Boiler wanted

Dear all, I'm looking for a condemned firetube boiler of a small Merryweather/Kingdon size boiler to use as a supply for a large steamer for bending wood. It will be working at atmospheric without isolation on the steam supply so only needs to be watertight, not pressure-tight. If it needs work to m...

Re: Injector Designs?

Hi Malcolm, I'm pretty sure Martyn uses Buffalo injectors on Mosquito and the high pressure one injects just fine at 250psi- not to say he didn't make a set of nozzles to suit an existing body. Be wary going down the road of buying Penberthy copies- I bought two brand new 1/2" ons off a reasonably w...

Re: Feed into twin drum watertube boiler

Feeding into the bottom drum will tend to promote uneven temperatures within the boiler. The colder feed will tend to make a stagnant slug of water in the lower drum, because the colder water is considerably more dense than the hot saturated water. It is my understanding that this condition is why ...

Re: Feed into twin drum watertube boiler

Hi Mike, I would definitely go with the engine driven pump into the lower drum- this will aid circulation in the boiler, whereas feeding into the top drum will slow circulation and cool the best areas of steam production in the boiler. As the hand feed pump is usually used in an emergency or to top ...

Re: An appeal to help relocate TULE

Mack, Very sorry to hear your woes, they do happen, it's a matter of learning and moving on. Some points regarding the dock you plan to build as a replacement (coming from a Boatmaster's Licenseholder for up to 250pax passenger boats); - The dock you have in the pictures is set up to resist vertical...

Re: Primary leads or lags secondary?

Hi, ST 6A's can be notoriously difficult to start/reverse, especially if they have been well 'used'! Their problems are numerous, mostly connected to the issue of being far too short legged and trying to fit full size reversing valve gear onto an engine deigned for fast running in generating roles. ...

Re: What is this?

That would be the air pump- you correctly allude to it's use as the vacuum pump and maintains circulation in the condensing system. I didn't see the posts regarding the water pump being necessary, but one BIG recommendation regarding the 6A boiler feedpump- try and run it at 1/3rd engine speed- so 3...

Re: BOILER PRIMING

What has changed on the boiler and what work have you done before this problem started happening? Unlikely to be oil or impurities after such a rigorous cleaning- you can put a a SINGLE DROP of washing up liquid in and try the blowdown again. However, priming due to oil is usually down to a proper s...

Re: wet steam

The blow down procedure taught to me was slightly different; 1. Shut top and bottom Cockshutt 2. Open drain and clear the glass completely (leave drain open) 3. Open bottom cock (this fills the glass again) and blow through drain. Shut top cock (glass empties again). 4. Open top cock- any rubbish th...

Re: 90 deg-- 180 deg crank

Greg, The rods that can be seen readily are actually the con rods for the valves. The actual cylinder connecting rods are all the same length, the LP having a longer piston rod instead. I believe those are photos of Chris' engine, and crank. In some correspondence with him a while back I recall him...
