Depends if you're running a multifuel engine.

I believe they are turbine engines now.
Gas Turbines will run on most fuels, its normally a requirement for most military engines, especially battlefield ones.

They are generally multi fuel engines, not 100% sure how that works but.............

Only the septics use turbine packs in the Abrams, not a particularly solid choice by all accounts, and they aren’t overly keen on sand. British challenger uses an MTU diesel I believe

Chap I worked with put diesel in his petrol MK3 Escort and decided to top it up with petrol rather than drain it off. For about four days it was like the James Bond smoke screen in the works car park till he diluted it again.

We are on page two, and I'm not sure if I've seen anyone actually try and answer your question yet?
So, kerosene is 28sec (measurement of viscosity)
Diesel is 35sec
Who knows what petrol is...
Basically on a pressure jet central heating boiler the pump pressure and jet size are set to the viscosity of the fuel (and intended burn rate).
I mean, virtually all boilers now are 28sec only, but on the ones that can be configured to run on 35sec, this is how it's done.
Your misfuel will be constantly changing, but you could make yourself a viscosity cup to measure it. You could calibrate an unknown cup with known fuel at a known temp and then work from there.
Modern burners are quite, umm, safety conscious, in that their start up cycle runs the fan for a while before ignition, in order to vent the chamber of any residual fumes (that could be explosive).
I would suggest that, providing you took sensible precautions, there would be no issue.
Obviously, if your house burns down (for an entirely unrelated reason) and your insurance sees the IBC of misfuel wired into your boiler, you will have to figure them until long after your own death for any sort of payout at all, but, other than that....

One last thing -
The blast tubes on 35sec capable burners are, it seems, slightly different from the stubby tubes you see on all the riello 28sec boilers.
I've not been able to work out what this actually means...
(Sometimes called flame retention tube)

One of the biggest issues with putting petrol through a diesel is that it destroys the lubricity of the diesel and ends up shafting the injection pump.

If the fuel was 100% free, I'd maybe start treating the IP as a service item!
My injector pump is pressure fed with engine oil.
Its the petrol that would worry me. Seems an odd thing to run through an oil boiler?

It's not going to split out of the mix with any ease at all, and, again, all modern burners have a purge cycle prior to ignition.
Aside from insurance, it wouldn't concern me at all IF I had checked every batch to make sure it wasn't pure petrol.
Pure petrol would be way too thin, and would overdose at any given pump pressure / nozzle combination, but, aside from that, i doubt there would even be much of an issue. The whole point of the device is to ignite flammable liquid in a steel box, and the purge cycle vents potentially explosive vapor prior to ignition.
I mean half the country have gas boilers on the walls of their kitchens - that goes bang also.
Maybe I'm just wreckless, but, assuming the dosing (lpm / gph) was right, I can't see an issue.
I'm currently running my chinese 5kw diesel burner that heats one workshop on the results of a mis-fuel that destroyed the engine of the car it was in. I was going to stick it in the jcb cut with two stroke to get the lubricity up because it has a crappy old leyland 4/98 engine that will run on anything but this seemed a even better idea. Its only about 20% contaminated from some basic flash tests though.
So I've been staying warm in the shed courtesy of that. House boilers I have no idea about though. As above, I bet your insurance would have a cow if you had a claim.

Currently one of the biggest issues with hydrogen engines.

It would be, it ran at 45,000 RPM! (iirc)I once bought a Rover 1S60 whilst testing wine and browsing e-bay.
Noisy thing, ran fine on heating oil as I had no avtur.
Sold it to a loony who wanted to power a car with it.
Great little unit though. I recall doing efficiency runs on one whilst doing my apprenticeship. Came out of the Vulcan (APU) amongst others.

I remember a lecturer telling us a gas turbine would run on pulverised coal, just not for very long.

Yep, the problem is pumping it.I remember a lecturer telling us a gas turbine would run on pulverised coal, just not for very long.
