Cares when buying used equipments
(OP)
Hello everybody:
In our Diesel power plant we are planning to cogenerate with condensing steam turbines. The steam will be generated by recovering the heat of the engines exhaust gases.
Up to this moment, everything is OK but, regarding with the turbine and generator acquisition, the owners are strongly inclined to buy used (second hand or discarded) equipments, instead of brand new ones.
We are out of USA. Even when we know that this kind of trade is made on the basis of that the equipment is sold "where it is" and "as it is", what cares should be taken into account, by our side, prior to these acquisitions? Any advice on this subject will be highly appreciated.
Thanks





RE: Cares when buying used equipments
If they are just sitting out or not protected or properly provided for (or in actual service at the time of the purchase) I would be very leery of the equipment.
The generator insulation could be moisture soaked and could be hard to dry out. I would do at least PI test on the windings and a PD test as well.
This assumes that the equipment wasn't junk before it was laid up or stored.

There are plenty of independant experts/inspectors around and it might be a good idea to get one to carry out a survey of the equipment for you.
Try to use one who is a PE experienced in steam turbine generators and approved by the company who provides your plant insurance. That way you will minimise your risk.

more specially so if you have damage to rotating parts.
or you need to rewind the generator...
get a quote of how much time and monies you will need to bring the equipment to current standards and regulations so you can obtain the permits from the local authorities to operate.
cheap is expensive.

it does also happen that the oem demonstrates that using 1st quality (not knock-offs) spare parts and services is indeed more expensive than a completely new piece of equipment.
it is up to the user to decide what kind of business he/she wants to run... OEM's are not cheap...
