摘要： PURPOSE:To improve efficiency, function and profitability by setting a stabilizing burner whose flame is blown downward on the upper position of a tank of a small-sized boiler by fluidized bed burning method. CONSTITUTION:A boiler tank 9 is formed as an once-through boiler by connecting an upper doughnut-like steam drum 9a and a lower water drum 9b with a plurality of evaporating tubes 9c, a primary air flow passage 13 for supplying to a fluidized bed burning chamber 2 and a stabilizing burner 5 is set between an outer casing 12, a boiler tank 9 and a furnace wall 10 and heat radiation from the furnace wall 10 and the tank 9 is utilized to preheat and supply primary air. Therefore, since heat radiation from the fluidized bed burning chamber and the boiler tank is recovered to preheat and supply the primary air for a stabilizing burner 5 and fluidized bed burning, combustion efficiency can be improved considerably.

摘要： PURPOSE:To provide a positive ignition of a solid fuel and always keep an appropriate inter-layer temperature by a method wherein each of a combustion air supplying and controlling device, a heating burner automatic ignition device and a solid fuel automatic supplying device are controlled and operated under a sequence based upon the ignition temperature of the solid fuel and the temperature of self-sustained combustion. CONSTITUTION:A sequenser 18 for executing a sequence control in response to a sensing signal of a temperature sensor 16 within a fluidized bed has a micro-computer. As an applied fuel, oil cokes is used. A temperature condition is set to have three stages of lower than 750 deg.C, 800-950 deg.C, and higher than 950 deg.C. When a temperature within a fluidized bed corresponds to each of these three stages, each of a combustion air supplying and controlling device 5, a thermal medium particle heating burner automatic ignition device 7 and a solid fuel automatic supplying device 10 is controlled for its proper driving. It has a sequenser set to enable a stable fluidized bed combustion to be maintained.
