Abstract:

Using large numbers of orifices in the head of the combustor to generate independent shear layers in a co-operative array, the so-called pepperpot concept was evolved to secure efficient combustion in a weak primary zone. Specific targets were high efficiency and very low smoke at both low and high power levels when burning either kerosine or diesel fuels. Performance tests of a pepperpot demonstrator combustor at representative conditions of idle, intermediate and high power using both fuels are described. An impressive combustion performance has been realised over the whole power range, together with excellent exit traverse quality and tolerance to fuel type. Author
