Cascade steam utilization on the power generation and heat supply side
Combined heat and power (CHP) boasts advantages such as high energy utilization efficiency and minimal environmental impact. In recent years, it has become one of the key approaches for the clean utilization of coal. The National Development and Reform Commission’s “Action Plan for Upgrading and Transforming Coal-fired Power Plants to Enhance Energy Conservation and Emission Reduction (2014–2020)” encourages the development of CHP technologies tailored to local conditions and promotes the retrofitting of condensing steam turbines for heat supply.
- Under the strategic need to prevent and control smog: A large number of small coal-fired boilers with capacities below 30 steam tons that were used for self-supply have been forcibly phased out. It has become common practice for industrial steam users to meet their demand by drawing steam from pure-condensing units instead.
However, this has been accompanied by an increasingly prominent issue: the mismatch between industrial heat demand and the steam supply from power plants.
The steam turbines at power plants, originally designed primarily for power generation, can no longer adapt to fluctuations in regional heat and electricity demand, leading to significant waste of high-quality energy. Therefore, heating retrofit projects are being carried out on steam turbine units at large- and medium-sized coal-fired power plants.
Propose and implement an innovative solution to address the challenges faced in the heating retrofit of pure-condensing units.
Utilizing steam in a staged manner on the steam side.
The Ministry of Industry and Information Technology, the National Development and Reform Commission, and five other departments jointly issued the "Implementation Plan for Promoting Equipment Upgrades in the Industrial Sector," which calls for accelerating the green transformation of production equipment in the industrial sector and promoting efficiency upgrades of key energy-consuming equipment. To enhance enterprises’ overall energy efficiency and help them carry out precise equipment upgrades and energy conservation and carbon reduction efforts, steam system upgrades have become imperative.
During the production and operation of enterprises, reducing temperature and pressure consumes a large amount of steam energy.
Traditional equipment does not take into account the recycling of waste heat; after only undergoing temperature and pressure reduction, the steam is directly supplied to the workshop, resulting in low overall steam utilization and significant waste of energy resources.
By upgrading the steam temperature and pressure reduction system within the plant area and installing a cascade steam pressure differential power generation system, surplus steam will be converted into electricity, enabling the enterprise to generate and use its own power, thereby reducing energy costs.
Carry out steam pressure differential power generation retrofit on the steam temperature and pressure reduction devices used by steam-consuming units.
An innovative pressure-difference power generation solution is proposed for the energy-saving retrofit of steam temperature and pressure reduction stations.
