Natural gas and hydrogen mixed burner

Abstract

The invention discloses a natural gas and hydrogen mixed burner, and relates to the field of natural gas and hydrogen mixing. The natural gas and hydrogen mixed burner comprises a treatment main box, a control panel is embedded in the top surface of the treatment main box, fixing plates are symmetrically and horizontally welded to the two side edges of the treatment main box, and a fire observation hole is formed in one side edge of the treatment main box. One side edge of the treatment main box is in bolted connection with an electric igniter, one side edge of the treatment main box is in bolted connection with a flame ion detection flameout protection device, one side edge of the treatment main box is in bolted connection with a small air blower, and one side edge of the treatment main box is vertically inserted with a natural gas inlet pipe joint. A natural gas valve is arranged on the outer side edge of the natural gas inlet pipe joint, and the outer side edge of the natural gas inlet pipe joint is in threaded connection with a natural gas flow meter. According to the natural gas and hydrogen mixed burner, the configuration of a mixed gas storage tank is reduced, steel is saved, the risk of combustion explosion is reduced, meanwhile, the mixed combustion structure meets the national standard requirement, and the combustion is more environment-friendly and clean.

Description

technical field [0001] The invention relates to the technical field of natural gas and hydrogen mixing, in particular to a natural gas and hydrogen mixing burner. Background technique [0002] Hydrogen energy is a clean and environmentally friendly fuel that can replace petroleum. The calorific value of hydrogen energy gas after combustion is higher than that of petrochemical fuels. Hydrogen gas does not produce pollutants after combustion, and all emission indicators meet or exceed national environmental protection requirements. It is an ideal combustion gas. Natural gas is a low-carbon hydrocarbon mixture mainly composed of methane. It can be divided into dry gas and wet gas according to its composition. Generally, natural gas with a methane content higher than 90% is called dry gas, and gas with a methane content lower than 90% is called wet gas. There is a certain amount of ethane, propane, butane and above hydrocarbons in the gas, which can be mixed and burned with hyd...

Problems solved by technology

[0004] The purpose of the present invention is to provide a natural gas and hydrogen mixed burner, to solve the above-mentioned background technology for the current mixed combustion process of mixing a small amount of hydrogen into natural gas, all adopting a gas storage tank to reconcile the proportional combustion , thus increasing the risk of explosion. At the same time, a large amount of steel and other materials need to be used to make settings during production, which greatly wastes materials and makes it unfavorable for the current utilization of mixed combustion energy in hydrogen and natural gas.
