taste intensity may reach the same value as the odour in- tensity The smellable and tastable emissions are sensed as being unpleasant all the more, the less diluted the exhaust gas gets inhaled The emissions produced when operating on high excess of air are sensed as the most leasant ones among all exhaust gas samples Operating the unpleasant Even though combustion becomes more incomplete on higher deficienc of air, the emissions produced through it cause more pleasantsensationsthan on only low deiciency of air On verey high deficiency of air, finally, the combution odours are clearly sensed as the most unpleasant ones On low deficiency of air, the concentrations of the volatile hydrocarbons (benzene, toluene) rise somewhat, with further reduction of air the concentration of these substances still rises and, additionally, substances with hi boiling points like naphtaline, can be found On very great deficiency of air, therearevoltatfeand higher organicsubstances in increased concentra- tions burner down to condition low deficiency of air, the combustion odours become more Vaporizing Heating Oil Burner Altogether, six series of measurementswith different load stages- each time with and without red-hot metal inset - were carried out. In the course of series of measurements, the content of oxygen, carbon dioxide and carbon monoxide, the sum of the hydrocarbon concentration in the exhaust gas, and different temperatures were continuously measured. At the same time, variable samplings were taken to establish the smoke spot number and different mono- aromatic and polyc clicaromatic hydrocarbons. As result of the investigations, operating the furnace in the me& load range proved to be most favorable with regard to quantity and dangerous potential of the emitted compounds.The emission of polycyclicaromatic hydrocar- bons in this case, too, was lower than with maximum or low load. With maximum load, the lowest content of low boiling aromatics and
