Show THE DEVELOPMENT OF AN OXYGEN-PULVERISED FUEL BURNER FOR ENERGY SAVINGS AND PRODUCTION INCREASES N. D. Lennox Senior Applications Engineer Air Products PLC A. C. Smith Manager - Metallurgy and Process Industries Group Air Products PLC SUMMARY This paper describes the stages of development of the oxygen-pulverised fuel burner and the concept behind its design. 1. INTRODUCTION Air Products PLC Applied Research and Development Department is committed to the development of new equipment and methods for the application of industrial gas products. Development work will normally consist of a mixture of theoretical analysis and practical test work carried out at Air Product's facilities at Crewe in conjunction with field based trial work on customer's production plant. One such customer of Air Product's, IMI Refiners limited, Jamesbridge, obtained, in mid-1987, a grant under the European Community Demonstration Project Scheme. The grant was made to IMIR to jointly undertake with Air Products and the British Coal Corporation a specific project which was titled UThe Application of Pure Oxygen and Powdered Coal Burners in large Industrial Furnaces". It is for this project that APl has developed the oxygen-pulverised fuel burner described in this paper. 2. OXYGEN IN COMBUSTION In order for the combustion of fuel to go to completion it is necessary to fulfil two criteria: 1) That there is sufficient free oxygen available to consume the fuel molecules. 2) That there is sufficient contact or residence time between fuel and oxygen molecules to allow complete combustion to take place.
