Used 75T sell three fluidized bed boiler, fluidized bed boiler used Overview

Used 75T sell three fluidized bed boiler, boiler plant in Jinan 2007 machine, the basic unused after installation. 53 kg pressure circulating fluidized bed boiler desulfurization desulfurization process is a combustion furnace, limestone desulfurization absorbent, coal and limestone from the lower chamber into the boiler, the primary air from the lower air distribution plate into the secondary Central air into the combustion chamber. Thermal decomposition of limestone, calcium oxide and carbon dioxide. Blast from coal, lime particles form a fluidized bed combustion chamber intense disturbance, SO2 in the flue gas of coal-fired calcium oxide in contact with a chemical reaction to be removed. In order to improve the utilization of the absorbent, the unreacted calcium oxide, fly ash and desulfurization products involved in recycling back to the combustion chamber. Ca S ratio reached about 2 to 2.5, the desulfurization rate of 90%. Fluidized bed combustion characteristics are: 1. Clean burning, desulfurization rate of up to 80% ~ 95%, NOx emissions can be reduced by 50%; 2. Fuel adaptability, especially for the low-sulfur coal; 3 high combustion efficiency, up to 95% to 99%; 4. Good load adaptability. Load adjustment range of 30% to 100%. Fluidized bed airflow to crush AMD technology fluidized bed airflow to crush AMD is to be pulverized material is placed in the device container vessel from the bottom of the device through the air, pulverized. The circulating fluidized bed, into the container below the speed of the air sucked equipment improved, so that the material particles inside the container was boiling suspension was blown to pieces. While the upper container exports, high-speed classification means superfine collection. Circulating fluidized bed airflow to crush AMD technology developed in recent years is an environmental grinding technology. It has a smash wide adaptability, high crushing efficiency, less coarse particles entrained, low cost, load regulation than large and fast load regulation and other advantages. Circulating fluidized bed low cost stringent ultrafine grinding parameters, meanwhile, for a variety of non-metallic materials, it has comprehensive advantages in terms of load adaptability and ultrafine comprehensive utilization, energy-saving environmental transformation superfine jet mill provided an effective way.
