Combustion Of Heavy Fuels And Liquid Wastes
This paper describes the design and operating conditions of liquid and gas combustors for heavy fuels and liquid wastes. Lower fuel prices can be achieved by switching from light oil to heavy ones, or combining with unconventional waste fuels. Unconventional waste fuels such as energetic off gases and organic liquid waste require especially designed combustion equipment like a special combustor ...

A method to extend flamelet manifolds for prediction of NOx and long time scale species with tabulated chemistry
Numerical simulation is currently used to help design low NOx devices for aircraft engines. In order to improve the prediction of pollutant species, combustion models based on tabulated chemistry have been commonly used in recent years. However, the short time scales of usual flamelet manifolds can lead to errors concerning the NO prediction in post flame area, as shown in this paper. Thus, a new ...

NOx re-burn simulation in a double-jet counter-flow flame
The paper investigates the main features of NOx emission in a laminar double-jet counter-flow diffusion flame for later use as a possible physical model for NOx reduction through turbine in situ reheat. The oxidizer stream consists of exhaust gas resulted from a conventional combustor and the fuel stream is represented by an air?methane mixture. The main interest rests on the distribution of NOx ...

Sample conditioning issues emissions monitoring from combustion processes
ABSTRACT Preventing condensation within gas samples is important if accurate measurement of a soluble component is required - principally nitrogen dioxide within combustion products. Maintaining gas samples above the water or acid dew point is normally achieved by heating the sample transfer lines and gas analyser modules. This paper presents simple methods for the dew point calculation of ...

Carbon Injection Proves Effective In Removing Dioxins
Untitled Document Summary: During the past several years, there has been growing concern about emission of polychlorinated di-benzo-p-dioxins and polychlorinated di-benzofurans (PCDDs/PCDFs). Dioxins and related compounds are byproducts of combustion formed by recombining other organic constituents and chemical reactions in the combustion effluent-gas stream. ...

Phosphorus from Sewage Sludge Ashes - Case Study
Phosphorus recovery from phosphorus-rich asses of SNB and HVC Sewage water in the Netherlands contains approximately 12 million kg of phosphorus of which 85% ends up in sewage sludge. When sewage sludge is burned in a mono-sludge combustor, such as at HVC and SNB, most of the phosphorus ends up in the fly ash. Fly ash contains up to 27% phosphorus. EcoPhos, in cooperation with SNB and HVC, ...

`A Case Study in Implementation of the NESHAPs for the Portland Cement Industry at a Major Source,` appeared in Cement Americas magazine, July/August 2003
Introduction Located at 40 CFR 63, Subpart LLL, the Portland Cement (PC) MACT standard poses a significant regulatory hurdle to the cement industry-Facilities subject to its requirements had to complete initial performance testing and develop their first substantial semi-annual monitoring report by January 31, 2003. The final Portland Cement MACT rule was promulgated on June 14, 1999, and ...

X-Ray Fluorescence-Based Multi-Metal Continuous Emission Monitor
ABSTRACT: Army demilitarization incinerators will need to comply with the Hazardous Waste Combustor National Emission Standard for Hazardous Air Pollutants that will regulate metals and metal compounds listed under the Clean Air Act Amendments. A large problem for these incinerator operations is limited knowledge of the type and quantity of emitted metals, so that compliance may be determined ...

Gaseous emissions during concurrent combustion of biomass and non-recyclable municipal solid waste
Abstract Background: Biomass and municipal solid waste offer sustainable sources of energy; for example to meet heat and electricity demand in the form of combined cooling, heat and power. Combustion of biomass has a lesser impact than solid fossil fuels (e.g. coal) upon gas pollutant emissions, whilst energy recovery from municipal solid waste is a beneficial component of an integrated, ...
