The gas swirling state determination system (10) determines the quality of the swirling state of gas that swirls around the central axis. The gas swirling state determination system (10) includes an imaging device (39), an information processing device (11), and a display device (42). The imaging device (39) captures swirling gas from a direction along the central axis to acquire a still image. The information processing device (11) includes a calculation unit (40), a smoothing unit (41), and a determination unit (43). The display device (42) displays a determination result.

A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying of the high protein organic waste material within the combustion chamber. Temperature and nitrogenous hydrocarbon combustion reactions within the combustion chamber are also controlled by injection of steam within the combustion chamber.
