Description
(54) СПОСОБ РАБОТЫ КОТЕЛЬНОГО АГРЕГАТА(54) METHOD OF WORK OF BOILER UNIT
Изобретение относитс к энергетике и может быть использовано в котельных агрегатах злектростанции.The invention relates to power engineering and can be used in power plants of a power plant.
Известен способ работы котельного агрегата с топкой и двухступенчатым воздухоподогревателем путем последовательного пропускани воздуха через холодную и гор чую ступени воздухоподогревател с одновременным перепусканием мимо последней части дымовых газов 1 .A known method of operating a boiler unit with a firebox and a two-stage air preheater is by successively passing air through the cold and hot stages of the air preheater while simultaneously passing the last part of the flue gases past 1.
Недостатком данного способа вл етс невозможность регулировани температуры воздуха на выходе из гор чей ступени воздухоподогревател при изменении влажности топлива или нагрузки котельного агрегата без снижени его экономичности.The disadvantage of this method is that it is impossible to control the air temperature at the exit from the hot stage of the air preheater when the moisture content of the fuel or the load of the boiler unit changes without reducing its efficiency.
Цель изобретени - обеспечение регулировани температуры воздуха.The purpose of the invention is to regulate the temperature of the air.
Указанна цель достигаетс тем, что часть воздуха, выход щего из холодной ступени, подают в топку котлоагрегата.This goal is achieved in that part of the air coming out of the cold stage is fed to the boiler furnace.
На чертеже изображен котельный агрегат, реализующий предлагаемый способ.The drawing shows the boiler unit that implements the proposed method.

Котельный афегат содержит топку 1 с газоходом 2, снабженным перегородкой 3, и воздухоподогреватель с гор чей 4 и холодной 5 ступен ми. Перед гор чей ступенью 4 установлена задвижка 6.The boiler compartment contains a furnace 1 with a flue 2 equipped with a partition 3 and an air heater with hot 4 and cold 5 steps. In front of the hot stage 4, the valve 6 is installed.
При работе котельного агрегата дымовые газы из топки 1 поступают в газоход 2, где раздел ютс на два потока, один из которых проходит гор чую ступень 4, на выходе из которой объедин етс с другим потоком и следует через холодную ступень 5. Часть воздуха на выходе из холодной ступени 5 отбираетс и направл етс в топку 1, остальной воздух, подогретый в гор гей ступени 4, используетс в системе пылеприготовлени либо дл транспортировки готовой пыли. Регулирование температуры воздуха в гор чей ступени 4 осуществл етс при помощи задвижки 6.During operation of the boiler unit, the flue gases from the furnace 1 enter the duct 2, where they are divided into two streams, one of which passes through the hot stage 4, at the outlet of which it is combined with another stream and flows through the cold stage 5. Part of the air at the outlet from the cold stage 5 is taken and sent to the furnace 1, the rest of the air heated in the hot stage 4 is used in the pulverization system or for transporting the finished dust. The regulation of the air temperature in the hot stage 4 is carried out by means of the valve 6.
