Re: Oil burner consumption

My boat uses about 10 litres of kerosene in a day's steaming. 20' boat, around 3000lb displacement, Stuart 6A engine and a 3-drum water-tube boiler with feed preheater.

Re: chelmer river uk how do I get on it?

My posting above was done in a bit of a hurry, but for Colin and others, I can add a bit more. The first thing to say is that there is not much fresh water available for steaming in Essex and virtually none in Suffolk, although quite a lot in Norfolk - at a hefty toll from the Broads Authority. In f...

Re: chelmer river uk how do I get on it?

There appears to be a slip behind the Paper Mill Lock Tea Rooms at Little Baddow, but whether it is just private you'd need to investigate. By agreement with the proprietor of the Old Stables Tea Room. Use of the slipway should be booked through Sarah Phillips, Administration Assistant based at Pap...

Re: Fuel oil preferences

I would like to support Fred's comments on commercial high-pressure atomising burners used with Kerosene or heating fuel. They work very nicely, whereas a lot of home-made steamboat burners don't. A vapourising burner with pre-heat from denatured alcohol is an option, or at least was an option when ...

Re: Propellor tip clearance

I've been out and measured mine as it sits on a trailer by the barn. Clearance is just under 3", top and bottom above and below a 16" screw. I have no doubt the clearance is more than necessary, but the hull is a standard "Nell" from Blossom's boatyard near Oxford, and that's the way it is. Maximum ...

Re: New Stainless Economizer

I suspect that almost everyone with a steamboat is aware of the chloride enhanced stress corrosion cracking in Austenitic stainless steels. 304 is fairly prone to it, wherease 316 is often called a "marine" grade, whereas in fact it is only a factor of around ten better than 304. To be honest, I thi...

Re: How to Install Brass Trim Between Hull and Deck??

"Alpha" brass is a metallurgists term, but I don't know a more common name for it. Ordinary brass has a classic binary phase diagram, with a high copper alpha phase which is ductile and fairly soft suitable for rolling into strip; that changes rapidly with increasing zinc to the beta phase which is ...

Re: How toInstall Brass Trim Between Hull and Deck??

Most brass sold as household decorative trim is straight apha phase material, and not very well suited to salt water use. You'd be better using what we know as bronze in the UK, and I think you know as Red brass in the US. Otherwise "Naval Brass" which has 2% Molybdenum in it is good if you can get ...

Re: Pressure Washer Pumps for Feedwater

They have two issues, VERY sensitive to any sort of particle contamination in the check valves and they are difficult to disassemble without special tools. The check valves are in a plastic cartridge and pressed in. -Ron I have owned and run quite a number of them over the years, and can fully supp...

Re: Cylinder lubrication ?

They're (very) commonly called "Fat Ladies" in the UK. You can drop in a little (and I mean "a little") oil in after warming the engine and before starting, then maybe give another small shot at lunch time, and a final dollop when shutting down. The fat part of the oiler can have a much smaller quan...
