Abstract
A plate burner for combusting hydrogen with air as an oxidizer forms a wall portion of a combustion chamber for example of a gas turbine. The plate burner is so constructed that air and hydrogen are separately guided to the downstream surface area facing into the combustion chamber for forming a large number of diffusive microcombustion flames, thus achieving a very low mixing scale simultaneously with a high nixing intensity. The number of diffusive micorcombustion flames is so selected that the NO,content in the exhaust gas from the combustion chamber is at the most 10×10,cubic foot per cubic foot of exhaust gas. The hydrogen enters the entrance area into the combustion chamber either through a porous wall, and air is injected into the hydrogen environment to form inverse diffusive microcombustion flames or the hydrogen is injected through a multitude of fine holes into high velocity air jets forming regular diffusion flames. In both instances, the formation of NO,in the exhaust gas during combustion is reduced to the above level or below.
