Oct 26, 2020 · Fire Tube Boilers and Turndown Limits. Fire tube design hydronic boilers do not have the velocity limitations imposed by water in the tube designs. The flow rate can be as high as the maximum caused by mechanical and pressure drop limits. The low flow is only limited by the need to remove the excess heat after the burner shuts down.

The double fire-tube boiler with water-cooled reversal chamber and burner penetration has a capacity of 70 t/h and pressures of 0.5 to 40 bar (g). As hot water boilers, the capacity is between 0,5 and 44 MW. The design temperature for the hot water boilers can be up to 200 ºC. To achieve better efficiency, an economiser can be installed.

The Fire Tube Boiler is manufactured in Massachusetts with the highest quality materials. The 316L stainless steel fire tube heat exchanger is more resistant to corrosion in comparison to typical copper or aluminum heat exchangers. 316L stainless steel lasts longer and is virtually maintenance free, while also facilitating the transfer of heat more efficiently.

Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.

Jan 09, 2019 · In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures. As a guideline, competitive fire tube boilers for steam speeds up to 12,000 kg / hour with pressures up to 18

The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer a far greater heating surface area for the
