Industrial furnace high-efficiency atomizer burner based on high-viscosity biomass fuel

Abstract

The invention relates to an industrial furnace high-efficiency atomizer burner based on high-viscosity biomass fuel, and belongs to the technical field of energy and environments. In the industrial furnace high-efficiency atomizer burner, a fuel channel, a high-pressure nitrogen channel and a high-pressure oxygen channel are three layers of cavities which are concentric from inside to outside, one end of the fuel channel is provided with a fuel inlet, the other end of the fuel channel is provided with a fuel nozzle, the top of one end of the high-pressure nitrogen channel is provided with a nitrogen inlet, and the end part of the other end of the high-pressure nitrogen channel is provided with a first-grade nitrogen atomizing converging-diverging plate; and the top of one end of the high-pressure oxygen channel is provided with an oxygen inlet, the other end of the high-pressure oxygen channel is provided with a second-grade oxygen atomizing converging-diverging plate, a mounting flange connected with an industrial furnace is arranged on the high-pressure oxygen channel, and the high-pressure oxygen channel is provided with an electronic spark electrode penetrating through the high-pressure oxygen channel. According to the industrial furnace high-efficiency atomizer burner based on the high-viscosity biomass fuel, waste nitrogen after oxygen generating is utilized to serve as an auxiliary atomizing gas medium, after first-grade atomizing is conducted by utilizing the nitrogen, a non-burning isolation area which is about 5 cm is formed, it is ensured that a fuel pocket cannot burn at an outlet of the nozzle, and therefore the problems that nozzle outlet sintering and carbon depositing are solved.

Description

technical field [0001] The invention relates to an industrial furnace high-efficiency atomization burner based on high-viscosity biomass fuel oil, which belongs to the technical field of energy and environment. Background technique [0002] In the actual production of iron and steel smelting, glass furnace smelting, etc., a large amount of 0# diesel oil and heavy oil are required to be burned. However, the current energy situation, the depletion of fossil energy, and the discharge of various harmful pollutants after combustion are very serious facts. , Bringing higher production and environmental protection costs to enterprises, there is an urgent need to seek alternative energy sources. Biomass fuel, as an important supplement or even an alternative fuel to petrochemical fuel, has rapidly entered people's field of vision in recent years. Biomass fuel has great development potential, and it is of great practical significance to use biomass fuel in industrial furnaces to repl...
