Čia aš nesiginčysiu, ir neginsiu mokslo galvų, kurie gavo daug pinigų iš valstybės už tokio rezultato gavimo. Google įvedus užklausą "CO emission secondary combustion" išmes institutų išvadų, sprendimų būdų su 200 lapų kiekviename.
Duodu anglišką ištraukos kopiją iš vieno tokių dokumentų:
To decrease PM and CO emissions from wood stoves, combustion efficiency must increase.
Both catalytic and noncatalytic control techniques increase efficiency and decrease emissions.
Catalytic combustors reduce emissions by using a ceramic catalyst coated with a noble metal
(e. g., palladium or platinum) which allows organics and other combustibles to burn at temperatures
much lower than required in a noncatalytic firebox.
Older, noncatalytic wood stoves reduce emissions by directing unburned hydrocarbons (HCs)
and CO into a secondary chamber, where mixing with fresh, preheated makeup air enhances further
combustion. Current noncatalytic wood stoves inject fresh secondary air into the top of the primary
combustion chamber, allowing ignition of the HCs. Multiple air channels, some with their own
controls, coupled with baffles which trap and retain heat in the top of the firebox facilitate this
combustion.
Emission factors and their ratings for wood combustion in residential wood stoves, pellet
stoves, and masonry heaters are presented in Tables 1.10-1, 1.10-2, 1.10-3, 1.10-4, 1.10-5, 1.10-6, and
1.10-7. Tables in this section present emission factors on a weight basis (lb/ton). To convert to an
energy basis (lb/MMBtu), divide by a heating value of 17.3 MMBtu/ton. The analysis leading to the
revision of these emission factors is contained in the emission factor documentation.

Kross, o tu mokykloj anglu ar prancuzu mokinaisi ? Antrinis degimas neturi nieko bendro su "kiaurom" krosnelem
todel ir prasiau konkretaus dokumento, kur parasyta - "negalima visiskai uzdaryti oro padavimo" nes tai tik pasiteisinimas "kiauru" krosneliu gamintojams. Stai *** turi tokia pacia problema - patikejo marketinginiais makaronais ir ... 
uzdaro oro padavima, o krosnele vis tiek dega, nes siurbia ora pro visas skyles, tarpines ir kitus nesandarumus. Antrinis, tretinis degimas ir visi kiti navarotai - tai tik geresniam ir svaresniam CO ir kietuju daleliu sudeginimui, o ne krosneles sandaraumui ar skyletumui pagristi.Todel mano giliu isitikinimu - krosnele kuri uzdarius oro padavima vis tiek dega - yra kiauras kibiras, tik uz didene kaina ir kitokio dizaino.
