The Role of Coal Characteristics in Boiler Operation

In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro- blems in boiler operation or performance. See Figure 1 for typical
