Tangent circle burner nozzle tube panel assembly frame

Abstract

The invention relates to a tangent circle burner nozzle tube panel assembly frame. The tangent circle burner nozzle tube panel assembly frame comprises a bottom framework, a horizontal supporting beam, a first inclined beam and a second inclined beam. One end of the first inclined beam is fixedly connected with the bottom framework, and the other end of the first inclined beam is fixedly connected with the horizontal supporting beam. One end of the second inclined beam is fixedly connected with the bottom framework, and the other end of the second inclined beam is fixedly connected with the horizontal supporting beam. The tangent circle burner nozzle tube panel assembly frame further comprises first longitudinal beams and second longitudinal beams, the first longitudinal beams and the second longitudinal beams are kept vertical and are fixedly connected with the bottom framework; a first positioning beam is fixedly connected with the first longitudinal beams, and a second positioning beam is fixedly connected with the second longitudinal beams; a first tube end positioning beam is fixed to the first inclined beam, and a second tube end positioning beam is fixed to the second inclined beam; a first horizontal reference beam and a second horizontal reference beam are both kept horizontal and fixedly connected with the two ends of the horizontal supporting beam respectively. The tangent circle burner nozzle tube panel assembly frame improves the assembly precision and the assembly efficiency of a burner nozzle tube panel.

Description

technical field [0001] The invention relates to a tooling device for boiler production, in particular to a nozzle tube panel assembly frame for a tangential burner. Background technique [0002] Boiler refers to the equipment that uses various fuels, electricity or other energy sources to heat the liquid contained in it to a certain parameter and output heat energy to the outside. Boilers are divided into subcritical boilers, supercritical boilers, and ultra-supercritical boilers. Due to supercritical Boilers and ultra-supercritical boilers have significant energy-saving and environmental-improving effects. Therefore, the future development and construction of boilers will also mainly develop towards high-efficiency and high-parameter supercritical boilers and ultra-supercritical boilers; [0003] However, the assembly of burner nozzle tube panels in supercritical boilers and ultra-supercritical boilers has always been a difficult problem for those skilled in the art.

Problems solved by technology

[0003] However, the assembly of burner nozzle tube panels in supercritical boilers and ultra-supercritical boilers has always been a difficult problem for those skilled in the art. Because the burner nozzle tube panels used in tangential combustion boilers have complex spatial structures of the tube panels, the tube panels Due to the large number of tube panels, various sealing forms of the tube panel, large welding workload, large number of pipe elbows, and difficulty in controlling the space size, it is difficult to ensure the assembly accuracy of the burner nozzle tube panel manufacturing process; therefore, it is difficult to design a tube panel that can It is urgently needed by those skilled in the art to complete the assembly of multiple nozzles with high efficiency and high precision.
