dust explosion venting of small vessels and Flameless venting
Process Safety and Environmental Protection, 2013Co-Authors: P HolbrowAbstract:Abstract Dust explosion venting is an established method of protecting against damaging explosion over-pressures, and guidance is available for many industrial situations. However, there is a need to: (a) establish the venting requirements of small vessels and whether current guidance and predictions in BS EN 14491:2006 need revising, and (b) improve understanding of the potential and limitations of Flameless venting. This paper describes initial results from an ongoing programme of research. Small vessel tests are carried out using cornflour and wood dust on: a commercial sieve unit, a commercial cyclone, and a 0.5 m3 test vessel with explosion-relief openings without vent covers. Initial 0.5 m3 vessel tests give reduced explosion pressures that are lower than those predicted. This is because the predicted pressures are based on openings with vent covers. The reduced explosion pressures measured in the sieve unit and the cyclone are also less than predicted: the reasons are discussed. Flameless vesting tests are carried out using cornflour and wheat flour on a commercial Flame Arrestor unit. Initial tests demonstrate benefits, particularly a high level of Flame extinguishment, but a problem of reduced venting efficiency compared to conventional venting. These initial results indicate that further research is needed.

development and application of in line Flame Arrestor on coking gas engine
Internal Combustion Engine & Powerplant, 2012Co-Authors: M A XiaozhongAbstract:Coking gas generally contains hydrogen a bit much,so these problems like backfiring in combustion chamber and gas detonation in the intake pipe happen sometimes,causing engine not operate normally.Based on the theoretical research results that Flame quenches against cold walls,the metal ribbon Flame arrester is developed,which is used in the intake system of the coking gas engine to prevent backfiring and protect effectively the components in intake system against being damaged and ensure that the engine can work safely and reliably.

application research on the steel bellows Flame Arrestor in gas engine
Internal Combustion Engine & Powerplant, 2007Co-Authors: M A XiaozhongAbstract:For energy and environment,gas engines is applied widely.Most of the gas engines are modified on the base of diesel engine or gasoline engine,where fuel is pro-mixed outside the cylinder.In this gas engine,mixture gas in cylinder backfires easily and destroys spare parts in the intake system.On the base of the technology of Flame "Cool-wall and bulk quenching ",the steel bellows Flame Arrestor is developed and mounted in the intake system,which solves the problems that the intercooler or other spare parts is damages resulted from backfiring and make the gas engine operating reliably.

method for preparing Flame Arrestor for coke gas oven
Applied Mechanics and Materials, 2004Co-Authors: Zhang FeiyaAbstract:This paper intends to introduce a Flame Arrestor for combustible gas pipe developed by the authors according to the experimental research on the explosibility and Flame propagation behavior of simulative coke gas oven in a pipe system. The Flame Arrestor is composed of crimped ribbon, wire netting and shell. Experiments show that the Flame arrester can satisfy the technical requirements of fire prevention and explosion protection. It can be used in the areas with the hazard of gas fire and explosion.

USING HYDROGEN AS A FUEL IN AUTOMOTIVE ENGINES - AN INVESTIGATION
International Journal of Innovative Technology and Research, 2013Co-Authors: Annamalai K., Pradeepkuma A.r.Abstract:In the fast moving world, hydrocarbon based fuels have become significant for a century’s development. The fuels derived from crude oil are critical source of energy for fueling vehicles. However, crude oil based fuels are non renewable. The present investigation of using hydrogen was carried out in a direct injection diesel engine having a compression ratio of 17.5:1 and a capacity of 5.9 kW at a rated speed of 1800 rpm. In this investigation, the hydrogen was fed to the engine through the inlet manifold along with intake air during suction stroke of the engine. In order to maintain safety, the Flame trap and Flame Arrestor were also used in the experimental setup. The results shows that there is an increase in brake thermal efficiency of the engine and reduction in carbon monoxide emission when, the hydrogen is used as a dual fuel, in the operation of the diesel engine

Flame Arrestor for gas mixtures containing hydrogen
Petroleum Refinery Engineering, 2012Co-Authors: Sinopec LuoyangAbstract:In petrochemical plants,fuel gas is often a mixture containing hydrogen.The maximum experiment safety gap(MESG) is 0.29 when the hydrogen in mixture gas is 27% and explosion class is Ⅱ C.As the hydrogen in fuel gas in petrochemical equipment is lower than 27%,the MESG of fuel gas should be greater than 0.29.The study of applicable national and industrial codes and standards as well as the analysis of class of explosion-proof Flame Arrestor for gas mixture containing H2 conclude that the explosion class of Flame Arrestor should be lower than Ⅱ C,i.e.either Ⅱ A or Ⅱ B.The most accurate way is to send the data of compositions of gas mixture and operation conditions to qualified institutions to determine MESG based upon the experiment in accordance with GB 3836.11 and explosion class of gas mixture containing H2 based upon MESG.
