Abstract

Kocioł wieżowy z oddzielnym kanałem kominowym i z regulowanym przepływem zawiera kilka płyt przegradzających kanał kominowy pomiędzy dwiema przeciwległymi ścianami bocznymi korpusu kotła, które dzielą wnętrze korpusu (6) kotła na kilka kanałów kominowych. Podczas wyprowadzania spalin poprzez różne kanały kominowe mogą one nagrzewać parę wodną wewnątrz przegrzewacza lub dogrzewacza. Ponadto realizowane jest przegrzewanie lub dogrzewanie, a w każdym z kanałów kominowych usytuowane jest kilka regulacyjnych przepustnic (21). Możliwe jest regulowanie temperatury przegrzanej pary wodnej z przegrzewacza oraz temperatury dogrzanej pary wodnej z dogrzewacza przez regulowanie natężenia przepływu spalin o wysokiej temperaturze w każdym kanale kominowym.The tower boiler with a separate chimney duct and regulated flow contains several plates separating the chimney duct between two opposite side walls of the boiler body, which divide the interior of the boiler body (6) into several chimney channels. When flue gas is vented through various chimney channels, they can heat the steam inside the superheater or additional heat. In addition, overheating or reheating is carried out, and in each of the chimney channels there are several regulating dampers (21). It is possible to regulate the temperature of superheated steam from the superheater and the temperature of the superheated steam from the additional heat by regulating the flow rate of high temperature flue gas in each chimney flue.
