Pilot scale cotton gin trash energy recovery
Abstract
During the summer of 1992 a 520,000 kcal/h (2,064,400 Btu/hr) biomass combustor was installed at a cotton gin in southwestern Oklahoma. The gin has a capacity of approximately 35 bales per hour. Each bale of cotton ginned weighs about 227 kg (500 lb) and produces about 68 kg (150 lb) of trash. Therefore, this gin produces about 52,360 kg (115,500 lb) of trash per day during a typical ginning season. Approximately 2 million kg (4 million lb) of gin trash are produced at this site each year. Cotton must first be dried to about 3-5% moisture content before the ginning process is begun. To accomplish this at this gin, two six million Btu/hour direct fired gas heaters are used to heat air for drying the cotton. The biomass combustor was installed to operate in parallel with one of the heaters to supply heated air for the drying process. A pneumatic conveying system was installed to intercept a portion of the gin trash and divert it to the burner. The burner was operated during the 1992 ginning season, which lasted from September through November, with few problems.
