There are a number of steps determining the proper subcategory of your boiler. The first step is to verify whether your boiler is an area source or a major source. If your facility emits 10 or more tons per year of any single air toxic or 25 tons or more per year of any combination of air toxics, you are subject to the Major Source Rule.

DIN Standard Flanges vs ASME Flange Ratings - ASME

E.g, you have a # 150 flange at ambient temp on a line which has a PN 10 flange. This (the PN10 flange) is the lowest rated bit of kit on that line. The PN 10 flange therefore limits the pressure rating of that line to 10 bar, not the 19 bar that the #150 flange could stand.

HVAC Chilled Water Distribution Schemes

the operation becomes inefficient as the chillers must remain “on-line” to satisfy the building load. This increases plant’s energy usage and compounding the problem, when chillers are not optimally loaded, these are less efficient consuming higher energy rate per ton of cooling (i.e., kW per ton).

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

The energy loss can be reduced by using a high turndown burner (10:1), which keeps the boiler on even at low firing rates. Every time the boiler cycles off, before it comes back on, it must go through a specific start-up sequence for safety assurance. It takes between one to two minutes to get the boiler …
