Advanced monitoring of industrial burners based on fluctuating flame signals

This paper presents and discusses measurements of local flame temperature, local gas species concentrations and incident wall heat fluxes obtained in a 250 MWe residual fuel-oil front fired utility boiler. The work is aimed at improving knowledge of the efficiency of the thermal processes involved in large industrial boilers and covers three different operating conditions, which include load and air-fuel ratio variations. The measurements were made using special design probes through the ports available for inspection of the boiler. Local gas temperatures varied between 1650°C in the centre of the flames attached to the burners to around 1100°C close to the boiler nose, with maximum variations in the plane of the burners between the front and rear walls of about 200°C. The levels of CO were as high as 2% close to the ash pit and reach 1% near the boiler nose, suggesting some limitations in the process of fuel burnout and CO oxidation. Wall incident total heat fluxes varied between 200 k W/m2 and ...

Temperature, Species and Heat Transfer Characteristics of A 250 MWe Utility Boiler

Combustion tests on an industrial glass-melting furnace

This article presents a proposal for an “Integrated cross-platform security assessment framework” (ICpSAF) for real-time security management, which is one of the results of the TecSEG Project (Security Technologies Project), a long-term Brazilian program focused on Research, Development and Innovation in Security Assessment. It is known that there are several frameworks related to security assessment, however, the vast majority have a specific focus on some technology, which is not a reality in the current scenario, where there is and is required a great heterogeneity of technologies in the solutions. To meet this challenge, the TecSEG project was proposed, where one of the main objectives is the development and application of security assessment and investigation methodologies with strong integration with national and international cybersecurity reference centers, which the framework proposed in this article is the base.

ICpSAF - Integrated Cross-platform Security Assessment Framework

Measurements of the incident wall heat fluxes and local flame temperatures and major species concentrations were obtained in a large industrial 250MWe utility boiler and are presented and discussed together with results obtained in a 350kW model swirling burner. The work is aimed to improve knowledge of the thermal processes involved in large-scale oil-fired combustion systems and quantify the extent to which combustion is limited by chemical kinetics, as well as the existence of zones characterized by temperature gradients or those with excess CO. The results in the model burner include the rate at which liquid droplets spread in a turbulent swirling flame and are of interest to improve knowledge of the mixing process of the fuel with air in practical burners.
