Answer (1 of 2): Bed material support coal in firing zone. Bed material does not decompose at firing zone temperature so stays. With higher specific gravity does not fly up with burnt coal or gases. Gaps in bed material allow primary air to distribute well in furnace. It allow ash buildup above b
Answer: These boilers work on fluidization principle To ensure particle donor stick to each other you have control the operating temperature of bed below ash melting and optimum for sulphur capture and so on This operating temperature is achieved by the bed material or mineral matter popularly
Dec 14, 2016 · CFB boiler bed material in fluidized bed boilers is the same with the former and the latter the main difference is that the former high fluidization velocity, the materials in the flue gas concentration is high, a large number of materials materials were separated furnace exit back to back to the furnace after the separation, that a large
Bed Material . 1. To start with the bed material is sand. Some portion is lost in the ash during the operation and this has to be made-up. In coal fired boilers the ash from the coal itself will be the makeup material. 2. When firing bio fuels with very low ash content sand will be the makeup bed material.
Mar 08, 2019 · Coal CFB Boiler uses bed material (such as silica sand) to support the combustion of coal around 900°C to generate heat. Steam produced inside the combustor can be used for power generation in steam turbine. Coal CFB Boiler can suit varying particle size (1-10mm) and varying fuel quality (from anthracite to lignite, petroleum coke).
