It reduces, the vapor in flue gas after effectively avoiding combustion heat-exchange encounters cold exhaust fume collecting hood component and generates condensed water, by flue gas
Middle sulfur oxide and nitrogen oxides form strong acid liquid after being dissolved in water, so that the components on heat exchanger and exhaust fume collecting hood component
It is corroded.
2. exhaust fume collecting hood component of the invention, the insulating layer is arranged on outer surface and/or the inner surface of the cover,
The structure of exhaust fume collecting hood component is simple, and facilitates the setting of the insulating layer.
3. exhaust fume collecting hood component of the invention, the heat preservation is provided between two layers adjacent of shell of at least one group
Layer, can be effectively prevented falling off for insulating layer, moreover, shell can play the role of protecting insulating layer, it is ensured that be pumped into from the external world
The inner wall of cold air and exhaust fume collecting hood component in burnt gas wall hanging furnace is effectively isolated.
4. the outside of the exhaust fume collecting hood component is arranged in fan assembly by burnt gas wall hanging furnace of the invention, it is possible to reduce collection
The volume of petticoat pipe component saves production cost, and the structure of burnt gas wall hanging furnace can be made more compact.
