What chemical reaction occurs inside industrial steam boilers?

The main function of industrial steam boilers is to transform water at ambient temperature and pressure into water steam at a higher temperature and pressure, based on the energy of the fuel used. The type of fuel used during the combustion process and the conditions under which it is carried out determines that a series of chemical reactions occur. When a hydrocarbon is burned in industrial burners, its hydrogen combines with the oxygen in the air and produces water; the carbon combines with the oxygen in the air to form carbon dioxide and, in addition, energy is released in the form of heat. Some oxygen molecules combine with nitrogen molecules and result in nitrogen oxides (NOx) of the nitric oxide (NO) and nitrogen dioxide (NO2) types. To reduce its impact on the environment, ATTSU designs and manufactures fire-tube steam boilers with low NOx emissions (whose emission limit values ​​are less than 100 mg / Nm3) and capable of running on natural gas, LPG, diesel, fuel oil or biogas .

As more temperature has where combustion occurs, the greater the probability of NO and NO2 being generated. That is why ATTSU boilers are designed to lower the temperature in the combustion home, to generate a thermally more efficient and less polluting chemical reaction.
