AI Technical Summary
Existing reciprocating grate incinerators have complex structures, high investment costs, high maintenance rates, and cause waste to accumulate in clumps, resulting in uneven heating, low thermal efficiency, and making it difficult to improve the thermal efficiency of waste incineration systems and the amount of electricity generated per ton of waste.
The system adopts a combination of fixed grate and movable grate structure. The movable grate assembly reciprocates on the fixed grate. Combined with the air blowing hole design and water cooling pipes, it achieves the turning and uniform combustion of waste. By setting air blowing holes and water cooling pipes on the fixed grate, it ensures that the waste is turned and fully combusted.
It achieves high efficiency, simple structure, low cost, large waste processing capacity, high combustion efficiency, and low system maintenance cost of waste-to-gas incineration system, significantly improving the thermal efficiency and power generation per ton of waste.
