A burner is a device for ejecting a mixture of fuel and air in a certain way.Burners are classified into industrial burners, burners, civil burners and special burners according to their types and application fields.Multi-purpose stainless steel or titanium metal corrosion resistant, high temperature resistant materials made.The role of the burner is to atomize the sample through flame combustion.The atomized test solution enters the burner and, under the action of flame temperature and atmosphere, goes through drying, melting, evaporation, dissociation and other processes to produce a large number of ground state atoms and some excited state atoms, ions and molecules.A well-designed burner should have the characteristics of high atomization efficiency, low noise and stable flame, so as to ensure high absorption sensitivity and precision of measurement.Gap burners are commonly used in atomic absorption spectrometry to generate atomic vapor.According to the different types of gas and auxiliary gas, the length and width of the gap of the burner are different. Generally, applicable gas and auxiliary gas are marked on the burner.
At present, the traditional fossil fuels such as coal, oil and natural gas have brought many problems such as environmental pollution and greenhouse effect to human beings.
There are many petrochemical and chlorine-alkali enterprises in China. Many petrochemical and methanol hydrogen production enterprises will produce a large amount of industrial tail gas with hydrogen content of 50%~60% or even more than 90%, which is called hydrogen-rich tail gas.
Hydrogen - rich tail gas is flammable, explosive, large, difficult to transport, and contains certain harmful organic matter, direct emission of environmental pollution;Treatment and utilization of hydrogen-rich tail gas is not only conducive to environmental protection, but also can save energy and reduce costs, thus improving the economic benefits of enterprises.
Many projects to increase the flue gas external circulation, according to the on-site reaction, the flue gas recirculated condensed water is a lot, in winter, the wind duct will even freeze.This is because the hot and humid smoke and combustion fresh air mixed, mixed steam beyond the mixed air temperature of the saturated humidity, the excess steam formed condensed water.CO2 in the flue gas will dissolve in the condensed water. If the acidic condensed water enters the burner or fan, it will easily corrode the components of the burner or fan.Measures must be taken to prevent condensation from entering the burner or fan.Add heat preservation for recirculating smoke pipe, reserve condensate water outlet, fresh air and preheat.
Condensate water discharge device shall be set at the lowest point of each section of the circulation flue. If there is a mixing bellows, condensate water discharge device shall be set on the mixing bellows. If necessary, condensate water discharge device may also be set on the fan.Condensate water discharge device recommended made of water seal type, the highest point of the water seal lower than the lowest point of the flue gas pipeline, for the convenience of condensate water discharge.
