AI Technical Summary

Technical Problem

The flexibility of retrofitting existing thermal power units is limited by the limited depth of boiler peak shaving, resulting in insufficient economic efficiency and safety of the units. Frequent adjustments reduce their service life, and operation at low load rates leads to reduced safety, economy, and environmental protection, as well as lower returns.

Method used

The power plant peak-shaving system, including boilers, steam turbines, flue gas treatment equipment and solid waste reaction equipment, is adopted. The solid waste grinding unit is driven by the steam generated by the boiler and/or steam turbine to grind the solid waste into powder, and then mixes and reacts with the flue gas in the flue gas reactor to generate economically valuable by-products, while achieving partial removal of CO2.

Benefits of technology

It fulfills the power plant's deep peak-shaving needs, improves economic efficiency and environmental protection, meets dispatch and peak-shaving requirements, and the generated by-products can be used in the construction industry to obtain carbon emission reduction benefits.

Abstract

This invention relates to a power plant peak-shaving system and method. The power plant peak-shaving system includes: power generation equipment, flue gas treatment equipment, and solid waste reaction equipment. The power generation equipment includes a boiler and a steam turbine, with the boiler connected to the steam turbine. The flue gas treatment equipment is connected to the boiler and is used to treat the flue gas discharged from the boiler. The solid waste reaction equipment includes a solid waste grinding unit and a flue gas reactor. Both the boiler and the steam turbine are connected to the solid waste grinding unit. During power plant peak shaving, the steam generated by the boiler and / or the steam turbine drives the solid waste grinding unit to grind the solid waste into powder. The flue gas reactor is connected to the solid waste grinding unit and the flue gas treatment equipment, and is used to mix and react the powder and the flue gas to form a finished product. The power plant peak-shaving system of this invention can flexibly shave peaks, has high economic efficiency, and good environmental protection effects.
