Abstract

The invention discloses a low-NO x A gas burner is used to solve the problem that the amount of nitrogen oxides produced in the combustion process of natural gas is difficult to meet the ultra-low nitrogen emission requirements; the burner includes an air supply pipeline and a gas supply pipeline. The primary air duct, the secondary air diverter ring, the gas diverter ring, and the air cyclone are arranged coaxially; the air cyclone is sleeved and installed in the downstream of the primary air duct, and there is a gap between the air cyclone and the primary air duct; The outlet of the gas distribution ring is connected with a central gas pipe and a circumferential gas pipe. The end of the central gas pipe extends to the center of the air cyclone, and the end of the circumferential gas pipe passes through the gap between the air cyclone and the primary air pipe. Bend radially inward or outward at 90°, the ends of the central gas pipe and the circumferential gas pipe are blocked, and gas injection holes are set on the side walls; through coupling staged combustion, swirl combustion and diffused flow combustion technologies, the gas low NO x burning purpose.

Description

technical field [0001] The invention belongs to the technical field of thermal energy and power engineering, and relates to a low NO x Combustors, especially a low NO x gas burner. Background technique [0002] With the green transformation of the energy structure and the proposal of carbon neutrality goals, the consumption of natural gas continues to increase. Although natural gas is a clean energy, the nitrogen oxides generated during the combustion of natural gas will cause harm to the atmospheric ecological environment and people's health. Therefore, reducing the amount of nitrogen oxides generated in natural gas combustion has become a key issue that needs to be solved urgently in the process of natural gas combustion and utilization. Natural gas low-nitrogen combustion technology mainly focuses on how to reduce combustion temperature and thermal NO x At the same time, consider strengthening the rapid and uniform mixing of natural gas and air in the early stage to r...
