The model OT250 fuel tank is a 250-gallon, singlewall, indoor, UL-listed fuel oil tank. Oil tanks often eliminate needed work and storage space, but the model OT-250 oil tank is designed with a work bench top that allows the tank itself to be used as a work area. The tank has a large (12-1/2 sq ft) work surface with 2" side and rear retainer lips and 3" legs for "toe space." Tank construction is of 12-gauge carbon steel with all welded seams. The painted exterior coordinates with Reznor® oil-fired heaters. The Reznor® OT-250 fuel tank is also engineered to facilitate installation. The support legs provide convenient space for forklift handling. Each tank has the following connection ports -- 2" supply, 2" gauge, 2" vent, 4" emergency vent and 1" drain. Each port has heavy duty forged threads.
Reznor® Model RAB Series Used Oil Boilers are available in two sizes with BTUH inputs of 350,000 and 500,000. The boilers are equipped with burners that are designed to burn used oil but will also burn No. 2 fuel oil. The used oil must be no heavier than 50 weight and not lighter than No. 2 fuel oil.
The boiler is made of GL-180M silicone injected, gray cast iron giving it excellent corrosion resistance, flexibility, and high thermal conductivity. The double wall sectional construction allows for a high efficiency three pass heat exchanger. Flue ways are sealed gas-tight with tongue and groove designed sections and elastic high temperature sealing rope. The unique water flow pattern eliminates thermal shock by using supply water to preheat the return water before it enters the main heat exchanger. Under normal conditions, there is no minimum return water temperature and no minimum flow requirements. A minimum supply temperature of 122°F must be maintained during burner operation. (NOTE: If the application could include a return with the temperature of ice water, maintain 158°F in the boiler.) Internal water circulation and injection combined with deflection plates ensure condensate-free boiler operation under no-flow conditions.
Typical examples are lubrication products found in the maintenance and service facilities for automobiles, trucks, heavy equipment, fleets, etc. These could consist of any combination of engine oil, transmission fluids, hydraulic oils, and even gear lubes and other acceptable lubricants that have been used.
Any firm generating acceptable quantities of waste oil, and having a need for facility heating or process hot water, is a candidate for waste oil heating. This could include everything from large fleet shops, automobile, truck and heavy equipment dealers and service centers, fast lubes, greenhouses, agricultural facilities, and even small garages.
The Federal EPA has designated typical waste oil as acceptable fuel, to be utilized as such in onsite recycling. A heater, furnace or boiler size limit of 500,000 BTU maximum input is required. Other than that, the facility is to recycle the waste oils generated onsite or dropped off at the site by those who change their own oils, and the combustion gases must be exhausted to the outside. States, counties or municipalities may have their own requirements, but usually follow Federal guidelines. In some instances, a permit to operate a waste oil heater, furnace or boiler may be necessary.
