MEs, power conversion question; re, steam boiler.

So I'm looking at the specs for this steam boiler and it is rated at 1,852,000 btu/hour (see page 8 model 24-12). The spec sheet shows that 1,852,000 btu/hour = 55.3 Hp.
However, when I go to this online unit conversation website; LINK and convert 1,852,000 btu/hour to Hp the conversion says;
1,852,000 btu/hour = 728 Hp

One HP is around 2,500 btu, straight math homie.
ETA: know nothing of this boiler, but it is listed as gross output. HP must be rated off of some other calc.

Agree, but then why does the spec sheet for the boiler say 1,852,000 btu/hour = 55.3 Hp.

According to the Internet (which is never wrong) 55.3 hp = 1,851,000 British thermal units per hour
Posted on 3/29/14 at 10:04 am to GumboPot
The rating the manufacturer gives is in boiler horsepower, which is the power required to boil 34.5 pounds of water in 1 hour at atmospheric pressure and is about 10000 Watts and a Watt is about 3 BTU/hr, so 1 boiler hp is roughly 30000 BTU/hr, giving about 60 boiler hp for a boiler with a duty of about 1,800,000 BTU/hr (I said duty).
The conversion site is using the standard definition of a hp, which is about 750 Watts, or about 2400 BTU/hr. 1,800,000 BTU/hr divided by 2400 BTU/hr is about 750 hp.
And there's your answer.

Thanks dude.

Boiler HP and thermal HP are different

No problem. I bill out at $150/hr.
Who should I invoice?

Simply:
One boiler horsepower is defined as 33,475 BTU/hr.
So 1,852,000 BTU/hr / 33,475 BTU/hr = 55.3 Boiler HP.
