Studies of hydrogen combustion in an intermediate-scale test facility
Combustion of hydrogen-air-steam mixtures has been studied in a 2.3-m (8 ft) diameter sphere and in a pipe-sphere combination consisting of a 0.3-m (1 ft) diameter, 6-m (20 ft) long pipe connected to the sphere. The range of concentrations investigated included 4 to 42% hydrogen and up to 40% steam by volume. Most of the experiments were conducted at 100/sup 0/C and near-atmospheric pressure (approx. 98 kPa) although some experiments were also performed at room temperature. The effects of fan-induced turbulence were investigated qualitatively. In some experiments, gratings in the form of perforated sheets were placed in the sphere to assess their effect on combustion. Combustible mixtures in the sphere, alone, were ignited either at the bottom, centre, or top with a single electric spark. To evaluate the effects of volume geometry on combustion, hydrogen-air mixtures were ignited either at the pipe end or at the sphere centre. The effects on combustion of concentration differences between the gases in the pipe and in the sphere were investigated by placing a rupture disc in the pipe near its junction with the sphere. Discussion of the experimental results is presented.
