The boiler is better able to respond to large loads as the ‘low fire’ position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on ‘low fire’, it can immediately respond by increasing the firing rate to ‘high fire’, for example the purge cycle can be omitted.

Author: Michele Tomas The FTXL boiler is the new 98% efficiency standard in fire tube technology, and it puts remote connectivity at your fingertips. The FTXL boiler also has a compact footprint of just 6.2 sq. ft. 5 Models from 399,999 to 850,000 Btu/hr Up to 98% Thermal Efficiency

Cochran boiler fire tube. The more efficient fire tube boiler has many tubes of small diameter passing through the water space of shell. Retarders are often fitted in these tubes, which increase the stay time of flue gases, this increasing the heating surface through which (fuels energy) heat is transfer to the water.

File Size: 296KB Jun 05, 2018· In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers.

[PDF]key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

Feb 19, 2015· The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam.

Author: Tim Seberger FTV Series. The FTV is a high-efficiency, wall-hung boiler equipped with a vertical fire tube heat exchanger made of industry proven 439 stainless steel.

The combustion efficiency of a boiler is the indication of burner’s ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the …

Apr 23, 2016· If we talk about the efficiency then the overall efficiency of fire tube boilers is about 75%. The direction of the water circulation is not well defined i.e. a definite path is not provided for the circulation of water.

The efficiency of the fire tube boiler is less as compared to the water tube boiler. The efficiency of the water tube boiler is more. 14. The maintenance of this boiler is costly.
