Oil firing steam locomotives

[Lone Cat]

1. When was the first time it is shown up?
2. Does it still needs belpaire firebox?
3. Traditional oil firing steam locomotives burn 'heavy' fuel oil. (No. 5 or No. 6 i think). the 21st century modern steam projects while themselves try (so hard) to evade petroleum dependency. many of them actually 'favors' what they call 'light oil firing'. for the DLM it means that their steam locomotives burn heating oil (No. 2 fuel oil?), the system which completely eliminates fuel oil heating steam coils required to keep heavier fuel oils (fuels of the traditional oil firing steamers) flowing. but given that the carbon emission and petroleum prices are now a BIG issue. 'organic' fuels saw some interests, scientists and engineers proposed that biofuels can evade (or eliminates) petroleum dependency and decrease carbon footprints to the near perfection (how?) . when one says Biofuels the first priority was Biodiesels, which can be made out of organic oils (and this includes waste (cooking) oil derived from kitchen!), diesel engine fuel injectors were too fragine so that such raw organic oils must go through so those organic oils must go through some chemical reactions and some other processes first. for steam engines however, these organic oils needs only filtering and voila!

Carbon neutrality

A power unit based on advanced steam technology burning hydrocarbon fuel will, like any heat engine using hydrocarbon fuel combustion, inevitably emit carbon dioxide, a long-lasting greenhouse gas. However, significant reductions, compared to other combustion technologies, of other pollutants such as CO and NOx are achievable by steam technology, which does not involve explosive combustion,[12] without the need for add-ons such as filters etc. or special preparation of fuel.

If renewable fuel such as wood or other biofuel is used then the system could be carbon neutral. The use of biofuel remains controversial; however, liquid biofuels are easier to manufacture for steam plant than for diesels as they do not demand the stringent fuel standards required to protect diesel injectors.

^ waste cooking oil burner without preheatings but still operatible.


^ DLM Modern steam locomotive schematics. it is indeed intended to burn light (and clean) fuel oil (or maybe waste oil?)

So then do you really think that the project crews of these modern steam locomotives intends to use waste cook oil for their trains?
