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.
