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.
The frequent occurrence of major climate disasters in the world in 2012 is the result of mankind's increasingly profound understanding of the destructive effects of climate warming.Climate warming is caused by the uncontrolled use of fossil fuels by human beings, which increases the carbon dioxide content in the atmosphere year by year, strengthens the greenhouse effect and destroys the laws of atmospheric circulation.Now the world is exploring new energy sources to replace fossil energy and scientific ways of industrial production and application. Solar energy, wind energy and nuclear energy have been developed and utilized practically.However, the development and utilization technology of biomass industrial energy is just beginning and will last a long time.
Biomass energy comes from solar energy and CO2 in the atmosphere. Plants absorb CO2 and sunlight in the atmosphere during their growth and synthesize various organic substances, some of which are used by animals to form animal energy.When the organisms and their products are burned, they release energy and at the same time release the absorbed CO2 into the atmosphere in equal amount.For the global atmosphere system, the CO2 increment of this energy use to the atmosphere is zero, which is called carbon zero emission.There is a huge amount of biomass fuel on earth. If fully utilized, it will play an important role in reducing CO2 emissions.The development, research and utilization of solid, liquid and gaseous fuels of plant straw are under development.
The air supply system is an important component of the combustion system. The evenness, stability and width of the air volume directly affect the combustion effect and adjusting width.
The air supply system is composed of air inlet net cover, motor, bellows, wind blade, soft coupler, air inlet muffler (alternative), full cover muffler (alternative) and avoidance support (alternative).

From the perspective of heat transfer calculation, the measures to reduce the smoke exhaust temperature are analyzed from the following aspects: increasing the heat exchange surface, improving the heat exchange efficiency of the heating surface, improving the heat exchange temperature difference by using a lower temperature source, and reducing the influence of corrosion on the heat exchange efficiency.As gas boiler host first meet the low nitrogen flame furnace volume and size requirements, the second host of convection heating surface is a main export in order to reduce the smoke temperature, general control in 150 ~ 250 ° C, in order to avoid the smoke temperature increases along with the flue design difficulty of heat preservation, high smoking temperature is too low will cause corrosion in furnace convection heating surface forming wall condensation, therefore, furnace domestic demand to design proper heating surface, the physical dimension more representative chamber size.Increasing the heat exchange surface should mainly consider increasing the heat exchange area of the equipment in the rear of the boiler, which is more favorable for rapidly reducing the exhaust temperature.The second is to have a lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, corrosion resistant materials can be used to improve its service life.The new structure of efficient heat exchange mainly adopts the form of staggered tube arrangement, efficient heat exchange finned tube, plate heat exchanger, etc., to increase the flue gas disturbance and contact surface, reduce the heat resistance of flue gas stratification, and improve the heat exchange efficiency of medium and flue gas.
Clean energy is an important force in energy transformation and development. Active consumption of clean energy is a powerful starting point for implementing the revolutionary strategy of energy production and consumption, building a clean, low nitrogen, safe and efficient modern energy system, and a key link for accelerating the construction of ecological civilization and realizing a beautiful China.
In recent years, China's clean energy industry has grown and grown, and its industrial scale and technical equipment level have reached a new level, making outstanding contributions to easing the constraints on energy and resources and the pressure on the ecological environment.But at the same time, the unbalanced and insufficient development of clean energy is also increasingly prominent. In particular, the consumption of clean energy is prominent, which has seriously restricted the healthy and sustainable development of the power industry.
