The weather-cam footage looked a bit flamey. I don't think it was steam.

Yeah, but that's just a gas explosion. Boilers are heavy pressure vessels. The burner could blow out and cause an explosion destroying the building, leaving the boiler tank sitting on its stand (less some insulation). Boiler explosions are a whole different thing - a (typically structurally-compromised) tank explodes due to reaching its pressure limit.
