Boiler circulation mode refers to the steam flow mode in boiler evaporation system, which can be divided into natural circulation, auxiliary circulation, DIRECT current and composite circulation.
Flue gas purification and ash treatment
The boiler flue gas contains dust (including fly ash and black carbon), sulfur and nitrogen oxides are all substances that pollute the atmosphere, and its emission index may reach several times to dozens of times of the environmental protection regulations when it is not purified.
Measures to control the discharge of these substances include pre-combustion treatment, improved combustion technology, dust removal, desulfurization and denitration.
High chimneys can only reduce the concentration of pollutants in the atmosphere near the chimneys
