ENERGY & FUEL FLOW

Burner and Combustion engineers specify the capacity of heating and combustion equipment in terms of energy or heat input. Engineers installing combustion plant need to install asscociated fuel supply systems and pipelines that have sufficient carrying capacity to match the performance of the equipment. The following table is intended to assist engineers that need to convert specified energy and heat ratings into fuel volumes
