Techno-Economic Evaluation of Co-Removal of NOx and SOx Species from Flue Gases via Enhanced Oxidation of NO by ClO2-Case Studies of Implementation at a Pulp and Paper Mill, Waste-to-Heat Plant and a Cruise Ship

Jakob Johansson et al.

Summary: Co-absorption of NO2 and SO2, combined with enhanced oxidation of NO by ClO2(g), can achieve efficient removal of NOx and SO2 from flue gases. There are significant cost differences in treating different flue gas sources, and the selection of chemical additives plays a vital role in the economic feasibility of the technology.

Numerical Simulation of Combustion and Characteristics of Fly Ash and Slag in a V-type Waste Incinerator

Zixue Luo et al.

Summary: This study focuses on a V-type waste incinerator for municipal solid waste (MSW) combustion, utilizing computational fluid dynamics (CFD) methods to analyze the combustion process. The analysis of fly ash and slag characteristics reveals that their main constituents are CaO and SiO2, along with heavy metal elements such as Cu, Pb, and Cr. The error between CFD simulation data and measured data is less than 10%, demonstrating the accuracy of the modeling of the combustion process.
