At oil- and gas-fired boilers with bottom eddy burners a problem relating to reliable operation of furnace screens at oil combustion, has been worked out. At the same time a problem on ensuring a reliable operation of metal of screens and convective superheater packages at gas combustion, became sharper. In addition, specific emissions of nitrogen oxides are several times higher than the standard values at oil combustion and, especially, at natural gas combustion.
