Before reconstruction BKZ-210-140FD boilers of OJSC “Zapadno-Sibirskaya TPP” were equipped with six dust, gas and oil burners of a snail-type, set by three at the side walls of the furnace under triangle scheme with its vertex down. By that, two top burners were installed at a mark of 10,7 m , and the lower burner –at a mark of 9.8 m.
