28/2/2018 · I figured I'd have a go at calculating the standby heat loss of my boiler. For a back of the envelope calculation -- quite reasonable, and quite correct. Just round it off to around 20,000 BTU/hour. As @EBEBRATT-Ed noted, some of that is wandering off up the stack -- but a good deal of it (I'm not quite sure where Mr. Cates gets his 9% figure, but that's of no importance) is "lost" to the

Calculating Boiler Standby Heat Loss — Heating Help: …

Fire-tube boiler: Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

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.

coal boob furnace is changed to electric boiler

The AFUE rating for an all-electric furnace or boiler is between 95% and . The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice.

Direct and Indirect efficiency in boilers

Direct method is quick method for boiler efficiency calculation, In this method, Percentage of total heat output vs heat input is calculated to establish boiler performance. Boiler Efficiency = Heat output / Heat Input X 100. Or Boiler Efficiency = Q X (h2 – h1) / (q X GCV) X 100. Where Q = Qty of steam generated.

6/9/2001 · Dividing that into the input of 1,338,000 Btu/hr (the same as the gas-fired boiler), the boiler is consuming 9.7 gal./hr. At $1.40/gal., the operating cost is $13.58/hr. Piping losses are ignored. The electric boiler operates at full capacity, which for simplicity is assumed to supply process requirements and 3% losses in the short piping run between the boiler and the process.
