Parametric calculations reveal energy-efficient plasma gasification of municipal solid waste, suggesting improved waste treatment is essential for stability.
The development of the best technologies for waste disposal and neutralization, their implementation and improvement is an urgent task. One of the promising technologies based on thermal effects, namely high-temperature plasma gasification, is considered in this paper from the energy efficiency point of view. Among the wide variety of waste, the emphasis is placed on waste from the municipal sector and solid fuels produced from them. Based on parametric calculations, it is shown that due to the high degree of dispersion of waste characteristics, it is not possible to obtain a stable plasma gasification process with a positive energy balance without special waste treatment that stabilizes their characteristics. At the same time, when solid fuels from household waste of grades 1-3 (according to GOST 33516-2015 classification) are used as raw materials, the plasma gasification process will take place with positive energy efficiency parameters.
