A process for carbonization and pyrolyzation of hydrocarbons containing, non-fluid materials is characterized by a continuous plug stream in shafts within a refractory structure. Within the shafts, the materials are heated by the hot inner surface of the shafts without air admitted to enter the shafts. Furthermore, the developing pyrolyze gas is led directly to combustion channels around the carbonization shafts within the refractory structure where a controlled amount of air or oxygen is added, partially combusting the gas, providing the heat for the process. Aim of the process is to convert different waste streams into reusable elements without CO2 emissions, to take away hazardous materials, to produce syngas, to extract hydrogen and to create a carbon rich residue fit for mining of, among others, metals, CaO and phosphor.

A ground supported power boiler is described combining a refractory lined and insulated conical floor; an insulated cylindrical combustion chamber; a cylindrical furnace with water tube wall; a rectangular convective section; a single vertical steam drum; tangential injection of the fuel and combustion air; means for fluidizing the fuel bed; means for selectively stripping particulates from the flue gases; multi-stage particulate stripping and filtering from flue gases, means for using the walls of steam drum as steam/water droplet separator, means for recirculating and capturing heat from the flue gases; means for pressurizing the interior of the boiler above atmospheric pressure; means for heating and drying fuel prior to feeding the fuel to the boiler; means for creating hydrogen shift reaction; means for eliminating any need for sootblowing; and designed to not require the use of an induced draft fan.

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.

A boiler apparatus for waste incineration includes a combustion chamber having a waste inlet formed on one side and combustion spaces for incinerating the introduced waste. Air injection pipes are vertically spaced apart from one another from a lower part of the combustion chamber, extend along the circumference thereof, and have injection holes to inject air toward the center of the combustion spaces. An air supply unit supplies air to each of the air injecting pipes separately, in response to a control signal. Temperature sensors are mounted in the combustion spaces in respective stages vertically divided on the basis of the air injecting pipes, to measure a combustion temperature of the combustion space within the combustion chamber. A control module controls operation of the air supply unit, to control an injection amount of air fed to the combustion space according to a combustion temperature measured by each temperature sensor.

A hand-held, disposable incinerator for medications and electronic storage media includes a body and a lid, a layer of insulation, and a chemical burn agent, which on ignition produces both heat and oxygen to destroy the contents. Exhaust gases pass through a non-combustible filter to remove most solid particles and contaminants, followed by a second, higher-efficiency filter. Hot gases exiting from the incinerator then desirably ignite again from their own heat, consuming remaining volatile organic matter distilled from the items being destroyed. An igniter, which may be a fuse, a pull-tab-activated pyrotechnic delay or an electronically remote-triggered igniter, provides a delay for the safety of the person using the incinerator. Heat generated within the burn chamber decomposes most organic materials, melts soft metals including aluminum and electronic solder, and renders data storage devices unreadable. At least an inner portion of the device may be safely discarded.
