In FEFU have developed a technology to increase the efficiency of power boilers
Technology, which increases the productivity of boilers and reduces the cost of thermal energy, was developed at the Far Eastern Federal University. As the press service of the FEFU informs, the installation of the cyclone-vortex prefurnace increases the efficiency factor by 6-8 percent, depending on the type of fuel used.
“The cyclone-vortex pre-furnace provides preliminary combustion of the fuel instead of the direct entry of the flame into the boiler, ensuring complete combustion. As a result, it is able to replace traditional burner technology. An important advantage is the ability to switch from gas to reserve liquid fuel without stopping the boiler, ”the university notes.
“The key feature is the presence of a pre-combustion chamber with a combined supply of air and gas, which makes it possible to effectively mix fuel and air in it at high thermal stresses and high flow turbulence. The most important thing is that they can be produced in Russia without ordering burners abroad, ”said Konstantin Shtym, Ph.D., Associate Professor of the Department of Heat Power Engineering and Heat Engineering of the Far Eastern Federal University.
The technological decision on the use of pre-furnace has already been implemented at 30 facilities of the Far East, including Vladivostok at CHP-1, Severnaya shopping center and industrial enterprises - Vladivostok Sea Fishing Port OJSC, Vostochny Port OJSC, Spaskcement OJSC, factory "Star". Installing a single high-power device reduces the cost of purchasing expensive automation and greatly simplifies the regulation and operation of the boiler.
