Description

Изобретение относитс  к проблеме предотвращепи  коррозии и золового запоса поверхностей нагрева воздухоподогревател  котельных агрегатов, работающих на сернистых топливах .The invention relates to the problem of preventing corrosion and the ash of the heating surfaces of an air preheater of boiler units operating on sulfur fuels.

Известны различные способы воздухоподогревател  котлоагрегатов, работающих на сернистых топливах, от коррозии и отложений на поверхност х нагрева, нанрилгар , путем ввода присадок в топливо или дымовые газы, периодической промывкой поверхностей сжигапием топлива при ма,1ых избытках воздуха и т. п.Various methods are known for the air preheater of boiler units operating on sulfurous fuels, against corrosion and deposits on heating surfaces, naniligar, by introducing additives into fuel or flue gases, periodically flushing surfaces with fuel combustion, mA, excess air, etc.

Цель изобретени  - повысить эффективность защиты воздухоподогревател .The purpose of the invention is to increase the efficiency of air heater protection.

Это достигаетс  тем, что подлежащий нагреву воздух периодически направл ют к котлу в обвод воздухоподогревател , дл  прогрева теплообменной поверхности последнего дымовыми газами до температуры 270- 300° С. При такой температуре с теплообменной поверхности испар етс  осевша  па Heii серна  кислота.This is achieved by the fact that the air to be heated is periodically directed to the boiler in the bypass of the air preheater, to heat the heat exchange surface of the latter with flue gases to a temperature of 270-300 ° C. At this temperature, the Heii sulfuric acid vaporized from the heat exchange surface evaporates.

Па чертеже схемат1:чески изображен регенеративный воздухоподогреватель котлоагрегата дл  осуществлени  предложенного снособа с лини ми воздуха и дымовых газов. Па воздуилной предусмотрен обвод, через который одпп раз в сутки на 10-20 мин воздух направл етс  в котел, мппу  воздухоподогреватель . Дл  этого на линии подачи воздуха закрывают шпбер 1 н открывают нибер 2. При отсутствии холодного воздуха дымовые газы прогревают поверхность воздухоподогревател  3 до 270-300° С.PA drawing schematic 1: a regenerative air preheater of a boiler unit is shown for implementing the proposed procedure with air and flue gas lines. A bypass is provided for bypassing, through which air is sent once a day for 10–20 minutes to the boiler, the air heater. To do this, on the air supply line they close the shield 1 n. Open the niber 2. In the absence of cold air, flue gases heat the surface of the air preheater 3 to 270-300 ° C.
