| | PDF (400 KB)

This paper is concerned with the use of neural networks as a means to represent the formation of pollutant emissions, resulting from the combustion of coal with a 1 MWth chain grate stoker test facility located at CRE Group Ltd. (CRE), Stoke Orchard, Cheltenham. The resultant black-box' models of the pollutant emissions, namely the nitrogen oxides and carbon monoxide emissions, were ab... View full abstract»

• ### Advanced monitoring and characterisation of combustion flames

Publication Year: 2000, Page(s):3/1 - 3/4
| | PDF (348 KB)

This paper describes the advanced monitoring and characterisation of a gaseous flame in a 10 MWth utility boiler using a recently developed instrumentation system. The physical properties of the flame are characterised in terms of a set of geometrical and luminous parameters, which are derived from the digital images of the flame. Results obtained have demonstrated that the system is ca... View full abstract»

The phenomenon of the noise given off by burners and flames has been the subject of much study. However all of these studies have concentrated on laboratory scale experiments and thus while noting complex relationships between temperature, noise and pressure signals these results have not been replicated on an operational system. This paper will examine an attempt to look at the noise and pressure... View full abstract»

• ### The possibilities for high temperature electronics in combustion monitoring

Publication Year: 2000, Page(s):9/1 - 9/3

| | PDF (352 KB)

High temperature electronics will increasingly penetrate the market for combustion monitoring and control; particularly where distributed systems and/or improved performance are required. HTE will enable sensors with increased functionality to be placed nearer to the actual point of combustion, which in turn will allow improved combustion efficiency. HITEN is a network of excellence in high temper... View full abstract»

• ### Analysis methodology of diesel spray and flame by means of in-cylinder endoscopic imaging

Publication Year: 2000, Page(s):13/1 - 13/4

| | PDF (508 KB)

In-cylinder endoscopic imaging has been presented as an optical diagnostic tool for diesel spray injection and combustion studies. The basic methodology for the tests and subsequent image processing has been discussed, together with some limitations to be taken into account. The results show that endoscopy can provide additional information about some important processes related to the development... View full abstract»

• ### Fuel characterisation for pulverised coal combustion

Publication Year: 2000, Page(s):2/1 - 213
| | PDF (724 KB)

Two inherent challenges in coal characterisation for pulverised fuel (PF) combustion which this paper addresses are: (a) the very large scale and severe conditions at which PF combustion takes place, (b) the heterogeneous and diverse properties that coal, as a natural material, displays. Since it is not possible to reproduce full scale PF combustion in the laboratory it is difficult to apply suffi... View full abstract»

• ### Measurement of emissions from offshore combustion-user's requirements

Publication Year: 2000, Page(s):7/1 - 7/3
| | PDF (276 KB)

UK offshore legislation has just been introduced that requires monitoring of pollutants from gas turbines. This has meant a marked change in culture and technology as traditionally there has been a fuel is free' mentality. Also emissions have rarely been measured. The remote location of offshore platforms means that unique solutions are required, especially regarding any changes in the plant that... View full abstract»

A system for optically monitoring flames in large power plant boilers that indicates not only if the flames are present but also provides an indication of combustion quality View full abstract»

• ### Robust instrumentation for high accuracy temperature measurement

Publication Year: 2000, Page(s):10/1 - 10/4
| | PDF (304 KB)

A robust, highly stable, resistance thermometry instrument has been developed for use in the on-board calibration system of a space-borne infrared radiometer. At the beginning of its life, the reproducibility has been demonstrated to be better than 2.5 mK. The instrument uses an AC bridge based on novel miniature inductive components and nonelectromechanical inter-stage switching which results in ... View full abstract»

• ### All-optoelectronic sensors for combustion-related processes

Publication Year: 2000, Page(s):8/1 - 8/4
| | PDF (448 KB)

Control of combustion processes can be enabled by monitoring the spatial distribution of chemical species, imaged by an appropriate tomographic technique. The overall performance of a system for optical tomographic imaging is determined by the performance of the individual sensors. Two particular sensor designs, based on optical beam attenuation have been investigated for in-situ and real-time mon... View full abstract»

• ### A combustion scientist's view of thermocouple temperature measurement

Publication Year: 2000, Page(s):11/1 - 11/4
| | PDF (268 KB)

This paper is concerned with applications of thermoelectric thermometry to certain combustion applications. The author is of the view that in such applications all due care in setting up and operating thermocouple circuits should be taken. However, in combustion applications perhaps more than in most others, measurement errors having their origin in such things as calibration uncertainties and unw... View full abstract»

• ### Imaging combustion using electrical capacitance tomography

Publication Year: 2000, Page(s):12/1 - 12/4
| | PDF (460 KB)

It is well known that flames are rich in charged particles, ions and free electrons and such electrical activity will modify the permittivity and conductivity of the reaction zone. Work at UMIST over the past decade has led to the development of sensitive circuitry to detect such electrical changes within an enclosed volume. A commercially available electrical capacitance tomography (ECT) system, ... View full abstract»

• ### PF flow meter demonstration trials on a 500 MWe boiler

Publication Year: 2000, Page(s):1/1 - 1/6
| | PDF (512 KB)

Since the installation of low NOx burners, the optimisation and control of PF distribution and PF size distribution have assumed greater significance. Balanced PF distribution and satisfactory fineness are two of the fundamental criteria for effective low NOx burner operation in terms of both NO, and combustion efficiency (carbon in ash). Maldistribution of fuel between burners caused by fuel ropi... View full abstract»
