| Abstract: | Heat transfer coefficient for the heated surface is the key parameter for the design of a circulating fluidized bed boiler. Theoretical analysis of the heat transfer mechanisms was used with experimental results to develop a heat transfer coefficient calculational method for a heater in a circulating fluidized bed furnace. The heater size, heating conditions, and the material density were considered in this method. The calculated results agree well with the experimental values, with errors of less than 4%. This calculational method can be used in the design of circulating fluidized bed boilers with capacities from 130t/h to 420t/h. |
| Keywords: | circulating fluidized bed boiler furnace heat transfer coefficient calculation methods |
