Re: Oil fired boiler explosion

The whole point of the fan starting well before ignition and oil feed is to blow out any combustible gasses to prevent such an explosion. Should the burner fail, a good control system will keep the fan running and attempt ignition again only after 10 seconds or so, to allow all the unburnt fuel vapo...

Re: Towing weight - Frolic 18

Hi James Our boat Grayling is 19' long and we have a good estimate that it is 1.3 Tonnes with trailer and a few extra items. A Frolic is lighter in build but I would guess at 1 tonne for boat and trailer, with some extra items which you always take with you. Half a tonne seems a little on the small ...

Re: UK boiler regulations

Hi Steve From what I gather the rules and regs for small steam launches are more or less the same as for models. The big difference being the SBA had set up a company called SBA Services who are there to help and support people on the boiler side, with approved designs, inspections, guidance etc. Th...

Re: building a steam condenser

Running with a condenser but without an air pump to create vacuum is not common in the UK, but it does add a fair bit more complexity. Another thing to think about is a hot-hotwell. If your hotwell is pretty hot, the vacuum generated by the feed pump by the inertia of the water and any pressure drop...

Re: building a steam condenser

In terms of size, you can never have it too large. Given an ideal air pump, which can create an absolute vacuum, then the limiting factor for the vacuum it can create is dependant on the temperature of the water entering it. E.g. if your condensate was 60C, the vacuum generated cannot be greater tha...

Re: Nuts and Bolts

I have found these to go well together: Stainless nut onto Stainless thread, fine. E.g. for engine columns. Stainless nut onto Steel & BZP Steel. E.g. most common nuts and bolts. BZP Steel nuts onto BZP Steel threads clamping onto aluminium. E.g. an Aluminium cover plate. *Note that Stainless and Al...
