Flue gas is observed: black smoke gas is arranged when lighting a fire, after burning is normal, can't see blackness of exhaustion substantially, and also do not have tangible blackness to change when coal.

Although it is not very strict that top twice experiment detects controlled condition, detection means neither be very advanced, basically can find out its beneficial effect:

The first, accomplished abundant burning basically.After entering normal combustion, with the naked eye can't see blackness of exhaustion, and behind coal, still do not observe the significant change of blackness, illustrate that burner hearth secondary benefit wind effect is obvious, combustion position is good.

The second, thermal efficiency height.Coal is very high in the temperature of the back flue gas that fully burns, and the maximum temperature of the stove actual discharge flue gas after the utility model enforcement is 142 ℃, and any product after this implements than prior art is all low, does not have very high thermal transition ability not accomplish this point.Certainly, because economics dictate, the utility model is not authority and is detected, and can not talk tactlessly concrete thermal efficiency numeral here.

Above-mentioned two all is to saving coal-fired providing powerful support for, do not accomplish abundant burning, can not economizing on coal; Do not have the very high thermal efficiency, can not economize on coal equally.Sum up experiment operation and two laboratory test results of 2002 heating seasons in year, can think the utility model 100m ²The heating stove of specification, area operation under dam, Zhangjiakou, each heating season consume Datong District's lump coal (calorific value 5800-6000 kilocalorie/kg) 2.5 tons, perhaps lower, compared with the prior art, accomplish that energy-conservation is complete surely feasible more than 40%.

As for the convenient function in the utility model especially intuitively, that sees sees, touch, do not give unnecessary details so here do not add.
