A portable apparatus for incinerating matter in situ includes a container defining an open base and an interior incineration chamber. The open base has a perimeter lying in a single plane. A plurality of ignitable incendiary devices are mounted in the interior incineration chamber above the open base and around a perimeter of the interior incineration chamber. The ignitable incendiary devices are oriented such that flames produced by the incendiary devices are directed inwardly towards a central axis of the incineration chamber. The incendiary devices surround and point toward the matter to be incinerated.

A cement kiln burner device includes a powdered-solid-fuel flow channel, a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, having means for swirling an air flow, an outer air flow-channel group placed concentrically in an outermost side outside the powdered-solid-fuel flow channel, having three or more second air flow channels adapted to form means for straightly forwarding an air flow, and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channels are placed proximally to each other in a radial direction within a range where air flows ejected from the respective second air flow channels are merged to form a single air flow, and are configured to control flow rates of the air flow ejected from the respective second air flow channels, independently for each second air flow channel.

A cremation accelerant module includes a carrier and flame accelerant material. The carrier comprises a combustible tube, such as, for example, one constructed primarily of paper. The flame accelerant material is disposed in solid form within the combustible tube. The flame accelerant material has a melting temperature, and a combustion temperature that is higher than the melting temperature. The combustible tube has a wall thickness selected to maintain sufficient structural integrity at the melting temperature to retard the flow of the flame accelerant materials in a molten state. The combustible tube has a wall thickness configured to degrade or burn sufficiently at the combustion temperature to allow the flame accelerant material to combust.

A perfected cremation process includes the following operations: placing a mortuary coffin inside a crematorium oven configured to carry out the combustion of the mortuary coffin and cremation of the corpse contained in its inside; initiating the combustion of the mortuary coffin; conducting the combustion of the mortuary coffin for a time such as to achieve the degradation of the mortuary coffin, wherein it is provided arranging a combustion accelerant on the outer surface of the mortuary coffin, preferably on the outer surface of the cover of the mortuary coffin, before the initiation operation. This accelerant includes a compound selected from alkali metal salts, alkaline earth metal salts, ammonium salts, alkali metal peroxides or alkaline earth metal peroxides.

A method for remediating a contaminated porous matrix including selecting the type and quantity of organic fuel to create a smolderable mixture of the organic fuel and contaminated porous matrix, and controlling the rate of oxidant addition to manipulate the relative proportions of oxidative breakdown products, non-oxidative breakdown products, and non-destructive remediation processes. The method further involves collecting the volatilized contaminant, and any gaseous breakdown products of the contaminant.

A trash burning receptacle is fashioned as a cast iron material of construction with a venting lid, an access door, and a removable tray. The receptacle is configured to be submerged in the earth with a restricting enclosure surrounding it.

Low carbon atomic number mixed alcohol gel paste or pancake and straw charcoal grate combination of ignition agent, with fossil fuels such as bituminous coal lignite, straw branches and other agricultural and forestry waste, polyolefin and other synthetic organic polymer waste, other combustible solid and semi-solid low-value raw fuels, with non-toxic auxiliary materials carefully crafted high volatile column ignition coal and lower coal, are stacked in the insulation—fire-resistant furnace core. Throw in a small strip of burning paper to ignite the igniter from the top, that is, start long flame combustion, followed by the ignition coal on fire, its surface red hot coal layer will be designed to move down more quickly and gradually, to the lower coal on fire.

A mixed low-carbon alcohol ignition agent in a gel paste or a thin cake, and a cylindrical fire-leading coal and a cylindrical coal placed underneath having a high volatile content and honeycomb-like vent holes which are made from solid fuels such as bitumite, lignite, biomass fuels, polyolefin and waste plastics as well as nontoxic excipients, are vertically combined into a coal pile to be combusted in a furnace core, and the number of the pile may be increased. A firing slip of paper is thrown in to ignite the ignition agent from the top, a long-flame combustion is generated soon, and the fire-leading coal catches fire. A high-temperature zone ranging from 400 C. to 800 C. may be rapidly formed in a simple large combustion chamber between the top of the coal pile and the fire-gathering plate. The radiant heat plus the conductive heat is greater than the convective heat, and the red hot coal layer on the surface of the fire-leading coal will gradually move down at a rapid speed, which causes the coal placed underneath to catch fire. The three major components of the coal pile are elaborately formulated and prepared. The material of the furnace core must fit the coal pile. The high-temperature zone is in the upper portion and the low-temperature zone is in the lower portion, which produces an orderly, long-flame, complete combustion and a static combustion without an air blast, thus realizing a combustion with zero smog throughout the whole process starting from the moment of ignition. In addition, the sulfur-fixing rate is high, the cleanliness of the exhaust gas is close to that of natural gas, the exhaust gas may be discharged directly, the heat-generating efficiency is high, the cost is low, the slag is used as a fertilizer, and it is suitable for various small- and micro-sized stoves for heating and warming.
