Big plumbing

[Kayos]

Went to visit a contractor today, who specialise in pre fabbed plant rooms, mostly skid mounted stuff

No mug or banana for scale but the buffer vessels are 24,000 litres each, the stainless setups are 1MW and the others are around 9MW

and the blue thing is the heat exchanger

and the blue thing is the heat exchanger

The big one is 9MW, there's actually 2 the same. Redundant secondary side for a whole hospital

Where's the flux capacitor?

Nice.

We skid mount a lot of our gear. Means it can be built in the workshop, dropped in place and just the interconnecting pipework and services to sort on site.

If you ever strip one of those heat exchangers, pay close attention to the order the plates go in, and measure the conpressed length before you undo the clamp screws.

Dont think I have ever seen that many strainers used on an installation, whats being pumped through it?

It's all hospital stuff so will be part of the spec. It's secondary side so will be water with inhibitors. Central plant for a de-steamed system

You have made a valuable extension to the forum's standard method of measurement with "wheelie bin for scale".

I hated servicing the heat exchangers in the paintshop, like you say, once all the plates had been cleaned, they had to go back in sequence followed by winding the clamping plate down on 8 off M24 allthreads one turn at a time to keep everything even.

Does it’d supply a hospital with fresh/re circulating water?

All heating, part of a big de-steam and decarbonisation project, being a hospital though it has complete redundancy

Good advice…hateful things…..those butter fly valves pass in about 15 minutes of use too.

So is this heating, using low pressure steam on the primary and inhibited water secondary.

The bigger and more complex stuff gets the more sense skid mounting makes. On the big stuff the skids are often commissioned and tested before installation, saving lots of man hours to make it all work on site.

Not having that, the lid is 2 3rds down the length which make it a stubby wheelie bin, not a standard gauge block wheelie bin, banana or mug

No steam, complete de-steam.

Heat pumps with gas peaking boilers, electric and oil backup plus redundancy. It cannot go offline

It does mean it's less decarbonised on paper, in reality the boilers will be extreme cold and the oil will be emergency use only

 

[addjunkie]

Ah ok….maybe more decarbonised on paper, but seems to be far more complex than a simple steam plant..

Secreted in the vorpal tunnel

Pipe porn…. Get your silicone grease out….

Steam not good, high energy, high maintenance and is really quite dangerous

Most hospitals will be de-steamed at some point

Steam high energy I agree, not the most efficient process. But your new system has 4 heat sources needing maintenance. Dangerous is relative, not convinced Id put low pressure wet steam in a dangerous category, but suppose it depends what folk are used too.

The Opex for steam is becoming unsustainable plus it is carbon intensive. With the redundancy already built in we are actually lowering maintenance costs throughout the lifecycle

Dangerous in this context relates to the operation and maintenance, it's an old technology, used because footprint Vs output was previously unmatched. It's had it's day and is being removed. We do what the client asks
