B&W Marine Diesel

This is an eight cylinder double acting opposed piston diesel engine, type DM884ws-150, built by Burmeister and Wain in 1933 for the H C Orsted Power Station in Copenhagen. For 30 years it was the most powerful in the world. It is still in running order and started on the first Sunday of each month for visitors to the DieselHouse Museum
Cyl bore 840mm stroke 1500 mm rpm 115

This is not a marine engine.Its in the powerehouse in copenhagen denmrk

@916fanatic1. This is the only working engine left of its type. A marine engine in a shore based power station. If you had been to sea as an engineer at the time. This is the type of engine you would have worked on. To be able to see this in power house start up once a month is a credit to the Danish Authorities.

Why is this so quiet? I thought an engine of this size would sound like 10 times as loud as a loco engine or a ships engine.

[steviejlyons]

Probably because its is only a film clip on youtube. I can assure you that the engineer at the controls is not wearing ear defenders to enhance his looks. Obviously you have never been in a marine engine room....

Worlds bigget diesel engine for 40 years. 8 cylinders 15000 kW at 115 rpm (normal operating range) Bore 840 mm Stroke 1500 mm Built in 1932 enginenumber 2000 flywheel weighs 80 ton crankshaft weighs 140 ton engine weighs 1400 ton enginelength 24,5 meter & 12,5 meter tall 4 roots blowers deliver 1800 cubicmeters of scavengeair a minute, lubrication consists of 40 ton coolingoil which enters the engine 10 times a hour. I have the datasheet for this engine + some technical drawings!

I would like to see these

I used to work for MAN B&W next door to this old girl. You're never in doubt when it starts up - black smoke comes bellying out of the chimney for about 15 minutes, and then it turns cleaner as the engine heats up.

It is actually still in service. It works as emergency generator, so if for any reason the power plants fail and can't provide power, this old girl starts up and provides emergency power for central Copenhagen... and ensures that the power plants can get back online.

This engine is not running. It is being pushed by compressed air. That is what all the hiss is about. Large engines like these may be started moving with compressed air. Then the fuel is injected and the engine turns on its own after belching smoke. It gets a lot noisier, too.

@CE750  You'd wonder, wouldn't you?! There seem to be some jossers who get their jollies in life by pushing doors marked 'Pull' then bitching about poor design.

Why would 6 people dislike this? What drugs are they on?

[partykazer]

What we see moving : Is that the exhaust valve?

[james3765733]

This is very beautiful, thank you for sharing.

[Level5chris]

whats the fuel consumption? 

[916fanatic1]

It was purposely designed for a shore based application,And b&w did not have any marine engines that big in 1932.Most ship power was steam turbine,reciprocating and turboelectric.It is NOT a marine engine.

[supermalibug]

Must say that I later worked on a B&W single effect ( with the exhaust valve on top) and that this engine is far much more comfortable and reliable from th point of view of a marine engineer
