Description
Technical field
The utility model relates to wall-hung boiler field, particularly a kind of smoke evacuation system of burnt gas wall hanging furnace.
Background technology
Blower fan is as the critical piece of wall-hung boiler, its effect is that the waste gas that burning is produced is forced to discharge, to in air intake combustion chamber, make combustion gas normal combustion, and whether completely the size of wind speed has influence on burning and whether heat exchange is abundant simultaneously, directly have influence on the thermal efficiency of wall-hung boiler.At present, burnt gas wall hanging furnace detects the working order of blower fan mostly by blast switch, and traditional blast switch transmits the work that a switching signal is controlled burnt gas wall hanging furnace when only pressure reduction surpasses fixed value again, cause and cannot make feedback to the concrete variation of wind flow, thereby cannot avoid minimizing because of wind flow to cause burning insufficient, and too much cause a large amount of losses of heat because of wind flow.
Utility model content
The utility model has been designed and developed a kind of smoke evacuation system of burnt gas wall hanging furnace, the problem of the loss of the insufficient or amount of heat that too much causes because of wind flow of burning that the size that the utility model can be measured wind flow has avoided the minimizing because of wind flow to cause, and can according to the burning load situation of combustion chamber, adjust the rotating speed of blower fan, so there is the function of energy-saving and emission-reduction.
The technical scheme that the utility model provides is:
A smoke evacuation system for burnt gas wall hanging furnace, comprising:
Combustion chamber;
Flue, its one end is connected with described combustion chamber, the other end is connected with outdoor, described flue comprises interior conduit and Outer Tube, between described interior conduit and Outer Tube, form air duct, outdoor air enters in described combustion chamber by described air duct, and combustion product gases drains into outdoor by interior conduit;
Blower fan, the top that it is arranged on described combustion chamber, the inner tube road junction that is positioned at the flue end being connected with described combustion chamber is located;
