Power Generation By Utilizing The Compound Gases With Spilled Oil At Using Power Chimney Techniques

The power chimney tower is one of modern promised energy which may be developed by low losses, simple and has high facilities. In this paper, many parameters were studied exactly which influenced the prediction of system operation and fundamentally depend on the combustion of gases compound the spilled oil. Velocity distribution is the important parameter which gives the first prediction to put the position of erection of power turbine, made or not. The numerical analysis was presented by using GAMBIT and FLUENT 6.3 to predict that high velocity at the expansion of chimney near the centre of burned gases cover collector. This position is very suitable for promoting and building the power turbine since the velocity was more than (33 m/s) when the compounded gases is combusted (that there components are the methane gas with other friendly gases and waste. It is easy to erect steam or gaseous boiler in contact with furnace for utilize the heat generated in electrical power generation. So, the other factors, temperature and pressure were studied to coincide with previous papers in this field.

This technology was first described by Gǜnter in 1931 and tested with the 50 kw Manzanares prototype plant since 1980 [1]. There are four components for the combination of this prototype: combustion chamber, chimney, turbine connected with electrical generator. The installation of power chimney at locations near the oil spilling stations for utilizing of compound gases which burned in this suggested power plant. The compound gases pass through burner vent which circumstances with air vent to create high mixing rate to combust inside the cub of combustion chamber. The air near the ground absorbs the heat to decrease its density. The hot air particles move up to hit the cub ceiling continuously and go to chimney vent. This series Journal Of Petoleum Research & Studies 1 st Iraq Oil & Gas Conference (1 IOGC) E47 heating generates continuous movement of air, then, generates electrical energy by installing turbine connected to electrical generator. The height of chimney causes high pressure difference between the upper and lower points. This pushes increasingly the movement of air particles between the lower points of chimney to up. In addition, the power may be generated by connecting gas or steam turbine to use the resulting hot gases before chimney inlet vent. Gaseous fuels are usually characterized by clean combustion, with low rates ofsoot and nitric oxides. The main problem is achieving the optimal level ofmixing in the combustion zone. A mixing rate that is too high produces narrowstability limits, but a mixing rate that is too low may make the system prone tocombustion-induced pressure oscillations. Many different methods have been used to inject gas into conventional combustion chambers, including plain orifices, slot, swirlers, and venture nozzles [2]. Backstrom and Fluri [3] developed two analyses for finding the optimal ratio of turbine pressure drop to available pressure drop in a chimney power plant to be 2/3 for maximum fluid power and using the power law model for this prediction. Haafet al. [4] , Haaf [5] and Schlaich [6] described the operation and presented results for a prototype solar chimney power plant built in Manzanares, Spain in 1982. Pretorius and Kröger [7] evaluated the influence of a recently developed convective heat transfer equation, more accurate turbine inlet loss coefficient, the performance of a large scale chimney power plant. This simulation of study concluded that the new heat transfer equation reduce the annual plant power output by 11.7%, but , the more realistic turbine inlet loss coefficient only accounts for a 0.66 ̊rise in annual power production. Journal Of Petoleum Research & Studies 1 st Iraq Oil & Gas Conference (1 IOGC) E48 Ninic and Nizetic [8] developed and use the availability of warm, humid air via the formation of up draft “gravitational vortex column” situated over turbine with numerical solution for chimney power plant. Sislian et.al. (1988) [9] measured experimentally many mechanical parameters in combustor and concluded that turbulence in the jet diffusion flamewas appreciably more anisotropic than in the corresponding cold jet in all regions ofthe flow. Love et.al. (2009) [10] developed an experimental method for the rapid characterization of combustion properties, and measured the amounts of NOx and combustion products,Azazi (2001)[11] presented a study to Hartha power plant furnace in Iraq, useda two dimensional aerodynamics and thermal aspects by using FORTRAN computer program. He concluded that 1500 oC inside temperature of furnace and the tangential velocity played a great role for keeping the stability of the fire ball. Alhabbubi (2002) [12] presented a prediction of temperature distribution and heat flux along the walls of Al-Mussaib thermal power plant furnace in Iraq by usingzonal method to analyze the radiative heat transfer. He found the temperature range from 1450K to 2100 K.Sobolev et.al. (2008)[13] presented a numerical calculation results of methane turbulent diffusion jet flames of rectilinear-swirl burner in the furnace of high capacity boiler by using CFD AnsysCFX10.0 program. Hannun (2009) [14] studied the combustion of liquid and gaseous fuel in Nassiriya power plant furnace, analyzed numerically the mechanical properties by using FLUENT code,Hannun et.al. (2011) [15] presented a prediction for mechanical parameters influenced the operation of solar power chimney at Nassiriya city.
