The reason for the inner coil to fail is the heat flux and its outlet arrangement. The outer tube gets little more heat. The inner coil length is 1516 mm and the outer coil length is 2162 mm. The steam generation in the outer coil is more. This can obstruct the flow rate in the inner coil due to arrangement of stubs in the bed coil outlet header.

The fluidized bed combustion (FBC) takes place at about 840°C to 950°C for coal. Since this temperature is much below the ash fusion temperature, melting of ash and associated problems are avoided. Main reasons for consideration of Fluidized bed combustion Boiler :-Liberty of fuel choice – Normally fuel burns at 700 to 900 Deg C.

poor combustion and bed coil failures. The subject of fluidization is reviewed here for the benefit of operating engineers. The behaviour of a fluidized bed is difficult to predict since the parameters such as the particle size, shape and density are not simply some numbers. These parameters in real world fall in to wider range.

To cope with this problem, we proposed the concept of Force-Balanced Coil (FBC), which is a helically wound toroidal coil. The FBC can minimize working stresses by selecting an optimal number of poloidal turns. However, the winding of the FBC has a complex three-dimensional shape that can make the manufacturing of the helical …

Ignition Coil Failure. All six coils on the 01 Odyssey are protected by a single fuse. If ANY ONE of the coils fails, the fuse will blow and the engine wild stop. To avoid being stranded (again), I installed a six fuse block, one fuse for each coil. The OEM Honda fuse is 15amp, so I used 5 amp fuses for the individual coils.
