WebMay 1, 2007 · The boiler, in a Mid-Atlantic state, has a peak rating of 114 MW and fires either Eastern bituminous coal alone or a mixture of coal and up to 10% (on a heat input basis) clean wood waste. WebConsumers wanted the boilers to be as small as possible to minimise the amount of floor space needed by the boiler house, and hence increase the space available for other purposes. Boilers with smaller dimensions (for the same steam output) tend to be lower in capital cost. Table 3.2.4 demonstrates this, and other factors.
