Waste-Oil Boilers

Waste-Oil Boilers

Waste-Oil Boilers

Anyone have experience with heating hot water waste oil boilers? I've seen them installed in automotive repair garages, but I don't have any practical design / construction experience with them. I proposed using them in a project similar in building type, but the owner shot it down because they are a "pain to maintain". However, if waste oil is readily available, and fuel oil / diesel is already on site in sufficient quantity as a backup source, it seems very feasible. Also, anyone know of the premium you pay to go from fuel oil to waste-oil capable boilers?

Thank you.

RE: Waste-Oil Boilers

Define "waste oil".

Vegetable / cooking oils?
Dirty, carbonised Vehicle waste lubricating oil?
Something from a ship?

Filtrations, and variance in quality are two issues never mind the extra air you need to prevent coking and soot formation.

Like most things if you know what you're burning you can make the system accept it, but it's not a common fuel in a domestic / small industrial setting.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Automotive waste-oil from engine oil changes.

You must not be in California where the Air Quality Board would dispatch black helicopters to have you picked up and taken to a re-education camp for even considering this.

Do check with your local AHJ before spending much effort in this.

RE: Waste-Oil Boilers

The forced air variety of waste oil heater is likely to be more common and available than a boiler system. A quick Googling of "waste oil heater" will produce sufficient results.

These used to be very common in automotive shops, more as a back-up than a main system.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

RE: Waste-Oil Boilers

I think that the OP is incorrect. What I believe he is to say is that garages have waste oil as fuel for suspended heater, boilers or furnaces. Clean Burn is one of the leading manufacturers of waste oil burners.

RE: Waste-Oil Boilers

Also if you intend to have such a set, I suggest that you have two filters in series since waste oil can be very dirty and would clog up the burner nozzle.

RE: Waste-Oil Boilers

Either keep many spare oil filters or spare filters and nozzles

RE: Waste-Oil Boilers

Willard3's suggestion is good but labor intensive.

White Paper - Effects of AIA Quick Guide to UL 489 or UL 1077
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
