tube boilers, provided a 4% increase in the boiler e ciency. The second law e ciency of the boiler was improved from 24% to 25.2%. It was also shown that there was no need to use an excess fan for the ﬂue gas in the chimney because of the very low pressure drops in the new types of turbulator.

A word of caution. Post at, or on the boiler, where what turbulator goes in the boiler & what angle the handles should be set at. It's a pain to open a boiler to check lengths, locations, & angles. Full modulation will require some compromise. You will probably have to select turbulator lengths & locations based on your primary fuel. Good luck.
I have recently begun using Flow Simulation to analyze fire-tube boiler designs. For those not familiar, a fire-tube boiler is basically a shell-and-tube heat exchanger that uses hot combustion gasses in the tubes to heat water in the shell. The tubes are simple straight pipes, but they also have Brock turbulators (wavy strips of metal) in them.
Dispersal also causes the gas/fluid to transfer more of its energy to the tube wall. Function: Angular turbulators serve to improve heat transfer efficiency in firetube boilers and other similar heat exchange equipment. Material: Typically carbon steel, aluminized steel and various grades of stainless steel
This paper summarizes an experimental study of three popular "turbulator" inserts for fire tube boilers. An electrically heated flow facility was developed to deliver hot air to a water-cooled steel tube instrumented to derive sectional average heat transfer coefficients for four regions of the tube.

EXPERIMENTAL APPARATUS AND PROCEDURES A novel model of Fire-Tube boiler design is built up to operate a single hot gases tube in order to study the actual process
A fifth new turbulator, consisting of a truncated half-cylindrical surface and placed in tandem with flow direction, also periodically interrupted and transposed in the fire tube boilers, provided ...
Consider Installing Turbulators on Two- and Three-Pass Firetube Boilers Firetube Boilers The packaged firetube boiler is the most common boiler design used to provide heating or process steam in industrial and heavy commercial applications. The American Boiler Manufacturers Association (ABMA) surveyed sales of high-pressure [15- to
meet the turbulator Turbulators are designed to create and maintain turbulent flow and help to increase the tube-side heat transfer efficiency. A turbulator is a device which is inserted on the tube side of firetube boilers, shell & tube heat exchangers and other types of heat transfer equipment.
