MSW gasification power plant
Overview
The waste gasification power plant is based on the characteristics of waste(MSW,Industrial waste, sludge, medical waste), and realizes a two-stage treatment process for the first gasification of the waste and subsequent oxygen-enriched combustion, so that the waste is completely burned.The generated high-temperature flue gas heats the waste heat boiler and generates steam to drive the steam turbine/screw expansion generator to generate electricity. After the exhaust gas is purified by a deacidification tower, activated carbon, and a dust collector, meet the standard to discharge. (Suitable for small and medium waste disposal)
Raw Material Required: Moisture≤15% Size : 3-10cm
Product feature
- 1
The two-stage treatment process of waste pyrolysis gasification and oxygen-enriched combustion makes the waste completely combusted, and the residual heat reduction rate and leaching toxicity after treatment are lower than the Euro standard.
- 2
Pyrolysis and gasification process is carried out under anaerobic condition, which reduces the generation of dioxin precursors.
- 3
The temperature in the second combustion chamber is up to 1000℃, and the flue gas residence time is more than 2s, can rapidly decompose dioxin-like substances, in this way, the content of heavy metals, dioxins and other harmful substances in the fly ash discharged by waste disposal can be reduced, and the secondary pollution to the environment can be greatly reduced.
- 4
The unique structural design of Haiqi waste pyrolysis gasifier overcomes the two major technical problems of uneven fuel distribution and slag continuous discharging problem by the rotation of the rotary fule distributor and grate. It maintains the relative stability of the operation condition, makes the process of feeding and discharging controllable, and the operation and maintenance of starting and stopping furnace is convenient.
- 5
Pyrolysis gasifier has strong adaptability and wide application range. It can not only deal with garbage with high calorific value, but also deal with garbage with low calorific value.It can be applied to the disposal of municipal solid waste, industrial waste, agricultural and forestry waste.
- 6
The design of pyrolysis gasifier is scientific and reasonable, simple and compact in structure, easy to realize automatic control, light in weight, easy to arrange and short in construction period.
- 7
The system has low energy consumption and cost, less land, low investment and obvious economic benefit.
- 8
The unique temperature field distribution of pyrolysis gasifier not only does not need to add auxiliary fuel, which is conducive to the pyrolysis and gasification of waste, but also makes the thermal efficiency higher and the thermal burning reduction rate lower.Working in the low temperature area, the furnace grate avoids the heat effect of high temperature on the furnace grate, reduces the equipment manufacturing cost, improves the reliability of equipment operation, and prolongs the service life of the equipment.
- 9
Waste materials can be simply sorted and then can be put into the pyrolysis gasifier.
- 10
Waste heat from waste disposal can be fully utilized.
- 11
Internal combustion engine, steam turbine and screw expansion generator can be used to generate electricity, which can not only meet the self-use of the plant, but also provide power/heat to the nearby communities, and become part of the national distributed renewable energy.
Application scope
Use all kinds of Agricultural and forestry waste to generate electricity, supply to factory or connect with national grid.
