thermal storage, including a steam differential pressure recovery module, a molten salt thermal storage module, a steam supply regulation module, an electrical energy processing module, and a central control module, the steam pressure difference energy is converted into electrical energy. Molten salt is used as an intermediate energy storage medium, and a heat path is constructed by combining the steam supply main pipe and the molten salt thermal storage module to achieve cascaded utilization of energy and peak shaving and valley filling of steam supply load.
It has achieved effective recovery and storage of steam pressure difference energy, resolved the contradiction between steam supply and peak shaving, improved energy utilization, ensured steam supply stability and peak shaving capacity, and reduced operating costs and the impact of equipment failure.
