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.

Conversion of heat transfer coefficient
Hour (kcal/ SQM. H) =1.16279 watts/SQM (w/ SQM)
1 kcal/(m.. ℃) [1 kcal/(m.h. ℃)) = 1.16279 w/(m. Kelvin) w/(m2. K)
1 British thermal unit /(ft. 2. H.℉) [Btu/(ft2.h.℉)] =5.67826 w/ (m. Kelvin) [(w/ m2.k)]
1 m2 h.℃/kcal (m2.h.℃/kcal) =0.86000 m2. Kelvin/watt (m2.k /W)

The "medium pressure air-tumber" atomized burner developed for burning straw oil has good applicability not only to straw oil, but also to bio-oil and petroleum oil.This kind of burners can be used to realize the normal combustion of heavy asphaltene and colloid and inferior oil with high density.
Integrated control system is that we proposed earlier today's more advanced control mode, is widely used in Europe and the us some dimensions industry in our country and demanding enterprises choose this control concept, its core idea is to put the boiler and burner control together unified programming, making accurate digital control, this control model to avoid the original control of shortcomings, such as: scattered, incompatible, multipoint multiple handling, economic problems.
Its advantages are obvious:
Software compatibility optimization, electronic control uniformity, greatly improve the control accuracy, energy saving
Design and manufacture consistency, safety and reliability and production cost savings
Single human-computer interface dialogue
Operating system intuition
Improve maneuverability and safety
Single professional debugging, to ensure safety and efficiency
Continuity of one-stop after-sales service, greatly improve the work efficiency, reduce the service cost for users
One-click accessories, software and supply upgrades are guaranteed
Enough about how to solve the trouble of burner
New energy enterprises are not only the direct beneficiaries of clean energy consumption, but also important participants, bearing important responsibilities.Participate in the spot power market and auxiliary service market, improve the system dispatching ability in a market-oriented way, and promote the consumption of clean energy.
