As the used-oil heating equipment market leader, Clean Burn has more certified engineers on staff constantly improving and creating new used-oil furnaces, boilers, recycling centers, and storage tanks than any other manufacturer. A lot of technical expertise is required for the world’s largest selection of used-oil heating systems.
Another reason Clean Burn is the industry leader is the brand’s focus. Clean Burn doesn’t make dryers, parts washers, lifts, or any other type of shop equipment—just quality, durable, long-lasting heating equipment. As you make the important decision on which used-oil furnace or boiler to buy, keep that in mind. To Clean Burn, a used-oil furnace or boiler is too important to be an afterthought.
The Clean Burn Heat Exchanger
It’s simple physics: the more surface area exposed to a combustion chamber, the more heat you will capture. The more time room air circulates around a heated surface, the warmer it becomes.
There’s nothing else in the world like the remarkable Clean Burn Heat Exchanger. Compared to inexpensive Blast Tube furnaces, which feature a simple cylinder shaped combustion chamber, a Clean Burn Heat Exchanger provides approximately 200% more surface area for capturing combustion heat. You get more heat from less oil. The result is a lower stack temperature, more economical use of your used oil, easier maintenance, and longer service life.
The Clean Burn Pump
The oil pump is a key component in any used-oil furnace. As every mechanic knows, it is better to have a heavy duty component that doesn’t have to work to the limit of its ability over time. That is why the Clean Burn Pump is made to be so durable.
Compared with competitive units with plastic gears and overworked electric motors requiring fan cooling, the Clean Burn Pump features heavy duty steel gears encased in an oil bath as well as precision assembly to help ensure a very long, very reliable service life. Oil flow is consistently held because precise gear ratios and pump speeds are set for each individual furnace. This maintains correct flow rates no matter what type of oil and viscosity is used and provides for optimum performance.
In short, if you were building your own used-oil furnace, you would choose a Clean Burn Pump—no question.
Advanced Burner Design
Unlike standard fuel oil, used oil must be pre-heated in order to ignite properly, and it has a higher flash point. Some used-oil furnaces are modified fuel oil burners, but that approach simply isn’t good enough for Clean Burn customers.
The Clean Burn burner is engineered from the ground up exclusively to burn used oils, and it burns standard fuel oil for added versatility. The pre-heater block heats oil and air to the same precise temperature for efficient combustion. The mixture is ignited at the burner retention head where additional combustion air is added, which swirls in a carefully calculated pattern to maximize combustion efficiency and help make flame control easier.
The special retention head creates more air turbulence at the point of ignition to generate a larger, more efficient flame, making operation more reliable and more forgiving for burning used oils.
Used-oil furnaces that use modified Beckett fuel oil burners (which are outstanding when used with standard fuel oil) are much more susceptible to nuisance flame-outs or shutdowns. Clean Burn furnaces are legendary for reliability; the burner system is one good reason why. The unique modular design of the Clean Burn burner also makes service faster and easier.
Swedged, Not Welded
A swedge is a way of joining metal parts without welding. Welded joints are susceptible to cracking and failing in a combustion chamber environment. The tubes in the Clean Burn Heat Exchanger system are not welded together, but swedged, allowing the metal parts to expand and contract with minimum metal fatigue. This means added years of reliability and service life for your Clean Burn furnace.
