Abstract

Abstract Burning of solid waste material such as: slash and small growth, resulting from logging operations to acquire merchantable timber and wood products and/or to clear right of ways for vehicles or power lines; selected debris from demolition operations; selected debris taken from transfer stations and/or deposit areas where city wastes are received; and selected debris from wastes created at dwellings; is accomplished in a manner whereby controlling the burning process in an incinerator eliminates completely or in varying degrees the amount of pollutants discharged into the atmosphere. At the same time this method reduces the direct operating costs, possibilities of setting ancillary fires and the need for extended tending and/or dousing of several fires. In some embodiments, this incinerator is completely transportable to the general area over public roads and then after arrival to specific multiple locations off public roads it is conveniently moved over unimproved land to places where the incinerator is needed.
