RANE Portable Combustion Systems

The RANE Trailer Mounted Portable Combustion System is the largest and most cost efficient portable combustion system in existence. Able to process up to 13 arms at 600gpm and as little as 1 arm at 600 gpm, while maintaining stability, with no assist gas. In many terminals, the system will be able to even provide its own pilot fuel. This unit can be set up for operation by one man, in approximately 2 hours.

Currently there are two units in operation. The first unit tested at 2mg/l, without assist gas, at a large five bay Detroit terminal and also operated successfully at a small two lane terminal with marginal vapor return. The unit continued operating very successfully thoughout the midwest: Indiana, Michigan, Kentucky and Alabama. It is expanding its operating territory to meet the demand.

The second unit is of equal capacity, but has been space and weight optimized for transport. We have used aluminum wheels and tank, and went to light weight stainless steel ducting and vapor burner piping. The combination has allowed us to carry a normal fuel load without exceeding trailer axle weight. This unit was also tested in the large Detroit terminal, and never went over 60% capacity.

We believe that the RANE Portable Burner System can meet almost any terminals vapor recovery needs as an emergency standby unit. It is a cost effective way to operate a terminal when Vapor Recovery Equipment must be down for extended maintenance.

RANE Vapor Burners are designed to meet all applicable NFPA Burner Codes. We use a Maxon LV Line Burner to maximize turndown and increase efficiency. Maxon Guillotine Block and Vent Valves are used to direct vapor flow. We use Selas Flame Checks, and Varec Flame Arrestors to safely isolate the burner and vapor blower. An AMCA B design 3600 rpm pressure blower with heavy construction, nitrile face gaskets, low leakage construction, and explosion-proof c-face flanged motor are used to minimize leakage. Burner operation is controlled through a UL approved flame safeguard. We have a secondary safety system, using sensitive pressure switches to ensure proper operation of all equipment. Operational and safety signals are channeled through a GE 90-30 PLC and operation commands, signals, operator switches, and the first out enunciator safeties are displayed on an interactive touchscreen. All high power equipment operations are conducted through machine tool and motor control relays on a isolated 110 VAC system. 460VAC/ 3 Phase Power cords and arc tight Crouse- Hinds fittings are standard.

RANE Design Criteria:

	RANE System is designed to handle 1,100cfm @ 20% vapor concentration on-line burner system, on a 50’ drop-deck, two axle, extendable trailer.
	Design utilizes an Equalizer to stabilize the returned fuel vapor concentration in the burnable mixture range. This conditioned vapor is directly burned using a variable volume Burner and can be used to fuel the Burner’s pilot.
	The burner design shall meet all applicable NFPA Codes.
	The burner must be stable with one arm loading as well as with multiple arms.
	Burner Efficiency is maintained without the need for assist gas.
