HB Smith Boiler Series 34. 340-1 Heating Capacity?

johnnyrockett

I have an old HB Smith Series 34. 340-1 Mills water boiler. I believe it's 8 sections. Any ideas on what the heating capacity is? I can't find anything online. Thank you.

Is this for finding a replacement boiler? Have you done a heatloss? You never know whether the old boiler was properly sized for the building until you figure out exactly what you need.--NBC

Yep did a heat loss and everything. Customer just wants to know existing vs what I came up with.

I once looked at a disaster with a Smith Boiler with a red jacket. There was absolutely no name plate on it anywhere. No way to know what it was even, or how big or small it was. Maybe Smith sold a undercover line. I remember that it was 8 sections and the size of a Weil-Mclain 62 series.

I still have all those old Smith ratings but my stuff it's at work. I will post it tomorrow morning when I go in

Wow thank you. I appreciate it.

The old 340 starts at 6 sections being the smallest and 14 sections being the largest. I am going to give you ratings for each size boiler as follows: sections/input mbh/net square ft of steam. Here we go:
6/855/2130
7/1020/2540
8/1185/2950
9/1350/3355
10/1510/3750
11/1662/4180
12/1848/4620
13/1980/5040
14/2145/5480

How close was the old boiler sized to the heatloss?--NBC
