300 tons/day of municipal solid waste incinerated for power generation

Core principle of incinerator combustion (mechanical grate incineration)

The grate is divided into three progressive sections: the drying section, the combustion section, and the complete combustion section.

Principle of waste heat recovery power generation (for a 3 MW generator set)

High-temperature flue gas from the secondary combustion chamber enters the waste heat boiler, where it flows through the boiler's water-cooled walls, superheater, and economizer, heating the softened water inside the boiler to produce high-temperature, high-pressure steam.

High-pressure steam is delivered to the steam turbine generator set, driving the turbine blades to rotate and thereby powering the generator to produce electrical energy.

A portion of the generated electricity is supplied for internal use by plant equipment (e.g., fans, pumps, central control systems, chemical dosing systems), while the remainder is fed into the grid for external distribution.

The low-temperature steam or condensate after the turbine has done work is returned to the waste heat boiler for cyclic heating, forming a closed water circulation system.

Domestic waste → thorough incineration at high temperature and dry conditions → high-temperature flue gas generates steam → the steam drives a 3 MW generator to produce electricity; dust, acidic gases, nitrogen oxides, and dioxins generated during incineration are purified through integrated flue gas treatment systems; leachate, odors, and ash residues are treated in a closed-loop system using dedicated equipment, achieving harmless disposal, volume reduction, and resource recovery of waste.
