Modeling Analysis and Research on the Evaporation System of a Multisource Organic Solid Waste Incinerator

Abstract

The co-incineration of multisource organic solid waste has gradually become an important method for solid waste recycling. Through a combination of computational fluid dynamics simulation and field monitoring, a distributed parameter model of the evaporative heating surface of an incinerator was developed. The distributions of heat flux, wall temperature, and steam quality in the incinerator were analyzed under four combustion conditions involving solid waste from various sources, types, and proportions. The results revealed that under the two working conditions with 20% waste cloth, as the calorific value of the mixed fuel increased, both the peak heat flux and the peak wall temperature increased, and the nonuniformity of heat transfer within the furnace intensified. Under the influence of the composition and calorific value of the mixed fuel, the steam quality of the working fluid at the outlet of the rear water wall in the cases with 20% waste cloth was significantly higher than that in the case of pure municipal solid waste combustion and the case with 20% sludge. This study offers valuable insights into the resource utilization of multisource organic solid waste in co-incinerators.

Impact of Integrating Flameless Combustion Technology and Sludge–Fly Ash Recirculation on PCDE Emissions in Hazardous Waste Thermal Treatment Systems

“…High temperatures in this stage cause low-boiling-point organic compounds to volatilize and react with oxygen, forming water vapor (H 2 O) and carbon dioxide (CO 2 ). This process can create localized areas with limited oxygen (hypoxic zones) and generate incomplete combustion products (PICs) [48,49].…”

“…Municipal solid waste incineration (MSWI) serves as a sustainable approach method for effectively managing the challenges posed by municipal solid waste (MSW) in terms of environmental sustainability [1]. Through high-temperature combustion, it transforms MSW into ash and heat energy, playing a pivotal role in tackling the escalating environmental issues associated with MSW treatment [2]. It also mitigates, to a certain extent, the negative impacts of conventional landfilling and composting practices on the environment.…”
