Show © Because high intensity combustion is available, the boiler can be more compact in size. ® T h e convection heat transfer in the furnace is larger than that obtained in the conventional combustion method. For cooling the burner structure, we plan to include the burner in our vacuum type hot water heater and cool the burner with the medium of heated water in heater. We consider that the flash back of premixed mixture can basically be coped with the improved shape of nozzle. A s the safety device, w e consider to provide a safety equipment that detects pressure difference, to be installed at the mixture feeder section. However, we think some more tests are required before commercialized Before closing, I would like to thank Messrs. M.Khinkis, H. Abbasi, M.Roberts, J.Rabovitser and D.Cygan of IGT for their valuable advices. References 1. Ultra-Low-Emission Burner For Boilers And Fluid Heaters by; Hamid A. Abbasi, Mark J. Khinkis, and David F.
