The Hartford Loop on Steam Boilers Definition, function

The Hartford Loop: this article gives a defnition of the Hartford Loop used on steam heating systems, explains why the Hartford Loop is necessary to protect against steam boiler damage, and gives a bit of the history of the development of the Hartford loop. We include sketches and photographs of the Hartford Loop piping arrangement on steam boilers and list inspection & defect points of interest.

The Closed System | | DIY Radiant Floor Heating | Radiant

As you can see, this allows the boiler to heat a tank of potable water, which in turn can provide domestic hot water AND floor heating (in an open or closed configuration). The water from the boiler to this heat exchanger flows 24 hours a day in a closed loop, making the heat exchanger continuously active (i.e. always hot).

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.

Heat exchanger - Wikipedia

A heat exchanger is a system used to transfer heat between two or more fluids.Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural
