TLDR
In this paper, the authors compared the particle emissions from modern and old-type residential wood stoves and found that the fine particle maximum was displaced towards larger size during inefficient combustion, e.g. during start-up phase.Abstract:
The purpose of this work is to characterise particle emissions from pellets stoves and modern and old-type residential wood stoves. The mass concentration of particulate material in the hot flue gas was 19e82 mg/MJ, roughly the same for wood stoves and pellets stoves, but the old-type wood stoves tended to emit even higher quantities. Furthermore, during combustion of wood logs the considerably higher emission of organic gaseous carbon indicates an additional contribution to the emission from secondarily formed condensable organic particles.
The particle mass emitted was dominated by fine particles (<1 mm) in all cases. The fine particle maximum was displaced towards larger size during inefficient combustion, e.g. during the start-up phase. The number concentration of particles from wood stoves was 1.0$1014e6.0$1014 #/MJ, from pellets 3.0$1013e5.0$1013 #/MJ, and in all cases dominated by fine particles. Efficient combustion of pellets resulted mainly in inorganic particles, dominated by potassium sulphate and potassium chloride. Zinc, the second most frequent metal, and calcium showed the highest concentrations among the less volatile components.
The lowest concentration detected was for cadmium, about 105 times lower than for potassium.read more

TL;DR: It was estimated that 95,98, 98, 88, and 71% reductions in the total emissions of CO, OC, EC, PM, and PAHs could be achieved by replacing the raw biomass fuels combusted in traditional cooking stoves with pellets burned in modern pellet burners.

TL;DR: Particle surface area, number of ultrafine particles, bioavailable transition metals, polycyclic aromatic hydrocarbons (PAH), and other particle-bound organic compounds are suspected to be more important than particle mass in determining the effects of air pollution.

Emission characteristics of modern and old-type residential boilers fired with wood logs and wood pellets
TL;DR: In this paper, the authors compared the emissions from commercial residential boilers fired with wood logs and wood pellets, and found that the mass concentration of particles was 180 times larger in the worst old-type case (a water-cooled wood boiler without heat storage tank) compared to the best modern case (wood pellets).
