The parameters shown in Figure 7 influence the mechanism of deposit formation and must be considered in the evaluation of processes expected of reducing furnace availability. The processes must be considered to be directly dependent on the properties of the fuel. The major influences on deposits in pulverized fuel firings... [Pg.404]

The simultaneous splitting and distribution of solids-gas mixtures for applications requiring multipoint injection, where the mixtures are transported usually under positive-pressure conditions. Some common examples include tuyere injection for blast furnaces, large burner nozzles for pulverized coal-fired boilers, small coal-fired plasma torches providing startup and support energy for boilers, injection of pulverized fuel into calciners, etc. [Pg.754]

Fluidized bed combustion of coal is used to reduce the emission of sulfur dioxide and NO into the enviromnent. In this technology the pulverized fuel is burnt in a fluidized bed combustor after being blended with limestone or dolomite, which act as soibents for SO2. The burning temperature is significantly lower than is common in the production of fly ashes in suspension-fired furnace chambers, at around 850°C. The process may take place at atmospheric pressure (atmospheric fluidized bed combustion, AFBC) or elevated pressure (pressurized fluidized bed combustion, PFBC). [Pg.138]
