A catalyst unit for use in an exothermic reaction, such as ammonia oxidation, comprises a material effective as a catalyst for said reaction having a shape conforming to a disc or cone having a plurality of radially extending corrugations. The catalyst unit may be disposed across a reactor with a start-up burner disposed above the catalyst unit and mounted for rotation about the axis of the reactor. The burner tube is pivoted and provided with means, for example a follower engaging with the upper surface of the catalyst unit, so that as the burner is rotated about the axis the burner tube pivots to maintain the burner tube a constant distance above the upper surface of the catalyst unit.
