Erosion of boiler tubes is a significant contributor to the maintenance costs of sugar mills. In some severe cases, boiler convection banks have required a complete retube, a major capital cost. The problem can be particularly severe in boilers with baffled convection banks. Tube wear rates are the highest where there are high local gas velocities and high local particle concentrations. Wear ...

If a boiler is long, that is, more than 20 feet, long stays would sag in the middle and not take up the full stress on the end plates. For long boilers, gusset and diagonal stays are used. This form of boiler stay, shown in Fig. 30, is made of wroughtiron plate riveted to angle irons ; the angle irons being riveted to the end and shell. Boilers ...

the biomass for Washington boilers comes from mill residues. Mill residues are waste wood from manufacturing operations that include sawmills, pulp and paper companies, and other millwork companies involved in producing lumber, pulp, veneers, and other composite wood fiber materials. Primary mill residues are usually in the form of bark, chips, sander dust, edgings, sawdust, or slabs. .
A high pressure watertube boiler (also spelled watertube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steamgenerating smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the waterfilled tubes ...
· Observing a boiler tube leak with thermography. UT is also used largely to determine internal oxide thickness among steamcooled tubing. Over time, superheater and reheater tubing sustain elevated temperatures and experience internal oxide (magnetite) growth. This oxide layer interferes with the steam flow cooling effect, reduces boiler efficiency and leads to chronic overheating of the tube ...

mills focus almost exclusively on tube thickness measurements, often making far more measurements than are needed to calculate the remaining life of tubes in particular parts of the boiler. To determine what maintenance is required in a recovery boiler, an experienced corrosion inspector should tailor a nondestructive test program to monitor corrosion problems found during previous ...
