Abstract
In order to prevent air pollution, gases evaporated from articles preheated in a preheating chamber of a continuous furnace are automatically and compulsorily sucked into a high-temperature chamber annexed to the preheating chamber by creating a negative pressure working in the high-temperature chamber. After the gases have been completely oxidized and decomposed in the high-temperature chamber at a high temperature and under an excess of oxygen, they are exhausted outside of the furnace via an exhaust-pipe extending through the preheating chamber, so that they join to heat the preheating chamber.
