40 CFR § 63.7575 - What definitions apply to this subpart

For boilers and process heaters that co-fire natural gas or refinery gas with a solid or liquid fuel, the load fraction is determined by the actual heat input of the solid or liquid fuel divided by heat input of the solid or liquid fuel fired during the performance test (e.g., if the performance test was conducted at 100 percent solid fuel

Equipment Design. The hot vapor to be condensed travels through a series of finned copper tubes. Fans force air to circulate around the tubes, and this air removes heat from the vapor. The resulting condensate drips down the tubing into a reservoir or out a drain. Condensers can be designed for one or two stages, as shown on the left.
