200t/d-300t/d Complete waste incineration system
The incineration system consists of a feeder, a grate, an ash hopper, an ash conveyor and a slag remover, and is suitable for domestic waste incineration projects with a daily throughput of 30~600 tons.
Main equipment
Hopper and feeder
The feeding system consists of a hopper and a feeder; a gate is provided inside the hopper, and while ensuring sealing, the gate also serves the bridge-breaking function; when waste arches and blocks in the hopper, the bridge is broken through the action of the gate. The feeder and the gate are driven by oil cylinders and push a certain amount of waste into the incinerator through periodic reciprocating push-and-pull movements, and the feeder can adjust the feeding speed according to the incinerator load.
Stepped grate
The grate of the municipal solid waste (MSW) incinerator is a downward-pushing stepped inclined reciprocating grate; the grate is divided into three stages of drying, combustion and burnout, and a height difference is set between each grate section, so that the waste is loosened when falling and is pushed to move forward, while the waste is prevented from gathering together and causing incomplete combustion. The stepped grate is driven by hydraulic cylinders, the three grate sections can be controlled independently, and the movement cycle of the grate can be adjusted according to the combustion state in the furnace.
The grate is made of heat-resistant cast steel and has good wear resistance, high-temperature resistance and corrosion resistance.
Ash conveyor and slag remover
The ash removal system consists of the ash hopper under the furnace (which also serves as the air chamber), the horizontal ash conveyor and the slag remover. A small amount of fine ash produced after the waste is completely burned falls through the grate gaps into the ash hopper and then gathers into the horizontal ash conveyor. The main ash and slag produced by waste combustion are pushed into the slag hopper by the combustion-stage grate and then enter the wet slag remover together with the fine ash. All ash and slag are sent into the slag pit by the slag remover.
Process features
- Simple structure, convenient operation and maintenance;
- The grate is resistant to high temperature, corrosion and wear, with a low replacement rate;
- Uniform air distribution of the grate, uniform waste combustion;
- Full waste incineration, with a thermal ignition loss rate ≤5%;
- Modular equipment, convenient installation and short construction period;
- Fully automated equipment.

Application solutions
50t/d
Process flow：①Waste into furnace → incineration → cooling → flue gas treatment → compliant emission ②Waste into furnace → incineration → waste heat boiler → flue gas treatment → compliant emission
Basic parameters：Daily throughput: 50t Saturated steam output: 3~5t/h
Scope of application：Projects with a daily throughput of 50t are suitable for the harmless and volume-reducing treatment of domestic waste in small areas such as townships. According to the project situation, the high-temperature flue gas can be directly cooled and purified before discharge, or a 3~5t/h saturated steam boiler can be equipped to produce and sell steam. It is not suitable for power generation. The project scale is small; on the premise of meeting the same environmental standards, the investment per ton of waste is too high, the project has no profit point, and it is not economically feasible. It is suitable for non-profit demonstration projects or scenarios with reliable steam users, so as to increase a certain output value. In this solution, the incinerator and the waste heat boiler are arranged separately in a horizontal layout and connected by a high-temperature flue duct. Compared with traditional large-scale waste incineration projects, the overall height of the equipment in this solution is significantly reduced, and the total equipment height is below 20m.
100~200t/d
Process flow：Waste into furnace → incineration → waste heat boiler → flue gas treatment → compliant emission
Basic parameters：Daily throughput: 100200t Saturated steam output: 820t/h
Scope of application：Projects with a daily throughput of 100t are suitable for the harmless, resource-recovering and volume-reducing treatment of domestic waste in small areas such as townships, as well as waste heat recovery and utilization, and are equipped with an 8~10t/h saturated steam boiler. The scale is rather small and unstable, so it is not suitable for power generation. However, the steam output is considerable and needs to be sold externally for profit or used in combination with other industries that need steam. The incinerator and the waste heat boiler are arranged separately in a horizontal layout.
200~300t/d
Process flow：Waste into furnace → incineration → waste heat boiler → flue gas treatment → compliant emission, with the steam used for power generation
Basic parameters：Daily throughput: 200300t Superheated steam output: 1630t/h Annual power generation: 3200~4800 ten-thousand kWh
Scope of application：Projects with a daily throughput of 200300t are suitable for the harmless treatment and waste heat recovery of domestic waste at county level, and are equipped with a 2030t/h superheated steam boiler + 4~6MW turbine generator unit.
Project cases
600t/d waste incineration power generation project in Ho Chi Minh City, Vietnam (large-scale waste incineration power generation project)
The 600t/d waste incineration power generation project in Ho Chi Minh City, Vietnam adopts our three-stage inclined reciprocating grate incinerator, with a daily waste throughput of 600t, and is equipped with a 75t/h steam boiler + 18MW generator unit. The project is currently under construction and is planned to be put into operation in December 2024.
