Abstract

Kocioł wieżowy wyposażony jest w główny przegrzewacz międzystopniowy i pomocniczy przegrzewacz międzystopniowy. Kocioł posiada niskotemperaturowy przegrzewacz pary i wysokotemperaturowy przegrzewacz pary, zaś proces wykorzystywany w głównym systemie parowym obejmuje następujące etapy: woda zasilająca wprowadzana jest do przedniego przepływowego podgrzewacza wody i tylnego przepływowego podgrzewacza wody (10), które rozmieszczone są równolegle względem siebie, woda pochodząca z wylotów przepływowych podgrzewaczy wody wprowadzana jest do chłodzonych wodą ścian (1) od strony dolnej części paleniska; wyloty chłodzonych wodą ścian połączone są z oddzielaczem (19), zaś para pochodząca z wylotu oddzielacza wprowadzana jest kolejno do niskotemperaturowego przegrzewacza pary i wysokotemperaturowego przegrzewacza pary (31).Patrząc w kierunku przepływu pary z obszaru o niskiej temperaturze do obszaru o wysokiej temperaturze, główny przegrzewacz międzystopniowy zawiera kolejno główny niskotemperaturowy przegrzewacz międzystopniowy (11) i główny wysokotemperaturowy przegrzewacz międzystopniowy, zaś pomocniczy przegrzewacz międzystopniowy zawiera kolejno pomocniczy niskotemperaturowy przegrzewacz międzystopniowy (12) i pomocniczy wysokotemperaturowy przegrzewacz międzystopniowy, gdzie główny przegrzewacz międzystopniowy i pomocniczy przegrzewacz międzystopniowy umieszczone są równolegle względem siebie w pionowym kanale spalinowym. The tower boiler is equipped with a main intercooler and an auxiliary intercooler. The boiler has a low temperature steam superheater and a high temperature steam superheater, and the process used in the main steam system includes the following steps: feed water is introduced into the front flow water heater and the rear flow water heater (10) which are arranged parallel to each other, water from the outlets instantaneous water heaters are introduced to water-cooled walls (1) from the bottom side of the furnace; the outlets of the water cooled walls are connected to the separator (19), and the steam coming from the outlet of the separator is introduced successively to the low temperature steam superheater and the high temperature steam superheater (31). The intercooler comprises successively a main low temperature intercooler (11) and a main high temperature intercooler, and the auxiliary reheater successively comprises an auxiliary low temperature intercooler (12) and an auxiliary high temperature intercooler, where the main intercooler and auxiliary superheater are located in parallel with each other. vertical flue gas duct.
