In order to make efficient use of energy resources, optimum design and development of new combustors are extremely important. In particular, emission and energy efficiencies are becoming very important considerations. A heating system incorporating a newly developed combustor was used to supply warm air and moisture to the control atmosphere in a greenhouse. We developed a high-performance combustor (80-kw type) which makes use of fuel-air counter flow. We confirmed experimentally that the combustor provided an 17% reduction in fuel cost, as compared to the current fuel-air conical supply combustor. NO_x composition measured in the flue gas was as small as 6ppm. The counter airflow nozzle design method is discussed herein.
