Description
(54)СПОСОБ РАБОТЫ КОТЕЛЬНОГО АГРЕГАТА(54) METHOD OF WORK OF BOILER UNIT
Изобретение относитс к энергетике и может быть использовано при сжигании шлакующихс бурых углей в котельных агрегатах. Известен способ работы котельного агрегата путем утилизации тепла топочных газов дл нагрев.а воздуха,последующего смешени части охлажденных газов с холодным воздухом и подачи полученной смеси дл сжигани топлива р. Недостатком известного способа вл етс низка эффективность, св зан на с шлакованием поверхностей нагрева и высокими затратами на собственны ну ады. Цель изобретени - повышение, эффективности путем уменьшени шлакоаани поверхностей нагрева при сжигании шлакухицихс бурых углей и сокращени затрат на собственные нужды. Указанна цель достигаетс тем, что на смешение с холодным воздухом отбирают 20-35% от общего весового Количества охлажденных топочных газов, а часть смеси перед подачей на сжигание, отдел ют и используют дл предварительной перед сжиганием сушки топлива. Кроме того, дл сушки топлива используют от общего весового количества полученной смеси. На чертеже изображена схема котельного агрегата, осуществл юща предлагаемый способ. Котельный агрегат содержит топку 1 с горелками 2, подключенными к системе 3 подготовки топлива, В газоходе 4 котельного агрегата установлен воздухоподогреватель 5, подключенный на выходе по воздуху трубопроводами 6 и 7 к горелкам 2 и системе 3 подготовки топлива, а по дымовым газам 7 к золоуловителю 8 и дымососу 9 каналом 10, который за дымососом 9 сообщен трубопроводом 11 с каналом 12 подачи воздуха вентил тором 13. При работе котельного агрегата топочные газы проход т через воздухоThe invention relates to energy and can be used in the combustion of slagging brown coal in boiler units. A known method of operating a boiler unit is by utilizing heat from the flue gases to heat the air, then mixing a portion of the cooled gases with cold air and feeding the resulting mixture to burn the fuel p. The disadvantage of this method is low efficiency, which is associated with the slagging of the heating surfaces and high costs for its own costs. The purpose of the invention is to increase the efficiency by reducing slag-like heating surfaces when burning slagurite brown coal and reducing the cost of own needs. This goal is achieved by taking 20–35% of the total weight of the cooled flue gases for mixing with cold air, and part of the mixture, before being fed to the combustion, is separated and used to pre-burn the fuel before burning. In addition, the total weight of the mixture obtained is used to dry the fuel. The drawing shows a diagram of the boiler unit, carrying out the proposed method. The boiler unit contains a furnace 1 with burners 2 connected to the fuel preparation system 3, an air heater 5 is installed in the gas boiler 4 of the boiler unit; 8 and the exhauster 9 by the channel 10, which behind the exhauster 9 is connected by a pipe 11 to the air supply channel 12 by the fan 13. When the boiler unit is operating, the flue gases pass through the air
