Safety precautions to be observed with cooled premixed gases.

Effects of cooling on the safety of premixed gases.

Methyldopa in Treatment of Severe Toxaemia of Pregnancy.

It is known that 50% N20 and 50% 02 mixture is a safe and efficient analgesic for parturient women. The British Oxygen Company have produced single cylinders of premixed gases containing a 50/50 gas and oxygen mixture, which would be ideal for use in midwifery if they could be relied upon to dispense a constant 50/50 mixture. Composition changes in premixed gas and oxygen mixtures have been rep...

The effects of added hydrogen to the premixed of methane and air in a MEMS channel

In this paper, the effect of adding hydrogen to the composition of methane and air in a micro combustor is investigated by a three-dimensional numerical method. First, the results of the current study in determining the wall temperature of the micro combustion chamber are compared with those obtained from the experimental and numerical results of the previous research. By confirming the numeric...

Simulation of Dual Fuel Combustion of Direct Injection Engine with Variable Natural Gas Premixed Ratio

Nowadays, the major challenge of diesel engines development is simultaneous nitrogen oxides and soot emissions reduction without the thermal efficiency drop. Hence, different combustion concepts should be investigated to reach optimum emission and performance conditions in diesel engines without expensive aftertreatment systems. This paper presents the results of a study on a dual fuel (DF) eng...

Measurements and Modeling of Flue Height Influence on Air Pollution Emissions and Thermal Efficiency of Natural Draught Gas Fired Boilers

This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...
