Abstract: A waste containing organic solids is fed into a boiler after it has been subjected to a hydrothermal reaction treatment in the presence of water. A slurry containing the waste is held under high-temperature and high-pressure conditions to cause a hydrothermal reaction such that an acidic slurry is formed during part of or throughout the process of the hydrothermal reaction. Thereby the content of oxygen in the waste relative to carbon atoms in building molecules of the waste is reduced. This concurrently causes removal of halogens in said building molecule and transferring the halogens into the slurry. The slurry then is cooled and dewatered and fed into a combustion section of the boiler. The waste slurry to be subjected to the hydrothermal reaction can be sorted into two portions for separate storage. One portion is a waste slurry the pH of which will increase as a result of the hydrothermal reaction. The other portion is a waste slurry the pH of which will decrease during the hydrothermal reaction.

Abstract: A bypass is provided between the hot air pipes carrying heated air from a furnace and a cold air pipe carrying the return air to the furnace. A certain percentage of the air thus is bypassed. A scented pellet is provided in the bypass and is heated when the air is heated, and thereby evaporates a scent into the air. (It will evaporate scent when the air is cold, also.) Passage of the scent to the cold air pipe insures that it is heated again by the combustion chamber of the furnace, and the scent thereby is fairly evaporated and spread through the heating system.

Abstract: In a purifier for removing particulates from an exhaust gas, a pressure difference, and a flow rate of the air supplied to the filter element is adjusted in such a manner that a difference between a pressure difference of an air across a substantially invariable air flow resistance before the air reaches a filter element collecting and storing the particulates therein and a reference pressure difference is a predetermined value, while heating the air.
